ABSTRACT
The purpose of this study is to investigate the influence of advertising on consumers’
brand preference of antibacterial soaps. Due to its persuasive impact through
developing positive attitudes towards the product, advertising has been considered
as a major tool in the marketing mix by multiple authors including Kotler (2013).
Thus, understanding how and what made consumers to be motivated towards
purchasing a particular brand brings value to organisation with increased sales and
market share. Similarly, creating brand preference has become an imperative
indicator for any business in the world today. Brand preference is a process which
involves brand awareness, brand image, brand association, perceived quality and
brand loyalty. Accordingly, 150 respondents were selected using convenience
sampling method and questionnaires were distributed among them in order to
identify the research problem within the market segment of antibacterial soaps.
Descriptive analysis used by the researcher to analyse the results which revealed
that age groups as well as gender were equally influenced by advertising for their
preferred brand of soap. Further, research results indicate that advertising create
major influences on consumers’ preferring a particular brand in terms of the brand
preference factors identified as brand equity factors as highlighted above. The
necessity for high preference to advertising is therefore highlighted for companies in
order to retain and increase their market share through developing advantageous
marketing strategies for the brands.

CHAPTER 01 - INTRODUCTION
1.0 Background
Understanding the intensity of advertising is imperative for researchers as well as
practitioners (Clark et al., 2009) as it manipulates and propagates consumer
purchase intentions than other aspects of the marketing mix (Belch and Belch, 2003,
p. 18) due to its ability of reaching a vast audience at a considerably lower cost
(Etzel et al., 1997). Yet, advertising considered to be more expensive promotional
method in the marketing communication mix. Marchand (1985, p.28) identifies
advertising from public perception as an “economic waste” against the advertisers’
perception that has been viewed as a tool to acquire public recognition as well as
admiration that leads to increase sales and customer satisfaction.
In Sri Lanka companies spend heavily on advertising to generate, maintain or
increase market share (Lalanananda, 2007). According to industry data, annual
advertising expenditure in Sri Lanka has risen up to Rs. 5.5 billion in 2013 (Nielsen,
2015) compared to Rs. 2 billion in 2000 (Lalanananda, 2007). Corporate sector in Sri
Lanka views advertising as an investment an organisation make for future (The
Island, 2007). Hence, this research is focused on identifying the research problem;
the influence of advertising on consumer brand preference within the vicinity of anti-
bacterial soap market segment in Sri Lanka.
Modern day advertising is far more competitive where advertisers employ various
advertising strategies and techniques in attracting, persuading and convincing target
groups directly influencing their purchasing decisions and patterns in ways such as
10
constructing a problem diplomatically which can be solved only by using a certain
product. Similarly, anti-bacterial soaps advertisers target consumers with
comprehensive advertisement methods which contain comparative data and
problem solvencies to explore and influence consumer behaviours increasing
constant demand and competition.
According to LMRB data, Total Sri Lankan soap market value is Rs. 20 billion in the
year 2014 whereas the total volume of the soap is 39,464MT. Lifebuoy maintains a
considerably large market which is 68% among four brands including Dettol. It is
evidence that anti-bacterial soaps have an emergent demand among consumers as
a hygienic product used to prevent illnesses.
1.1 Overview/ Rational
In Sri Lanka private sector’s involvement in driving the economy is 80% (Athukorala,
2013). Hence, consumer demands with the inflationary pressure affecting them, to
be maintained smoothly. Below graph reflects the fluctuations in the soap industry
within a period of two years. Thus, Lifebuoy shows a decline in the market volume

compared to other brands that shows a slight increase. Athukorala (2013) identifies
corporate sector has demonstrated a resilient growth in business still investing on
brand building. Consequently, Rs. 34 billion has been spent on advertising by 15 key
companies in first half of the year 2013 to attract consumers and to create brand
loyalty, driving mind awareness.
However, advertising to create brand preference to be linked with consumer
lifestyles comprehending how and why brand preference is vary as it is utmost
important for advertisers to validate if sales are generated subsequently for the
money spent on advertising.
1.2 Current Situation
An increasing number of anti-bacterial soap brands are available in the market
directly facilitating the amplified competition for increased market share. Out of
several brands, Lifebuoy and Dettol devotedly struggle for market leadership.
Lifebuoy, being in the market for more than 120 years (Unilever, 2015) has

established their brand in consumers’ mind for more than ten decades employing
exceptional advertising and branding strategies. Dettol, however, was a popular
brand name in the country for more than 55 years with Dettol anti-bacterial liquid,
has re-launched their range of products accumulating antibacterial soaps in the year
2010 (Sunday Observer, 2010) further establishing their brand in Sri Lanka
becoming an intensive competitor to Lifebuoy.
1.3 Problem Statement (or, Research Question)

