According to reports Google unveil a beta version of AdSense for Mobile Applications yesterday which allows companies that develop mobile applications that run on devices like Apple’s iPhone and Google’s Android system.

AdSense for Mobile Applications allows developers to integrate AdSense network ads into their mobile applications and to allow advertisers to bid for placement in their apps. Previously, Google AdSense ads showed up only on Web pages rendered by mobile phone browsers

“We are also experimenting with ways to allow advertisers to bid for ad placement on specific applications,” says a Google spokesperson. Google works with application developers to determine the proper signals that help AdSense for Mobile determine the relevance of an ad. The system then matches the signals to relevant advertiser keywords that bid for placement on Google’s Content Network through the AdWords interface.

Now, iPhone and Android application developers can connect their applications with Google’s network. From there, ads appear within the applications and developers earn revenue, similar to regular Web sites displaying Google-brokered ads.
