Real-Time Bidding, or RTB, is sure to be one o the most

requently used online advertising buzzwords o 2010. Many

advertising experts have argued that it is going to undamentally

change the course o online advertising as we know it. It has even

been re erred to as the next revolution in advertising or the bene ts

it will provide to all players in the ecosystemthe publisher, the user,

and the advertiser.

Real-time bidding allows advertisers to reach the right user, in the

right place, at the right timeand assign an individual value to a

particular ad impression. Leveraging advanced technology o ered

by a relatively small but quickly growing number o companies,

advertisers place bids on reaching speci c users dynamically, and

on an impressionby-impression basis.

PubMatic has ound that publishers monetizing ad inventory via RTB

can receive an increased eCPM because o the improved campaign

per ormance that RTB o ers. In the case o one particular US

Entertainment publisher, the publisher was able to achieve a 106%

increase in eCPM over a six-month period.

Executive Summary:RTB From The Publisher Perspective

8/6/2019 PubMatic RTB White Paper

5/40

P M c 2010 5

Along with the clear bene ts o RTB, publishers must be cognizant

o the potential pit alls associated with this emerging media buying

trend. RTB was originally conceived as an advertiser- ocused

solution, and publishers must take multiple issues into account in

order to make their businesses success ul in an RTB-enabled world.

PubMatic estimates that less than 1% o online advertising was

purchased via RTB in 2009, and that will grow to 3-5% in 2010.Because RTB is the astest growing segment o US online advertising,

its imperative that publishers understand the RTB landscape and

how to success ully harness RTB ad dollars to their bene t.

Along with the clearbene ts o RTB,publishers must becognizant o the potentialpit alls associated withthis emerging mediabuying trend.

The most important promise that RTB holds or publishers is

increasing the value o ad impressions. With RTB, advertisers

have the greatest level o transparency available on the individual

user in real-time, which can signi cantly increase the value o

each ad impression and the corresponding publisher CPM.

Having greater transparency about the user in real-time provides

great insight to advertisers, but it is the di erence in how media

is bought and sold with real-time bidding that is the true game

changer.

Currently, most digital media buying is done based on assumptions

about certain audiences. For example, audiences bought through ad

networks and ad exchanges are o ten purchased in buckets or by

segment. How the audiences are categorized in certain segments

depends on who is selling them. And while some audience sellers

do a better job o segmenting users than others, so long asindividual impressions are being grouped into a bucket and sold at

a pre-negotiated price, they are not being airly valued and are o ten

sold at under-valued prices, as shown.So long as the individualimpressions are beinggrouped into a bucketand sold at a pre-negotiated price, theyare not being airly

valued.

In Example 1 , a luxury car advertiser is looking or a very speci c

audience type and is willing to pay a premium price to reach a

speci c user that is highly quali ed. The more quali ed the use, the

more the advertiser is willing to pay. On the right side o the example

below, the advertiser (or rather the technology company placing

bids on behal o the advertiser) can see unique characteristics

about the user and there ore is willing to pay a $3.90 CPM to target

that user.

On the le t hand side, the same user would have been bucketed into

an auto-buying segment and priced according to the segment price,which is ar lower than what was paid via RTB or the individual.

Example 2 below shows the ongoing luxury car ad campaign on a

larger scale. Because RTB is conducted in real-time, advertisers,

or their proxy vendor that acilitates their media buying, can buy

impressions to reach speci c users or reject them as the campaign

is in progress. There ore, in a real-time situation the luxury car

advertiser would likely choose to reach many o the same users

that would have been segmented or them as auto buyers in a pre-

negotiated bucket buy. However, having more in ormation about

each individual user, the advertiser would also likely want to reach

users that didnt all into the pre-de ned auto buyer segment while

also rejecting some o the impressions that would have made itinto the segment. More importantly, the pricing would be di erent

based on the unique characteristics o each user as opposed to an

average across the segment.

In the long run, advertisers that have better per orming campaigns

can pay more to target the right users. According to Turn, a

company that acilitates RTB transactions or advertisers by

leveraging inventory rom sell-side plat orms such as PubMatic,

advertisers are seeing up to 135% improvement on click-through

rates and 150% improvement on conversion rates.

Better per orming campaigns have a positive impact on all parties

involved, not just or the advertiser. Below are a ew key bene ts that

RTB brings to the publisher, the user, and the advertiser.