CHAPTER 02 - LITERATURE REVIEW
2.0 Introduction
According to Sekaran and Bougie (2010, p.38) literature review is a step by step
process involves in identifying published or unpublished work provided through
secondary data on relevant topics, problem identification and documentation. On the
other hand, Fink (2005, p.3) identifies research as a systematic, explicit and
reproducible approach for discovering, evaluating and combining existing work
produced by different bodies. Knopf (2006, p. 127) stresses the benefits of
conducting a literature review includes providing a general overview of a body,
reveal the past work, offer new ideas and assist determining problems or flaws. A
good literature review, however, provides the base to develop a comprehensive
theoretical framework for further investigations, preventing waste of resources,
simply avoid “reinventing the wheel’ (Sekaran and Bougie, 2010, p.39).
2.1 Definition of Advertising
Advertising definitions proliferate in today’s world. Accordingly, Kotler et al. (2014, p.
429) delineates advertising as “any paid form of non personal presentation and
promotion of ideas, goods and/ or services by an identified sponsor”. On the other
hand, Green (2012, p.6) defines advertising as a “paid form of communication by
individuals or companies, with an aim of influencing people to think or act in a
particular way providing information”. Further, Yeshin (2006, p.1) sees advertising as
a paid, non personnel method that used to communicate and manipulate consumer
behavior.
14
Common advertising objectives are identified as, behavioral constructs that generate
trial purchases, attitude changes and measurements, position, brand building and
creating brand awareness (Sawanth, 2012, p.56). Hitherto, the driving force of
advertising is to create brand awareness inducing potential consumers to consider
as well as to remind existing consumers of an existing brand (Ntiamoah, Egyiri, and
Kwamega, 2014) leading to create a positive effect on brand preference over
competitive brands influencing the brand choice purpose (Barker, 1999). In contrast,
Ewen (2008) is of the belief that the basic purpose of advertising is to provide
efficient and massive distribution of products whereas the functional goal is creating
consumers’ desires or habits.
Further, Ibid’s (n.d cited in Tahtinen, 2006, p. 156) indicates advertising as a paid,
mediated form of communication which premeditated in persuading enabling the
receiver to make an action. This is further illustrated by Tom and Eves’s (1999, p.39)
perception of the principle of advertisements that is to inform as well as to persuade.
Furthermore, Hussain et. al., (2008, p.29) state advertising involves in delivering
allied information of product or service to potential consumers affecting their
purchase intention. Several studies suggest advertising facilitate the effectiveness of
advertisements in terms of brand recall, persuasion or brand preference (Keller,
Macdonald and Sharp, 2000).
Nonetheless, Belch and Belch (2008) argue advertising is not the strongest
determinant of purchasing behavior as the consumer is more reactive towards
messages of preferred brands and total advertising rarely affect the total market size
(Vakratsas and Ambler, 1999). However, Martin et al. (2002) argue that several
other aspects including demographic factors induce the effectiveness of advertising.
Confirming the above, Wijesundara and Abeysekara (2010) distinguish demographic
factors, by means of age group and gender as significant attributes in consumer
behavior and brand preference due to its impact on a person’s attitude towards a
brand may vary in maturity and due to the difference of each brand’s target market.
15
However, as Aaker and Norris (1982); Rossiter and Percy (1978); Stern, Krugman
and Resnik (1981) depict advertising to be effective in increasing brand preference
is based not only on being verbal or informative but also on visual and emotional
elements. Hence, Milgrom and Roberts (1986); Nelson, (1974) argue advertising’s
role is informing consumers, either directly or indirectly (via “signalling”; about brand
attributes and/or prices where organisations employ various techniques of
advertising and brand management. As Koteler et al. (2009) identifies, there are
four types of advertisement used to increase consumer preference as give below.
Table 2.1.1 – Types of Advertisements
Types Description
Informative
advertisements
Informative advertisements are used to provide in detail
information over a product, attributes, quality and other features
where consumers’ have the opportunity to test before they
actually purchase the product. (Dukes, 2009).
Persuasive
advertisements
Persuasive advertisements are comparative marketing tools
which create consumers’ preference, liking or conviction with the
intention of gaining competitive advantages (Kotler et al, 2009,
p. 487).
Reminder
advertisements
Reminder advertisements are focused on convincing consumers
more often stimulating brand related attributes for repeat
purchasing (Dukes, 2009). However, consumers may get
irritated on the advertisements as they already aware of the
brand or the product (Kotler et al, 2009).
Reinforce
advertisements
Reinforce advertising is used to promote convenience good
which needs more detailed information as the consumers’
unawareness of the product until they consume (Dukes, 2009,
p.5). Companies whose products ranges are wide, aggressive
advertisements are used to reach brand switchers (Kotler et al,
16
2009).
Author Developed (2015)
Considering the above, as Trehan and Trehan (2009) describe, selecting the right
media that carries the advertiser’s message to target audience is important for
organizations to obtain a maximum output. Hence, Wells, Burnett and Moriarty
(1995) Identifies television as a traditional medium provides a strong consumer
based advertising, which is an appealing medium due to its extensive coverage of
the market, geographic flexibility and consumers’ positive attitude towards the
medium than other mediums such as radio, display ads, social media and or
magazines. Supporting to the above, Lavidge and Steiner (1961) describes the
process of steps in advertising that force consumers with their purchasing attitude as
given below in the table 2.1.2.
Table 2.1.2 – Steps of Advertising influence on consumers
1. Potential purchasers yet unaware of the existence of the product;
2. Simply aware of the existence of products or services,
3. Awareness of the products’ offer,
4. Having favorable attitudes over products or services;
5. Having a preference of certain brands over other aspects or brands;
6. Preference and desire to make the purchase,
7. Actual purchase attitude
Source: Lavidge and Steiner, 1961
Supporting to above communication perspective, Campbell and Keller (2003, P.
293) affirm “Negative uncertainty created by unfamiliarity should be higher for a new
ad from an unfamiliar brand sponsor as compared with a familiar brand sponsor”.
However, as Tellis (1988, p.142) stress consumers’ exposing repeatedly to a
17
favorable ad may result getting further opportunities for attention, retention and
cognitive collaboration where positive attitudes provide more ability of recalling than
the negative attitudes (Goldsmith et al., 2002).
2.2 Attitude towards Advertising
Attitude towards the ad is an effort influencing consumer preference through a
favorable attitude created towards the advertisement transferring to the advertised
brand influencing brand choice (Shimp, 1981, p. 9; Gresham and Shimp, 1985, p.
10). As MacKenzie, Lutz and Belch (1986) identify attitude toward the advertising is
a predisposition created through continuous exposure to an advertisement which
leads consumers to respond favorably or unfavorably towards a brand.
Psychologically, Ajzen and Madden (1985, p.454) identify attitude towards behavior
and subjective norm as two predictors that determine the behavioral intention.
Accordingly, they believe a person’s attitude influences the total outcome of his
responses towards an object. Nonetheless, Kraus, (1990, p.7) in his research found
attitude-behavior relationship is affected by variables refers to as attitudinal,
behavioral, personal, and situational mediated with direct experience, certainty or
accessed from memory. Thus, attitude envisages future behavior in a significant and
substantial manner. According to Moore and Hutchinson (2005) brand attitudes are
influenced by the consumer beliefs and advertising reactions. Thus, generating
positive or negative attitudes through advertising facilitates brand consideration.
On the other hand, Ajzen and Fishbien (1975) argue beliefs are the sole mediator for
developing attitudes and change of consumers. However, evidences support as to
beliefs as well as cognitions related to products affecting consumer purchase
intention and brand attitude (Batra and Ray, 1986, p.234; Mitchell and Olson, 1981;
MacKenzie, Lutz and Belch, 1986). Nonetheless, Tellis and Fornell (1988) stress
advertising sends a signal of the quality of the product, where consumers are less
responsive towards advertising compromise with low quality.
18
However, as Berlyne (1970) cited in Stang, (1975, p.1) and Cacioppo and Petty
(1979) depict message effectiveness increases at lower levels and decrease with
the increase of repetition. Even so, consumer attitudes toward the ad can be
interactively determined by the negative publicity, advertising, and existing brand
attitude (Stammerjohan et al., 2005).
Hence, MacKenzie and Lutz (1989); Brown and Stayman (1992) and Batra and Ray
(1986) identify attitude toward the ad as a significant mediator in developing brand
attitudes shaping consumer behavior.
2.3 Advertising and Consumer behavior
Adelaar et al. (2003, p.253) classify consumer buying behavior as the product
purchase intention. The consumer is ‘rational’; where a variety of factors
manipulates consumers’ purchasing behavior (Watson et al., 2002). Reaching and
influencing potential consumers’ awareness, attitudes and buying behavior are the
critical endeavor of advertising (Abideen and Saleem, 2011, p.56). Conversely,
Schiffman and Kanuk (2009, p. 23) outline consumer behavior as consumers’
activities related to actions such as search, purchase, usage, evaluation and
disposing of products and or services satisfying their needs.
Further, effective advertisement manipulates the attitude towards a brand leading to
