AdMob Mobile Metrics Report
April 2010

About AdMob
AdMob is one of the world's largest mobile advertising networks, serving billions of mobile banner and text ads a month across a wide range of leading mobile
Web sites and applications. AdMob helps advertisers connect with a relevant audience of consumers on mobile devices and gives publishers the ability to
effectively monetize their mobile traffic. Incorporated in April 2006, AdMob provides the tools, data, and business models fueling the explosive growth of mobile
media in more than 160 countries and territories worldwide.

About AdMob Mobile Metrics
AdMob serves ads for more than 23,000 mobile Web sites and applications around the world. AdMob stores and analyzes the data from every ad request,
impression, and click and uses this to optimize ad matching in its network. AdMob’s monthly report offers a snapshot of its data to provide insight into trends in
the mobile ecosystem.

Methodology
For every ad request AdMob analyzes information available in the user’s mobile browser. From this, AdMob determines device capabilities and more using
open source tools and a variety of proprietary techniques. The result is a snapshot of the devices viewing the more than 10 billion monthly ad requests and
impressions that flow through AdMob’s network. We believe this data will be valuable in identifying and tracking trends, evaluating market readiness and more.
AdMob also serves mobile ads into iPhone and Android applications. The traffic from these applications is included in the Metrics report.


There is no standard industry definition of a smartphone. AdMob's definition is based on Wikipedia: "A smartphone is a phone that runs complete operating
system software providing a standardized interface and platform for application developers" (http://en.wikipedia.org/wiki/Smartphone). AdMob classifies a phone
as a smartphone when it has an identifiable operating system and we continually update our list as new phones enter the market. Despite running the iPhone
OS, the iPod touch is not a phone, and thus not considered a smartphone based on this definition.

Limits of this Data
Representativeness - AdMob does not claim that this information will be necessarily representative of the mobile Web as a whole or of any particular country-
market. AdMob’s traffic is driven by publisher relationships and may be influenced accordingly. Because the data is pulled across ads served on more than
23,000 sites and applications, we feel the data will be useful and may help inform business decision making.

Ad Request Classification - For some handsets and operator networks, it is difficult to collect full handset data. AdMob categorizes these requests as
"unclassified" and does not serve targeted ads to these requests.

  • 13. AdMob Mobile Metrics Report April 2010 About AdMob AdMob is one of the world's largest mobile advertising networks, serving billions of mobile banner and text ads a month across a wide range of leading mobile Web sites and applications. AdMob helps advertisers connect with a relevant audience of consumers on mobile devices and gives publishers the ability to effectively monetize their mobile traffic. Incorporated in April 2006, AdMob provides the tools, data, and business models fueling the explosive growth of mobile media in more than 160 countries and territories worldwide. About AdMob Mobile Metrics AdMob serves ads for more than 23,000 mobile Web sites and applications around the world. AdMob stores and analyzes the data from every ad request, impression, and click and uses this to optimize ad matching in its network. AdMob’s monthly report offers a snapshot of its data to provide insight into trends in the mobile ecosystem. Methodology For every ad request AdMob analyzes information available in the user’s mobile browser. From this, AdMob determines device capabilities and more using open source tools and a variety of proprietary techniques. The result is a snapshot of the devices viewing the more than 10 billion monthly ad requests and impressions that flow through AdMob’s network. We believe this data will be valuable in identifying and tracking trends, evaluating market readiness and more. AdMob also serves mobile ads into iPhone and Android applications. The traffic from these applications is included in the Metrics report. There is no standard industry definition of a smartphone. AdMob's definition is based on Wikipedia: "A smartphone is a phone that runs complete operating system software providing a standardized interface and platform for application developers" (http://en.wikipedia.org/wiki/Smartphone). AdMob classifies a phone as a smartphone when it has an identifiable operating system and we continually update our list as new phones enter the market. Despite running the iPhone OS, the iPod touch is not a phone, and thus not considered a smartphone based on this definition. Limits of this Data Representativeness - AdMob does not claim that this information will be necessarily representative of the mobile Web as a whole or of any particular country- market. AdMob’s traffic is driven by publisher relationships and may be influenced accordingly. Because the data is pulled across ads served on more than 23,000 sites and applications, we feel the data will be useful and may help inform business decision making. Ad Request Classification - For some handsets and operator networks, it is difficult to collect full handset data. AdMob categorizes these requests as "unclassified" and does not serve targeted ads to these requests.