Real-time bidding is very much still in its in ancy, but the

number o companies that help advertisers and publishers

leverage RTB is growing rapidly. In 2008, the number o

companies talking about RTB could be counted on one

hand. In 2009, the number o companies involved in real-

time bidding increased dramatically, but each category in the

RTB ecosystem plays a signi cant role and it is important or

publishers to understand those roles.

RTB Role

Agency buying desks generally serve as the

liaison between the advertiser or parent agencyand the plat orms they use to acilitate real-time bidding. For example, an agency buyingdesk may work with a DSP to acilitate an RTBcampaign.

RTB Technology

Agency buying desks do not have core RTBtechnology to acilitate campaigns in real-time or that they use a 3rd party company,usually a DSP. However, some enable buyers,through a single inter ace, to procure inventory

rom many sources, add layers o advertiserand 3rd party data, and manage targeting, andanalytics.

A truly competitive bidding environment is essential or ensuring

consistent and continuous revenue growth. PubMatic has seen

signi cant eCPM improvements or its publishers that are

participating in RTB campaigns, but because this is a bidding

environment, a high price is not guaranteed. RTB is still in its

in ancy, and the number o RTB advertisers is relatively small,

so without enough advertisers competing to reach the same

user, a lucky advertiser could get the ad space or below

market value.

When advertisers nd the user they want to reach, they are willing

to pay a high price to reach that userbut they still want to pay the

least amount possible in order to reach that user. PubMatics Ad

Auction Engine does not allow any real-time bids to win an auction

unless the bid is high enough, as shown in Example 3.

Example 3: The Ad Auction Engine Process Works For Every Impression

An RTB bid only wins if it beats the pricing coming from PubMatics Ad Price Prediction anddirect sold insertion orders that a publishers direct sales team entered into PubMatics system.

In this example, the real-time bid of $3.05 bid did not win. Instead a non-RTB enabled ad

network was willing to pay the most for the ad space.

Due to the act that there are ar ewer RTB enabled demand

partners than non-RTB ad networks and exchanges, in most cases

an RTB bidder is not selected to serve an advertisement. In the

cases where there are no RTB bidders competing or the publisher

impression, PubMatic selects the highest paying ad network or

exchange using the proprietary Ad Price Prediction process, or

chooses to show an ad rom a direct sold insertion order i it is the

highest priced ad available.

The Ad Price Prediction process is power ul technology that was

developed over the course o several years by PubMatics 40+ ulltime engineers. Download the white paper dedicated to Ad Price

Prediction to learn more, which can be ound at http://www.

PubMatic.com/technology/whitepapers .

The majority o RTB transactions that PubMatic acilitates on

behal o the publisher are received rom companies that have their

own campaign optimizing algorithms working the bene t o the

advertiser. For example, when a DSP is working on behal o anadvertiser, the DSP continually adjusts its pricing during the course

o the campaign in order to reach the right audience at the lowest

cost to the advertiser. However, PubMatics Ad Auction Engine

keeps ad prices high or the publisher by bringing together the

greatest number o demand sources or each impression, and as a

result, real-time bidders o ten have to increase their bids i they are

to win the impressions they want.

Ensuring RTB DataSa ety And BrandProtection

Real-time bidding has the potential to bring signi cant

revenue li t to publishers, but RTB is not without its own

brand control and data sa ety risks. Publishers need to

understand that RTB was originally developed or the bene t

o the advertiser, and there ore publishers should consider

an RTB partner that is a strict publisher advocate and has

the tools to protect the publisher.

8/6/2019 PubMatic RTB White Paper

29/40

P M c 2010 29

There are ve key considerations that publishers should be thinking

about when selecting a partner or RTB:

Getting The Right Demand Partners From The Start1

Prevents Most Hassles

As most publishers know, not every ad network or advertiser iswell intentioned. A strict RTB partner vetting process should berequired based on the objectives o the publisher.

A publishers RTB sell side partner should en orce demandpartners and advertisers to:

Meet the minimum RTB technical requirements or ad

speed and data sa ety so that latency and brand control isnot a problem

Actively bid on the RTB plat orm and meet a minimum

number o bid wins each month to ensure that no datasquatters on the plat orm

Comply with regular auditing o data that is collected vs.

dollars spent on bidding

PubMatic, or example, has set up a strict Trusted PartnerProgram or RTB and will proactively remove demand partnersthat do not meet the high expectations set in the agreement.