purchase intention (Abideen and Saleem, 2011, p.56) influencing consumers to
switch to the advertised brands (Raj, 1982, P.77), stimulating and reinforcing brand
image and loyalty. Tellis (P. 142) argues advertising is not the strongest
determinants of purchasing behavior, but the brand loyalty. In contrast, Nelson
(1974, p. 732) stress advertising creates less impact towards creating brand loyalty
due to its effect on current purchase than future purchases. Accordingly, consumer
behavior can be scrutinized by means of brand awareness, association and loyalty
(Malik et al., 2013, p.118; Shehzad et al., 2014) which all together considers as
brand equity (Kotler, 2013).
19
2.4 Brand and Brand Equity
The brand, is defined as a combination of mark, logo, name, symbol, word, sentence
that companies use to differentiate their product from others in the market
(Investopedia, 2014). Brand as a whole is a trademark proclaiming a promise
comprised of distinctive characteristics linked to a brand (Phillips, 1998, p.43).
Building and reinforcing the brand image is a key to profitability and growth (Belch
and Belch, 2003, p.15).
On the other hand, brand equity is defined as the differential effect of brand
knowledge on consumer response to the marketing of the brand (Keller, 1993, p.1).
Brand equity arises the time consumer recognizes or seizes an exceptional brand in
memory, where repeat exposure facilitates the consumer ability to recall and
recognize any brand.
According to Donthu, (2000, p.195) Higher advertising cost is often related to higher
brand equity. Conversely, Tuominen (1999) stresses brand equity is utmost
important for advertisers to create differentiation that direct to competitive
advantages in situations where value is a nonentity. Accordingly, intangibles such as
trademarks/ patents, the technology used or technical/ manufacturing know how add
value to brand equity through marketing investment. Brand equity, in forms of
increase advertising effectiveness, constructing brand loyalty, improved profit and
uniqueness generate value to organizations.
Moreover, Brand equity is a multidimensional conception of brand awareness, brand
association, brand image, perceived quality and brand loyalty (Keller, 1993; Donthu,
2000; Aaker, 1996; Tuominen, Chi et. al. (2009) which are further discussed below.
20
2.4.1 Brand Awareness
Brand awareness refers to the salience of a brand in consumers’ mind (Aaker, 1995,
p.141). Huang and Sarigöllü (2012, p.92) see brand awareness as ‘decision
heuristic’ due to its nature of impacting consumer decision making. On the other
hand, brand awareness is identified as the first element distinguishing brand
knowledge which consists of consumer brand recognition and brand recall
performance (Keller, 1993, p.3; Tuominen, 1999). Brand recall is the ability of
consumers’ prior exposure to a particular brand where brand recognition refers to
the unaided reclamation of a brand from consumers’ memory.
Accordingly, Hoeffler and Keller (2002, p.79) brand awareness is the consumers’
ability of recalling and/or recognizing a particular brand distinguished through terms
depth and width. Depth refers to the level of consumers recall or recognition where
as width refers to the arising of any brand in the consumers mind when purchasing
or consumption state. Hence, higher depth or width in brand awareness aid
increased sales. In low involvement conditions, frequent exposure to brand
advertisement, increase the level of brand awareness (Yoo, Donthu and Lee, 2000,
p.206) Hence, raising brand awareness consequently facilitates a brand to be
included in the consideration set of purchase (Macdonald and Sharp, 2000, p.12;
Hoyer and Brown, 1990; Baker et. al., 1986; Nedungadi and Hutchinson, 1985).
In his research that replicated Hoyer and Brown’s (1990) brand awareness of choice
theory, Macdonald and Sharp (2000, p.12) indicates brand awareness creates a
strong effect on consumers’ preference for a repeat purchase than the price effect
influencing perceived quality where consumers will choose a known brand even at a
high price. Hence, Hoyer and Brown (1990, p.141) identify brand awareness as the
basic level of brand knowledge that involves at a slightest recognition of the brand
name.
21
Conversely, Brondoni (2001) sees brand awareness as a crucial point of difference
between a brand and its competitors. Accordingly, Anh (2013, p.9) stress, having a
high level of awareness and familiarity of a brand contributes to brand equity.
2.4.2 Brand Image
Consumers’ concepts, feelings or attitudes over a brand refer to as the brand image
(Tuominen, 1999). Brand image is identified as a subjective and perceptual
occurrence produced through consumer interpretation, reasoned or emotional.
Strong brand images improve a person’s personality (Keegan, Moriarty and
Duncan). In contrast, Padgett and Allen (1997, p.50) affirm that brand image acts to
delineate the product for consumers’ differentiating organization’s offer from
competitive offers. Further, they describe that concept of brand image is consumers’
association and understanding of attributes, functional consequences as well as
symbolic meanings of a brand which directly connected to advertising. As Kotler and
Amstrong (1996) and Shimp (1997) define the purpose of advertising is to inform,
persuade and remind consumers, increasing brand related stimulation (Padgett and
Allen, 1997, p.50).
2.4.3 Brand Association
Brand association refers to the knowledge pertaining to any brand in consumers’
mind which represents the entire brand equity Huang and Sarigöllü (2012, p.93). On
the other hand, Tuominen (1999, p.76) elucidates brand associations as
‘informational nodes’ connected to the brand in memory containing the denotation
for consumers that included related or unrelated attributes to the product as well as
figurative or the attitudes. Accordingly, the presentation of information related to a
brand consistently facilitates strong brand association that occurs with consumers
identification of the need arises through attributes and benefits they possess (Keller,
1993).
22
2.4.4 Perceived Quality
Fornell et al. (1996) believe that brand quality perception has an effect on
customer’s satisfaction that affected future buying behaviors. Due to perception is an
emotional connection, consumer’s purchase decision could be decided based on the
perception of a brand quality, not the actual quality. Therefore, a bad publicity could
negatively affect the brand even the actual quality is good (ALG, 2012). Dhadhal
(2011) claimed that through brand equity, perceived quality is one of the few factors
that provide value enhancing consumer satisfaction. He believed usage
experiences, perceived quality and brand relations can affect customer’s
satisfaction. Grönroos (1984) categorized customers’ perceived quality of service in
three dimensions, refers to as functional (process of delivery to customers),
technical (outcomes of the service, to the customers), and image (customers’ view of
the company).
Applying to the scope of this study, knowing the anti-bacterial soaps are from a good
quality brand can affect the experience of using it. Therefore, better perception of
quality leads to higher success possibility of brand (Allenby and Rossi, 1991; Chang
and Wildt, 1994; Dawar and Parker, 1994).The higher the overall perception on
quality will translate into higher perception on the brand. Perception of quality of
product and its brand is influenced by other factors such as product variety (Berger
et al., 2007), product attributes (Holbrook, 1992) and packaging (Banks, 1950,
Brown, 1958, McDaniel and Baker, 1977, Miaoulis and d'Amato, 1978).
2.4.5 Brand Loyalty
Brand loyalty refers to the behavior of consumers’ repeatedly purchasing a particular
brand. Oliver (2010, p.433) identifies four phases of brand loyalty refers to as,
cognitive loyalty (loyalty based on brand attributes/ performance), affective loyalty
(attitude towards the brand based on satisfaction), conative loyalty (behavioral
23
intention or repeat purchase) and action loyalty (consumer readiness to act
facilitating to repurchase). Hence, brand loyalty is defined as an intense detained
commitment in repurchasing a preferred brand constantly despite of situational
influences or advertising effects that create brand switching behavior (Oliver (2010,
p.434).
According to Keller (1993, p.8) loyalty occurs with repeat purchasing behavior
influenced through beliefs and/ or attitudes. Better promotional strategies involve in
creating a positive brand purchase intention of consumers. Hence, Raj (1982, p.77)
distinguishes; persuading consumers who are not loyal to switch to the advertised
brand whilst retaining the loyal consumers’ drifting to competing brands as a
defensive role of advertising. In contrast, Shum (2004, p.241) recognize advertising
as an attractive/ effective method that stimulate demand yet neutralizes the
propensity of brand loyalty toward repeat purchasing and facilitate reducing the
switching cost.
2.5 Brand Preference
Brand preference is the consumers’ tendency toward certain brands that vary at a
particular time depending on one’s salient beliefs (Ajzen and Fishbein, l976, P.889)
which is identified as a measure of brand loyalty where selecting a certain brand
over competing brands, yet consumers’ accepting substitutes at a discrepancy
(Christian and Sunday, 2013, P.79). Confirming the above, Wijesundera and
Abeysekera (2010) recognize brand preference as the measure of brand loyalty
where consumers’ select a particular brand among competitive brands.
Due to its persuasive impact towards consumer brand preference, Tellis (1988 p.
142), in his research found advertising can be effective in increasing the volume
purchased by loyal buyers than wining new buyers. Thus, consumers recognize the
value of any brand with regard to the characteristics and service quality (Rio et al.,
2013, P.412). However, brand preference or attitude is considered as a symbol of
24
status due to consumers’ preference in purchasing branded items than non branded
items (Malik et al., 2013, p.118).
According to Belch and Belch (2008) well known brands create a major competitive
advantage. Asch and Wolfe (2001) claimed that human’s situational perception does
affect their action in deciding a purchase. This is due to different people can have
different kind of brand perception of the same anti-bacterial soap. For instance, the
promotional messages get into the unconscious level of recognition.

