Since the launch of Windows Phone 7 last year, app developers have been monetizing their Windows Phone 7 apps with the Microsoft Advertising Ad SDK for Windows Phone 7, which is powered by the industry’s first, real-time bidded Mobile Ad Exchange. The SDK is designed to maximize in-app advertising revenue by empowering multiple ad networks to bid on mobile inventory at the exact moment when an impression is served, increasing yield and reducing waste.
To demonstrate the monitization effectivness of the Microsoft Advertising Ad SDK for Windows Phone 7, Microsoft worked with two Windows Phone Developers to see which advertising platform helped them make more money with their apps … Microsoft Advertising or Google’s AdMob.
Herm Mogilevskiy, developer of the “Paper Toss” app, and Jeff Weber, the developer for the “Krashlander” app, implemented the Microsoft Advertising SDK for Windows Phone 7 and Google’s AdMob Windows Phone 7 Ad SDK on a 50/50 rotation in both of their apps to see which one would provide a higher advertising yield. From June 2nd to June 20th these two apps made nearly 2.33 MM total ad requests split between Microsoft’s Windows Phone 7 Ad SDK for Mobile and Google’s AdMob Windows Phone 7 Ad SDK.

During this period, the Microsoft Advertising SDK for Windows Phone 7 drove a 71% higher yield, producing greater overall gross revenue earnings and fill rate.
While these results are very encouraging, we’re really just getting started in building out what we believe will prove to be the world’s most advanced monetization engine for mobile apps. We’ve got some exciting news coming in the next few months on the international front, so stay tuned to this blog for the latest on the Microsoft Advertising SDK for Windows Phone 7.
“Paper Toss” for Windows Phone 7

With over 222K downloads to date, Paper Toss is an innovative game that lets users challenge their skill by tossing paper balls into a trash can while watching the fan try to blow their shot off course.
Herm integrated the Windows Phone and AdMob ad control into his ad supported Paper Toss app, allocated 50% of the inventory to each network, and then watched as the two in-app advertising solutions competed head-to-head to drive revenue.
In the words of the Developer
“Owning my own app development company keeps me on my toes about platform fragmentation and app monetization opportunities. I was interested in testing the two leading in-app ad solutions for Windows Phone 7 and was impressed by Microsoft’s performance. At a 50/50 test, Microsoft Windows Phone 7 Ad SDK outperformed in every single metric... delivering higher yield and fill rate than from AdMob” – Herm Mogilevskiy, Developer of “Paper Toss” for Windows Phone 7
“Krashlander” for Windows Phone 7
With over 231K downloads to date, Krashlander made its debut in the Windows Phone marketplace on February 23rd, 2011 and challenges users to catapult a stick man in a “krash-suit with skis” while taking down all the robots in their way.
Jeff also integrated the Windows Phone and AdMob ad control into his ad supported Krashlander app, allocating 50% of the inventory to each ad network, and then waited while the ad units competed head-to-head to drive revenue.
In the words of the Developer
“Developing apps has been a passion of mine for some time now and the ability to make money doing what I love is very important. This test indicates to me that not only is the Windows Phone 7 Ad SDK less buggy than AdMob’s Windows Phone SDK, it also earns me several times the revenue over equal time periods.” – Jeff Weber, Developer of “Krashlander” for Windows Phone 7
