Mobile applications are now big businesses, but the developers behind them are forced to spend more of their time dealing with increasing complexity. They need to develop for different devices with different screen sizes, choose from a myriad of advertising networks, and manage varying rich media ad creative formats.

The new Google AdMob SDK 6.0 release for Android and iOS is designed to reduce the complexity that app devs are managing, freeing them up to focus on continuing to grow their great app into a great app business. With AdMob SDK 6.0, app developers can:

Use multiple ad networks
We recognize that many app devs work with several ad networks to maximize fill rates, and ultimately, revenue. AdMob SDK 6.0 makes it easier to do this with our free AdMob Ad Network Mediation solution which allows app developers to allocate inventory across many top 3rd party ad networks on a country-by-country basis. App devs will retain full control and choice over the ad networks they use with a single UI that features the best-in-class AdMob reporting. For more information on AdMob Ad Network mediation, visit the AdMob Help Center.

Get banner ads to be smart, regardless of screen size
New mobile device screen sizes pop up every day, but app developers shouldn’t have to worry about how banner ads will appear on different devices. AdMob SDK 6.0 eliminates this issue with the introduction of new banner ad formats that automatically expand to the full width of any smartphone screen, even in landscape mode. To learn how to implement these new banners, visit the AdMob Developer Site.

Serve more rich media ads
The lack of industry standards for mobile rich media ads has been a barrier for advertisers and made it challenging to app devs to run more of these engaging ads in their apps. The new AdMob SDK 6.0 is compliant with Mobile Rich Media Ad Interface Definitions (MRAID), a common API for mobile rich media ads running in mobile apps. This is a big step forward in reducing complexity as it establishes a standardized set of commands for developers creating rich media ads. It also means that advertisers will be able to build mobile rich media ads that can be served across networks regardless of device platform, application or technology used to display the media.

As we announced several weeks ago, the iOS version of the Google AdMob SDK no longer uses the universal device identifier (UDID). We are working toward a long-term solution that will benefit users, app developers and advertisers.