CHAPTER 03 – METHODOLOGY
3.0 Introduction
This chapter starts providing definitions for research; research methodology and
marketing research consequently. Further, the researcher intends to furnish an
overall view of the methods, techniques, tools and time frames to be used in carrying
out the research.
3.1 Overview of the Research
Walliman (2011, p.16) identifies research as a term used to identify various
investigations that anticipate uncovering remarkable or new specifics whereas the
research methods are the variety of procedures, schemes or algorithms that have
been used in the research contributing to collect, analyze and find solutions.
Whereas, marketing research is identified as a systematic and objective approach to
achieve and develop information towards formulating imperative decision making in
marketing (Kinnear and Taylor, 1996). However, this can be recapitulated as
discovering a solution to a problem or better performances responding to consumer
behaviors.
Saunders, Lewis and Thornhill (2003) relate research approach to an ‘onion’, where
the external stratum is named as research philosophy. Research approach lies
beyond the research philosophy leading to the third stratum called research strategy,
moving towards the data collection stage determining ‘time horizons’ for the
research. Hence, the researcher has applied this terminology in her research
identifying the key areas in this research as presented below.

3.2 Research philosophy and Objectives
Saunders and Tosey (2012, p.58), understanding the research philosophy is
important for researchers in developing an appropriate as well as a coherent
research design that can be justified and explained. Accordingly, Saunders and
Tosey (2012) identify three research philosophies described in Table 3.2.1 below.

Considering the above, the researcher will adopt positivism philosophy which
involves quantitative data obtained from a large sample to measure the below
objectives;
a. To determine the influence of age and gender on advertising;
b. to measure variables such as consumer brand preference, media preference
and awareness sources;
c. to measure the mediating effects of attitude towards advertising;
28
d. to determine the relationship between advertising and brand equity.
3.3 Research Approach
Research methods vary in terms of measurability criteria, features and
characteristics (Murthy and Bhojanna, 2008) that can be quantitative, qualitative or
mixed method (Creswell, 2008). The researcher decides to adopt a deductive
method to observe the relationship between variables such as advertising influence
on consumer brand preference and test the proposition using quantitative data. As
Saunders, Lewis and Thornhill (2009, p.489) describe the deductive method involves
in deducing a hypothesis from theory and or proposing relationship between
variables testing and modifying the theory using numerical data which is analyzed
using statistical procedures (Malhotra and Peterson, 2000).

3.4 Research strategy
Sekaran and Bougie (2010) discuss four research approaches; exploratory study,
descriptive study, hypothesis testing and case study. Descriptive analysis is widely
used in marketing research analysing hypothesis (Murthy and Bhojanna, 2008, p.
50). Hence, descriptive analysis to be adopted to analyze the variables using the
background information as well as the respondents’ profiles pertaining to their
preference of brands and media.
Table 3.4.1 - Benefits and limitations of Descriptive study
Benefits Limitations
Descriptive study has scientific value in
addressing appropriate research
questions (Oxford University, No date).
A “snapshot” is provided at certain
times and some variables are difficult
to measure (Frazee, 2005, p.1; Gable,
1994, p. 2).
Surveys facilitates documenting norm,
recognize extreme outcomes and
outline relationships among variables
accurately (Gable, 1994).
Accurate questionnaires are needed
and adequate time and money to be
spent on surveys (Malhotra, 2008).
Generalized for large populations,
facilitating direct comparisons within
groups (Frazee, 2005, p.2).
The researcher is responsible for
illustrating accurate results (Thomas,
2003).