The Publisher Should Set The Rules Around What Data Is2

Passed And Have A Way To En orce Those Rules

The publisher owns their own data and publishers needthe ability to set rules around which data they pass to aspeci c bidder. In some cases ad networks or other demandpartners will try to collect more in ormation than is needed

or the campaign. Publishers should have a way o protectingthemselves rom data the t.

For example, Data Firewall , is a proprietary product developedby PubMatic that:.

Gives publisher total transparency about what data is beingpassed

Identi es pixels and tracks i ad network or advertiser is

putting pixel on publishers without permission

Automatically alerts a publisher when demand partners go

beyond normal targeting

Screening Ads In Real-Time Process Helps Prevent3

Unwanted Ads

Ensuring creative control can be di cult. A publishers sellside plat orm partner should have a creative screening o alladvertiser creative on the publishers site available to view inreal-time. Ideally, the sell side plat orm has this process builtinto their UI so that when the publisher logs in they can see thecreative that is being shown on their site at that moment.

In order to provide the publisher with a snapshot o what adsare going across their site, or sites, at any given moment,PubMatic o ers publishers a Live Creative Dashboard that:

Takes regular screen shots o publisher website in 5-60

minute intervals

Emails screen shots to PubMatics Creative Services Team

Traces URLs re erred to during ad serving

Reduces manual work o reloading ad tags or checking

Preventing Unwanted Malware Is Key to A Good User4

Experience

For the most part, RTB advertisers do not use malware simplybecause the cost o RTB campaigns are too expensive to wasteon such advertising. However, it can happen and an extrasa ety net should be available to ensure that publishers havemaximum sa ety.

There are now products available or publishers that:

Automatically scans all ad tags

Proactively and quickly identi y any potential malware

Alert the publisher i there is a security breach

Send an email detailing ad calls + URL/Ad Network

mapping

Publishers have the option o using the products themselves orpartnering with a sell side plat orm such as PubMatic that has itbuilt in as part o the service.

Loading Speed Should Never Be An Issue5

Part o a good user experience is ast loading pages. A globaldata center ootprint ensures that demand partners return bidsin milliseconds to ensure positive end-user experience.

Publishers may consider asking their partner about the locationo data centers, and ask about:

Speed delivery times

How o ten the speed time is monitored

Whether or not a third party company veri es the

speed time

I advertisers want real-time bidding, publishers should think

about real-time selling. And in 2010, we will see more publishers

dipping their toes into the RTB pool as they realize its potential to

connect them to more great brand advertisers and the opportunity

to improve eCPMs or their valuable audiences as well as or their

harder to sell inventory.

While a hand ul o media companies have shut out ad networks orreplaced third parties with homegrown networks, many success ul

publisherswith great brands, experienced ad sellers and the latest

technologystill struggle to ll 50% or more o their inventory.

We have a very high touch sales organization, an executive o

one major publisher says, and there has tended to be a bias

against networks and exchanges. In spite o intense debate in the

company, they have committed to testing. Some o our inventory is

currently biddable on exchanges through our optimizer, and were

excited about introducing RTB, he says, adding that early tests

seem promising.

He urges publishers to catalog and share successes and best

practices. Every publisher should be testing and getting ready or

the day when RTB will become the norm. Otherwise, even now,youre just leaving money on the table.

On the buy side, Anthony Rhind, Co-CEO, Havas Digital, recently

told CMO.com, Buying at the impression level, as opposed to the

placement level, allows segmentation strategies to be executed with

greatly reduced waste. O course, segmentation must be in ormed,

so with impression buying comes the need to use data to pro le

impressions to realize that segmentation. This is where the usion

o contact/customer data with campaign data, site data and pro le

data becomes critical to directing trading strategies. This is an

extremely exciting area or our industry, with major implications or

our ability to drive clients business volumes that are attributed to

digital media.

As RTB continues to grow, publishers may earn more or their

inventory while also gaining insights into their audiences value

that was previously available primarily to the networks. Adding up

the possibilities, there may be good reason to expect a ve- old

increase in RTB volume this year. As PubMatics co ounder & CEO

Rajeev Goel cautions, Real-time bidding is still in its in ancy, but it

is gaining momentum every day. Publishers cant a ord to stay on

the sidelines and let somebody else gure it out and take home the

growing tide o RTB advertising dollars.
