Google announced today the availability of AdSense for Mobile, a program that contextually targets ads to mobile website content.

AdSense for Mobile also allows AdSense publishing partners the ability to earn revenue from their mobile websites through the targeted placement of mobile text ads. AdSense for Mobile is intended for AdSense partners who have created websites specifically for mobile browsers, and who want to monetize their mobile content via contextual advertising.

Like Google's other AdSense products, mobile text ads run on an auction model. The system automatically reviews the content of publishers’ mobile websites and delivers text ads that are relevant to the websites’ audience and content. Publishers earn money whenever mobile users click on the ads. AdSense for Mobile is now available to all mobile publishers in 13 countries worldwide.

AdSense for Mobile will be available in the following countries: US, England, France, Italy, Germany, Spain, Ireland, Russia, Netherlands, Australia, India, China, and Japan (available in the coming weeks).