3.5 Research methodology
Research methods vary in terms of measurability criteria, features and
characteristics (Murthy and Bhojanna, 2008) hence, classified as quantitative,
qualitative or mixed method (Creswell, 2008). Quantitative data is measurable where
data will be numerical in nature (Murthy and Bhojanna, 2008) and numbered data to
be analyzed using statistical procedures (Malhotra and Peterson, 2000). Hence, the
researcher will be adopting a quantitative research method to measure the variables
of media preference and brand awareness.
Table 3.5.1 - Benefits and Limitations of Quantitative Research Method
Benefits Limitations
Numbered data can be measured more
or less accurately (Walliman, 2011,
p.87)
Probability of undertaking quantitative
method is limited in certain researches
such as social welfare and social
benefits (Stern, p.35)
Opinions, attitude or behaviors can be
quantified to understand certain issues
(Sukamolson, 2005)
Gathering, measuring and analyzing
data will lead to statistical errors to be
occurred (Thomas, 2003).
Objectives are easily achieved and
recommended (Holden and Lynch,
2004).
Exploring problems in depth is not
possible (Sukamolson, 2005)
Large population can be easily
measured (Sukamolson, 2005)

3.6 Time Horizon
Cross Sectional analysis to be used due to this research is being a descriptive study
by means of a survey (Walliman, 2011) to measure the influence of advertising on
consumer brand preference.

3.7 Data Collection Method
Primary data will be collected using questionnaires as Cohen, Manion and Morrison,
(2007, p.318) describe, they are generally being used in descriptive or explanatory
researches to collect large samples of data developed to maximize response rate,
reliability as well as validity concerning on the research question and objectives
(Saunders, Lewis and Thornhill (2007, p.355).
Accordingly, structured questionnaires consist of closed ended rating questions
indicating consumer opinions (Corbetta, 2003, p.126) and dichotomous questions
with fixed-alternative options (Business Dictionary, 2015) to measure the variables.
Due to its ability of getting direct responses and feedback efficiently and effectively,
self administered questionnaires will be used with indicating the purpose of the study
Benefits Limitations
Inexpensive and less time consuming Difficulties in making a causal inference
Many outcomes and risk factors can be assessed
Only a snapshot is provided at a certain time

to respondents as it will provide a higher reliability of the information (Saunders,
Lewis and Thornhill, 2007).

As Saunders et al. (2011) state secondary data contains either published summaries
or raw data with comprehensive background information on concerned topics.
33
Accordingly, the researcher has extracted secondary data from sources such as
journal articles, web sites, reports and other publications.
3.8 Populations/ Sampling Technique
Failure or success of a research depends not only on the suitability of the methodology but
also the appropriateness of the sampling strategies adopted (Walliman, 2008). Sampling is
a scientific process of obtaining representative data from a group (Som, 1996, p.1)
and a critical point in the study of research (Saunders, Lewis and Thornhill 2009,
p.168).
Sharp, peters and Howard, (2002, p. 143) stress “any statistical method that requires
a certain size of the sample to be collected to satisfy requisite levels of confidence”.
In confirming the above, Borg and Gall (1979, p.195) suggest having larger sample sizes as
a general rule where many variables are available and relationships are expected or
predicted. Hence, 150 respondents are selected in the vicinity of Colombo out of
“2,323,826 population” (Census and Statistics, 2012, n.p) to gather data from, where
processing entire statistics is not possible (Wolman, 1954).
Furthermore, in this research, non-probability sampling technique will be used, as
Saunders, Lewis and Thornhill (2011, p.235) affirms there is no probability over the
samples being selected within the population. Hence, a convenience sampling
method is to be adopted due to its being an easy method where respondents are
selected wherever convenient for the researcher (Jackson, 2014, p.98) concerning
the demographic area selected.
Table 3.8.1 - Benefits and Limitations of Convenience sampling
Benefits Limitations
Easy and simple Highly vulnerable to selection bias
34
Useful for hypothesis generation Unclear generalizability
Less Time consuming and Cost effective Highest possibilities of sampling errors
Source: Research Methodology (2015)
3.9 Pilot Survey
The pilot test is a feasibility study to ascertain the limitation of questionnaires before
planning a large scale investigation (Thabane et. al, 2010, p. 1). According to Kvale
(2007) cited in Turner III (2010, P.757) Pilot Test allows the researcher to identify
errors, limitations or any other faults lies within the research design which require
alteration prior to the implementation of the research.
Similarly, the researcher completed pilot testing using 05 respondents who had
consent over with the prepared questionnaires. However, none of the respondents
were able to pinpoint any error or misinterpretation of the questions asked in the
questionnaire. Hence, as there was no amendment needed, the researcher
continued the investigation with the same questionnaire distributed to 150
respondents.
3.10 Data Analysis
Walliman (2011) describes the importance of statistical analysis in descriptive study,
which requires checking the accuracy of the data gathered from the sample and to
understand the findings easily. In supporting to this Miles and Huberman (1994)
state that quantitative data analysis facilitates explaining and representing research
findings in a significant manner and to illustrate the distribution and relationship
among variables. Accordingly, data will be analyzed using IBM SPSS 20 software
and MS excel and to be presented through graphs and pie charts in chapter 04.
35
3.11 Limitations of Research methodology
As Saunders, Lewis and Thornhill (2007) identify time; expenses and accessibility
prevent researcher gaining information from the entire population. Hence, Colombo
being selected as the research population, entirely accurate probability sampling is
not possible due to the inabilities of reaching every subdivision in the district.
Furthermore, gaining new knowledge is restricted due to researcher considering only
close ended questionnaires whereas open ended telephone questionnaires and or
observation methods might expand the knowledge and give new insights to the
research (Walliman, 2011, p.101; Moll et al., 1992).
Researcher has to adopt convenience sampling method with self administered
questionnaires due to poor time management and to avoid unnecessary delays and
misunderstandings occurs in simple random sampling and personally administered
questionnaires.
Finally, as Graaf and Levy (2011) argue conducting a fully ethical research is
impracticable and the success rate of any research or survey is difficult to ascertain
due to non availability of specific tool to measure.
3.12 Ethical approach to research
The researcher will be adhered to strictly ethical guidelines when sampling and data
collecting. Voluntary participants who have direct consent (Drew, 2007, p.69) over,
to be informed the purpose of the study and the procedures of data collecting
ensuring to protect privacy and confidentiality (Given, 2013, P. 10) respecting their
right to refuse at any stage (Greener, 2008). Participants will not be harmed in any
manner physically or psychologically and no incentives will be offered to avoid the
bias of respondent. Further, assurance is given concerning anonymity clarifying the
limit and the usage of data which will be used only for only for academic purposes.

