U.S. Scorecard for Mobile Advertising Reach and Targeting (S.M.A.R.T.™)

June 2010 S.M.A.R.T.™ Highlights

Millennial Media’s U.S. Mobile Landscape

The U.S. Mobile Web increased by approximately 3%, from 75.3M to 77.4M users.

Millennial Media’s U.S. unique audience reach increased by 2% in May, from 61.5M to 62.9M unique users month-over-month to a continued industry-leading 81% reach of the Mobile Web (according to Nielsen).

Hispanic and Black multi-cultural audiences continue to lead in mobile data usage according to a recent study by the Pew Internet & American Life Foundation. Our June rankings of the Top U.S. Mobile DMA’s echo those findings as many of the top DMA’s represent locations comprised of high multi-cultural populations. Brands interested in reaching multi-cultural audiences should make mobile an integral part of their marketing plans.Source: e-Marketer, Blacks, Hispanics Continue to Lead in Mobile Data Usage, Pew Internet & American Life Foundation, July 12, 2010

Spotlight on the Entertainment Ad Vertical

Our special section this month looks at the Entertainment vertical in greater detail. Advertisers in this space are highly innovative and consistently lead the way in driving new mobile advertising ideas.

A 300% increase in DVD release campaigns since Q2 2009 signaled recognition by movie studios that mobile advertising can be used to effectively drive results across all product release windows, i.e., Motion Picture Release, DVD Release, VOD, etc.

Movie studios use the highly-effective Audience Takeover targeting strategy to achieve 100% share of voice with audiences to drive ticket sales on premiere weekends. Automotive and Telecom verticals should leverage this technique to promote new car and product launches.

Q2 Vertical Snapshot

Portals & Directories ranked number one for the third consecutive quarter. We anticipate continued heavy investment in this vertical as top brands compete to become the “go-to” portal with mobile consumers.

(Data compiled from 6/1/10 to 6/30/10)

Telecom moved into the number two position this quarter. See the special feature in our May 2010 S.M.A.R.T.™ report for more on how Telecom advertisers used sophisticated, consumer-focused targeting strategies in their mobile campaigns.

Retail & Restaurants climbed three places to the number seven position in Q2. Growth in this vertical was driven by retailers building databases for re-targeting, featuring location-based couponing for summer sales, and ramping up spending for early back-to-school campaigns.

Automotive advertisers spent aggressively on mobile campaigns in Q2, jumping back into the top 10 this quarter, displacing the Pharmaceuticals vertical.

Engagement & Targeting

Expand Rich Media increased 3% to represent 6% of the Campaign Destination Mix in June. Automotive brands, like Entertainment advertisers, are designing rich media elements in their campaigns that are unique to mobile – not just re-purposed creative from the Wired Web.

Submit Form and Retail Promotion were among the top-performing post-click actions in the MYDAS™ Portfolio Mix in June. Tourism, airline and hotel advertisers within the Travel vertical actively engaged consumers with free trip promotions and special offers that captured the attention of summer vacationers making their travel plans.

As an ever-increasing trend, advertisers are leveraging Audience-Targeted campaigns on Millennial Media’s network. The unique attributes of Mobile allow for this refined Audience Targeting. In June, 41% of campaigns leveraged this method.

GEO targeting accounted for 56% of the Targeted Audience Mix in June. This targeted reach method continues to resonate strongly with advertisers in the Travel vertical, particularly Hotels and Resorts, who are able to reach visitors new to the area with relevant messages.

Entertainment has placed in the Top 3 Mobile Advertising Verticals on Millennial Media’s network consecutively for the last 12 months. There has been tremendous growth and diversification in this ad vertical as brands have embraced mobile to successfully promote a variety of entertainment products including CDs, Theatrical Movie Releases, DVDs, Television and Cable Programs and Games.

Movie studios use the highly-effective Audience Takeover targeting strategy to achieve 100% share of voice with audiences to drive ticket sales on premiere weekends. Automotive and Telecom verticals should leverage this technique to promote new car and product launches (Chart A).

Advertisers within Entertainment are savvy mobile marketers – especially when it comes to the use of consumer-focused targeting strategies. Brands often utilize Millennial Media’s unique ability to develop custom audiences (e.g., horror movie enthusiasts, romantic comedy fans). Additionally, they re-target based on previous campaign results, to achieve higher consumer engagement rates (Chart A).

Spotlight on the Entertainment Ad Vertical JUNE 2010

Entertainment brands (particularly Movie Studios and Music Labels) work collaboratively with Millennial Media’s in-house creative team to develop best-in-class creative with rich media, innovative apps, games, videos and music streaming components. Health & Fitness, Automotive, Travel, Telecom, CPG and a number of other verticals should use this innovative approach to enhance their current campaigns.

Nielsen Reach Methodology & Disclaimer: Nielsen Mobile, a service of The Nielsen Company, is the world’s largest independent provider of syndicated consumer research to the telecom and mobile media markets. Nielsen Mobile focuses exclusively on tracking the behavior, attitudes and experiences of mobile consumers. Their reports also provide up to seven years of data on internet, video, gaming, audio and advertising trends for mobile phone users. Mobile user behavior information is derived from general U.S. population samples under established and accepted rules. For more information, please visit www.nielsenmobile.com. Disclaimer for ‘Custom Roll-up”: This report is produced for the convenience of Nielsen clients requiring alternative aggregations of audience traffic. These custom roll-ups are user-defined and subject to redefinition and renaming upon client request and may be changed or restated at any point in time. Clients may use the data contained within these custom roll-ups to illustrate their unique business models or partnering relationships for internal analysis. Public use of this data must clearly state that this is nonstandard aggregation (”Source: Nielsen, Custom User-Defined Report, <Date>”) and cannot be compared to other custom reports or the syndicated reports on a rankings basis, including category level rankings. Nielsen does not allow for the double counting of traffic. Nielsen makes no claim as to the correctness of the custom aggregations but does certify the measurement traffic data as accurate.

Millennial Media Methodology:Network reach is calculated from the count of unique users across our entire network. Millennial Media uses proprietary techniques to uniquely identify at least 75% of our user base persistently across our network and tracks the unique reach over the course of the month-long period. For the remainder, the unique user data is used to calculate the average frequency of views that a user consumes in a month. We apply that average frequency to the remaining impressions to determine our network-wide reach. Data provided is derived from Millennial Media server log activity for the time period indicated. Cost Per Engaged User (CPEU™) averages overall campaign spend against the number of unique users who engaged with the campaign creative. CPEU is derived by applying the overall media spend to the total number of users that engaged in any one of the actions which campaigns provided, such as expanding a rich media creative, visiting a landing page, watching a video, etc.