Secondary data used for the research are accurately referenced and cited to credit
the original authors.
CHAPTER 04 -FINDING AND ANALYSIS
4.0 Introduction
The indispensable aim of the research was to evaluate the influence of advertising
on consumer brand preference. Consequently, this chapter summarises the author’s
attempt to primary research while evaluating the outcome in order to reveal the
understanding of the related theories and principles. Research results of the
questionnaires were assessed in a coherent manner using quantitative methods
mentioned in chapter 03 with regards to the literature reviewed in Chapter 02.
As Silverman (2011) describes, an appropriate and accurate analysis refers to more
comprehensively simplifying the obstacles associated with a large number of data
whilst restraining the unnecessary efforts of findings and/or comparisons of variables
considered in research. Hence, the data were analyzed using Chi square analysis to
test the link between variables such as advertising and brand equity using SPSS 20
software. Similarly, graphs and pie charts were illustrated using MS Excel by the
researcher to easily demonstrate the research result with percentage values.
Further, inferential analysis is used to test the variables such as antibacterial soap
usage, age, gender, sources of awareness, consumers’ media preference and
attitude towards ad using a descriptive method as Sekaran and Bougie (2011) and
Murray et al. (2001) define that descriptive methods are sensory testing methods
which is ideal when searching for behavioral changes with regard to varied attributes
exploring consumers’ tendencies towards brand preference.
37
4.1 Evaluation of the questions
Table 4.1 - Question 01 Analysis
Main Aim
To indicate the usage of antibacterial soaps
Question Rationale
Do you use Antibacterial Soap? Antibacterial soaps have an emerging
demand among consumers as a hygienic
product preventing illnesses (Lifebuoy,
2015%)
84%
16%
Figure 4.1.1 - Anti-bacterial soaps Users

No
38
The first question in this study sought to determine the usage of anti-bacterial soap
among the consumers in the vicinity of Colombo district. The results of this study
indicate that 84% of consumers are devoted users of anti-bacterial soaps. This
finding was unexpected and suggests that consumers are more focused on
purchasing products which has the higher antimicrobial active ingredients. The
results further confirm the LMRB data that show the highest market share
possessed by Lifebuoy which is 68%. A possible explanation for these results may
be the increased level of awareness, knowledge and exposure gained through
several sources which repeatedly substantiate the importance of using anti-
bacterial soaps than normal regular soaps.
Table 4.2 - Question 02 Analysis
Main Aim
To determine the gender influenced by advertising
Question Rationale
Gender Advertising involves in delivering allied
information about a product or service to
potential consumers affecting their
purchase intention (Hussain et. al., 2008,
p.29; Ntiamoah, Egyiri, and Kwamega,
2014).
39
The second question was to determine the purchasing behavior of consumers’
gender wise. According to the research done considering on similar population of
both sexes, the research findings indicate 52% of male consumers purchase
Antibacterial soaps which is higher than that of females. This suggests the gender
neutrality in the consumption of consumer brands.
Table 4.3 - Question 03 Analysis
Main Aim
To determine the age influenced by advertising
Question Rationale
Age Advertising rarely determine the
purchasing behavior and total advertising
rarely affect the total market size
(Vakratsas and Ambler, 1999).
52%48%
Figure 4.2.1 - Gender

The third question was to determine the age manipulated by purchasing decisions.
As presented in Figure 4.3 that indicates the consumers’ age range in between,
under 20 to over 50. Accordingly, age group 20 – 30 as the most influenced age
group which is 38% of the total sample population. Over 29% of respondents are
from the age range of 31 – 40. The most obvious finding to emerge from the
analysis is that the generation Y and Z’ dominance in the market, which is 67%,
followed by generation x and baby boomers that has taken considerable active
parts which shows 27% of the total population.
Table 4.4 - Question 04 Analysis
Main Aim

Question Rationale
What is your preferred Brand? Brand preference is the consumers’

P.889).
The present study was designed to determine the brand preference of antibacterial
soaps. With respect to the fourth research question, it was found that 43% of total
population prefers the brand Lifebuoy where 36% prefers the brand Dettol. This
seems to be consistent with those of LMRB research which highlights the higher
competition of the industry where lifebuoy being as the market leader in the
antibacterial soap segment and the necessity for rigorous efforts made by the
companies in order to maintain and increase market share.
Table 4.5 - Question 05 Analysis

The fifth question in this study sought to determine the sources of consumer
awareness of the product they prefer. Figure 4.5 above, indicates 70% respondents
were aware of the antibacterial soaps through advertising, whereas 23% from word
of mouth and sales promotion. However, 4% of the population could not remember
how they came across the brand name. These results are consistent with those of
Ayanwale, Alimi and Ayanbimipe (2005) who found advertising as the major
source of consumers’ awareness of the drink Bournvita. This result may be
explained by the fact that businesses investing a higher amount of money on brand
building which was recorded as 34 billion in the first quarter of 2013 (Athukorala,
2013).
Table 4.6 - Question 06 Analysis

Figure 4.6 above indicates 68% of consumers have selected television as their
preferred media followed by Social media, which is 20% of the total population,
especially among the young generation and together 12% for Radio and
Magazines. These results somewhat match those observed in earlier studies of
Ayanwale, Alimi and Ayanbimipe (2005). However, the findings of the current study
do not support the previous research as it shows no evidence of social media which
currently has become a major advertising tool. However, they are consistent with
studies of Kumar and Raju (2013) who found social media plays a major role in the
modern marketing mix. A possible explanation for these results may be the
advancement of the technology and the growing interests of consumers using new
technology.

positive or negative reactions to the
advertisements increase or decrease the
possibilities of uplifting consumers’
purchase intention towards certain brands.
Question 07 was to identify the effect of attitude towards advertising on consumer
brand preference. According to the research findings, it is clear that the majority of
the representative sample has positive attitudes towards antibacterial soap
advertisement. As per the figure 4.7.1 above, 60% of respondent consider
advertisement as appealing, whereas 67% believe advertisements are pleasant.
Further, 57% of respondent are in the opinion that advertisements are high quality.
However, this result has not previously been described. But, it further supports the
idea of Ajzen and Madden (1985, p.454) who recognize the person’s attitude
manipulates the total outcome of his/her responses towards an object.

Brand awareness creates impact on
consumer decision making (Huang and
Sarigöllü, 2012, p.92) by means of higher
recalling or recognizing the brand
ultimately increasing sales (Hoeffler and
Keller (2002, p.79).
The question was to determine the mediating effect of brand awareness towards
consumer preference of antibacterial soaps. Accordingly, a strong relationship
between advertising and brand awareness has been reported in the literature
(Ayanwale, Alimi and Ayanbimipe, 2005). Accordingly, as figure 8.2.1 indicates,
85% of consumers agree with the fact that they purchase their preferred brand
considering the brand name or logo, which represents the brand recall factor and
91% due to brand recognition by means of brand familiarity.
Therefore, in the current study, a significant effect of advertising on consumers’
awareness of antibacterial soap brands can be ascertained as per the Figure 8.2.1
above. The observed relation between advertising and brand awareness might be
explained in this way, brand awareness directly facilitates preference of certain
antibacterial soap brands by consumers’ ability of recalling and recognizing through

could be a major factor, if not the only one, causing brand to be in the consideration
set with raising awareness (Macdonald and Sharp, 2000, p.12; Hoyer and Brown,
1990; Baker et. al., 1986; Nedungadi and Hutchinson, 1985).

To determine the mediating effect of brand image influenced by advertising towards
brand preference
Question Rationale
I purchase my preferred brand of Anti-
bacterial soap due to;
It is categorized as anti-bacterial soap
It is unique
Brand image is a symbol representing a
brand to consumers acting as a
competitive advantage differentiating a
company’s product from those of
competitors which is increased through
continuous advertising (Padgett and Allen,
1997, p.50).
47
The question was to determine the mediating effect of brand image influenced by
advertising towards the preference of antibacterial soaps. According to the figure
4.8.1 above, 73% of the respondent make their purchasing decisions as their
preferred brand’s being categorized as Antibacterial soap where 38% consider the
uniqueness of the product at the brand considering stage. Consequently,
advertising’s creating a significant effect on brand image can be determined
studying the table 4.8.2.3 above. These results further support the idea of Kotler and
Amstrong (1996) and Shimp (1997) as to the purpose of advertising is to increase
brand related stimulation thereby affecting consumer brand preference. There are
several possible explanations for this result which either or may include consumers’
beliefs or attitudes produced over a brand through interpretation, reasoned or
emotional factors (Keegan, Moriarty and Duncan, N.d).

Past experience with brand name
Availability
Product attributes/ benefits
Presentation of information related to a
brand consistently facilitates strong brand
association that occurs with consumers
identification of the need arises through
attributes and benefits they possess
(Keller, 1993).
The question was to identify the mediating effect of brand association. Hence, with
reference to the Table 4.8.3.3 above, it is as certain that there may be a
considerable effect of advertising on brand association due to the fact that, 83% of
respondent consider their preferred brand’s availability, whereas 62% of
respondents believe their purchase intentions are manipulated by the product
attributes and past experience with the brand name. This result further confirms the
literature reviewed on brand association where Keller (1993) explains that brand

Perception of the quality has an effect on
consumer purchase intention (Fornell et
al. (1996), leading to increase success
of the brand, increasing the brand
preference (Allenby and Rossi, 1991;
Chang and Wildt, 1994; Dawar and

The question was to determine the mediating effect of perceived quality influenced
by advertising towards brand preference. As per the table 4.8.4.3 above, where the
data indicates the percentage of each factors’ contribution towards the brand
perefrence, whereas 41% of respondent consider product variety, and 48% judge
packaging attractiveness whereas 59% make their purchase intention based on
the perception of the quality presented through the advertisements. Hence, a
significant relation between advertising and its effect on perceived quality can be
determined relating to the test statistics presented above.
Accordingly, these results confirm the association between quality, packaging and
product variety further supporting the idea of Berger et al. (2007); Holbrook (1992);
Banks (1950); Brown (1958); McDaniel and Baker (1977) and Miaoulis and d'Amato
(1978) presented in the literature review under perceived quality.
Table 4.8.5 - Question 08 Analysis
Main Aim
To indicate the mediating effect of brand loyalty influenced by advertising towards
brand preference
Question Rationale
I purchase my preferred brand of
Antibacterial soap due to;
Overall Quality
Reliability
Cheap alternative brand advertised
Advertising facilitates retaining loyal
consumers and persuade non loyal
consumers’ switching to the advertised
brands (Raj, 1982, p.77). However, Kotler
(1993) is of the opinion that loyalty is
influenced by repeat purchasing.
51
Very little was found in the literature with respect to the research question that is to
determine the mediating effect of brand loyalty affected by advertising towards
consumer brand preference. Consequently, figure 4.8.5 above illustrate the
information related to consumers’ purchase intention of antibacterial soaps. In view
of that, it could be identified that 80% of respondent consider the overall quality of
the brand at the purchasing stage whereas 80% believe in the reliability of the
brand. Moreover, 18% shows the possibility of switching to alternative brands
effected through advertisements.
Considering the above statistics, the researcher identifies the most obvious finding
to emerge from the analysis is the consumers’ tendency towards purchasing their
preferred brand is based on how loyal they are to a particular brand where reliability
and overall quality are significant factors. These results seem to be consistent with
other research which found advertising as an attractive and efficient technique that
can be used to stimulate demand by retaining loyal buyers while facilitating
organizations with reduced switching cost (Shum, 2004, p.241).

Considering the above outcomes obtained after careful review and analysis the data
gathered through 150 respondents, it can be concluded that advertising has a great
impact towards consumer brand preference that has been created through brand
awareness, positive brand images, enhanced brand association, and perceived
quality and brand loyalty among prospective consumers. This will be further
discussed in Chapter 06 under the topic ‘Conclusion and recommendation’.

CHAPTER 06 - CONCLUSION AND RECOMMENDATION
5.0 Introduction
This chapter seeks to illustrate conclusions on the research topic; influence of
advertising on consumer brand preference. Author initiates the study by providing a
brief introduction to the subject where background information, rationale and current
situation of the market segment of Antibacterial soaps are illustrated in detail. The
literature review is presented using secondary sources related to the concerns,
focusing mainly on the aspects of advertising, attitudes towards advertising, brand
equity and brand preference which is elaborated further as a critical discussion
collaborated with respective theories which provide basic knowledge and support to
the research findings.
Further, the researcher has indicated the methods and techniques used in
conducting the research under methodology chapter. Accordingly, research is
reviewed using the data presented in the literature review comparing with the results
of findings and analysis. Recommendations are provided discussing the limitations
of the research.
5.1 Reviews of the research objectives
• To review the literature critically examining the influence of advertising on
consumer brand preference;
• to review the literature critically analyzing advertising and consumer buying
behavior, attitude towards advertising and brand equity;
• to determine the mediating effect of attitudes towards advertising and
advertising and brand equity factors;
54
• to undertake primary research by means of questionnaires to gain quantitative
data related to consumer brand preference;
• to make recommendation analyzing the information based on the theoretical
literature and the practical findings for future improvement of advertising
strategies for anti-bacterial soaps advertisers.
With respect to the above, the first two objectives were successfully achieved
through analyzing several concerned sources and theories of multiple authors
presented through the literature review critically describing the concept of advertising
and consumer behavior, attitudes towards ad and brand equity elaborating its key
aspects refers to as brand awareness, brand image, brand association, perceived
quality and brand loyalty. Accordingly, the researcher identified advertising acts as a
great spur enhancing consumer brand preference.
5.2 Key evidence presented in the literature
5.2.1 Advertising
Advertising is a paid promotional method of communication (Kotler et al., 2014)
consists of verbal, informative, visual and emotional elements (Aaker and
Norris,1982; Rossiter and Percy, 1978; Stern, Krugman and Resni, 1981) used to
enhance brand equity (Sawanth, 2012; Ntiamoah, Egyiri, and Kwamega, 2014)
manipulating consumers’ behavior (Yeshin, 2006; Green, 2012) for positive brand
preference (Barker, 1999).
5.2.3 Attitudes towards ad
Attitude toward the advertising is used to measure the advertising effectiveness
(Brown and Stayman, 1992; Batra and Ray, 1986) which oblige consumers respond
favorably or unfavorably towards a brand (MacKenzie, Lutz and Belch, 1986).
55
5.2.4 Advertising and consumer behavior
Effective advertisements have a great impact on consumers’ purchase intention
(Adelaar et al., 2003) by increasing awareness, attitudes and buying behavior
(Abideen and Saleem, 2011) while stimulating and reinforcing brand equity (Raj,
1982; Malik et al., 2013; Shehzad et al., 2014; Kotler, 2013).
5.2.5 Brand awareness
Advertising increase the level of brand awareness (Yoo, Donthu and Lee, 2000)
leading brand to be in the consideration set of purchase (Macdonald and Sharp,
2000, p.12; Hoyer and Brown, 1990; Baker et. al., 1986; Nedungadi and Hutchinson,
1985) creating a strong effect on consumers’ preference for a repeat purchase
(Macdonald and Sharp, 2000, p.12).
5.2.6 Brand image
Advertising increase brand related stimulation (Padgett and Allen, 1997) through
informing, persuading and reminding (Kotler and Amstrong, 1996; Shimp, 1997)
leading to a higher level of brand image which delineates products from competitive
offers (Padgett and Allen, 1997).
5.2.7 Brand association
Advertising facilitates strong brand association (Huang and Sarigöllü, 2012) that
occurs with consumers identification of the need arises through attributes and
benefits they possess (Keller, 1993) influencing preference (Yoo, Donthu and Lee,
2000).
56
5.2.8 Perceived quality
Effective advertising contributes higher overall perception of quality leading towards
higher perception on brand (Allenby and Rossi, 1991; Chang and Wildt, 1994;
Dawar and Parker, 1994) leading to brand preference (Fornell et al., 1996).
5.2.9 Brand loyalty
Advertising facilitates controlling brand switching behavior (Oliver, 2010) persuading
neutral buyers to switch to the advertised brand (Raj, 1982) and retain loyal
consumers’ drifting to competing brands (Shum, 2004) and persuade repeat
purchasing (Keller, 1993).
5.2.10 Brand Preference
Advertising aid higher brand equity (Donthu, 2000) which increases the level of
brand preference that act as a symbol of status due to consumers’ preference in
purchasing branded items than non branded items (Malik et al., 2013).
5.3 Key findings and analysis
According to the literature reviewed, advertising was found to be the most significant
factor contributing to consumer brand preference as multiple authors have presented
different views and opinions as to how and to what extent advertising can create an
impact on brand preference. However, Secondary data together with primary data
collected using a quantitative method and analyzed through SPSS 20 software
enabled the researcher to identify the third and fourth objectives of the research.
According to the literature reviewed, advertising was found to be the most significant
factor contributing to consumer brand preference as multiple authors have presented
different views and opinions as to how and to what extent advertising can create an
57
impact on brand preference. However, Secondary data together with primary data
collected using a quantitative method and analyzed through SPSS 20 software
enabled the researcher to identify the third and fourth objectives of the research.
Respondents’ demographic profiles were analyzed to identify their attitudes towards
the product. Accordingly, results indicated that age is an imperative factor affecting
purchasing behavior of antibacterial soaps where majority 67% of the respondents
were included in age categories of 20 to 30 and 31 to 40. Further, results indicate
gender neutrality in the purchasing of antibacterial soaps.
The most interesting finding to emerge from the analysis is the consumers’
preference for lifebuoy which resulted 43% confirming several other researches
earlier. However, 36% of respondents’ brand preference of Dettol indicates the
highly aggressive competition among two major brands in increasing market share.
The majority (70%) of respondents’ influenced by advertising to purchase the brand,
whereas 68% selection of television as their preferred media than that of 37%
altogether who preferred social media, radio and magazines indicate the influence of
advertising on purchasing decisions.
Results indicate that the majority of the respondents have favorable attitudes
towards antibacterial soap advertisements which further confirms the findings of
MacKenzie and Lutz (1989); Brown and Stayman (1992) and Batra and Ray (1986)
that recognize attitude towards ad as a mediator influencing brand preference.
Brand equity is directly associated with brand awareness, brand image, brand
association, perceived quality and brand loyalty (Severi and Ling, 2013).
Accordingly, in this study, it could be identified that most of the respondents’
behavior in purchasing their preferred brand is manipulated by advertising strategies
used by organizations in brand building, especially on the physical attributes such as
brand name/ logo, perception of the quality, product attributes and benefits,
58
attractive packaging and categorization of the brand as antibacterial soaps. It could
also be noticed that, reliability and overall quality are the most significant factors
contributing towards brand preference which further confirms the suggestion of
Kotler and Amstrong (1996) and Shimp (1997) that brand related stimulation is
increased with advertising that highly affect consumer brand preference.
5.4 Limitations of the research
The limitation in this research is subject to taken into account when considering the
preparation of the concluding chapter, which is based on three aspects such as
literature review, data collection and variables contemplated. The author’s choice of
the Antibacterial soap market as the study population that consist of existing and
new consumers of different age groups facilitated more reliability and accuracy of
the responses. However, only few variables were measured under the study relating
to brand equity, which means that the value of the brand from consumers’
perception is partially measured as it may include other variables such as
consumers’ purchase intention and the reasons of brand preference that would have
brought the research into a new dimension with remarkable findings.
Further, research outcomes and findings are incompetent in explaining the
possibilities of observed patterns in the study due to the limitations of cross sectional
study (Easterly-Smith, Thorpe and Lowe (2003) and generalizing the outcomes of
this research is ineffectual due to using the convenience sampling technique. Using
quantitative method restricted the research to gather more information which could
enhance the knowledge (Moll et al, 1992).
Recommendations
Appropriate recommendations are given to the issues identified with regard to the
research topic as described in the table 5.5 below.
59
Table 5.5 - Recommendations
Issues identified Recommendations
Cross-sectional analysis may not properly
display the experiential changes in models
and the causality of the brand equity
(Smith et al., 2003).
Longitudinal studies that measure
representative sample population
continuously for a particular period of
time is recommended for future studies
(Burns and Bush, 2003).
Researcher’ selecting convenience
sampling is restricted generalization of the
findings.
The probability sampling technique is
recommended to be used for future
studies to improve and enhance the
validity and generalization of findings.
Researcher’s using only close ended
questions restricted the author gaining
additional information for a more
successful research.
Open and close ended questions can
be used for more meaningful research
(Walliman, 2011; Moll et al., 1992).
