Do you develop or publish web-based games? If so, you're contributing to a growing trend - according to comScore, over 25% of Internet users play online games every week, which is over 200 million users worldwide. As a beta user of AdSense for Games, you can display video ads, image ads, or text ads within your online games to earn revenue. You'll be able to show these ads in placements you define, such as interstitial frames before a game, after a level change, or when a game is over. Members of our AdWords team will sell your in-game ad placements directly to top brand advertisers, and you'll also see contextually targeted text and image ads based on content and demographic information. In addition, you'll be able to control the ads you see on your pages using our filtering options.

We've built ad technology for games played within a user's browser, and now we're looking to expand our publisher network. At this time, eligible publishers must have a minimum of 500,000 game plays per day and have 80% of their traffic from the U.S. or the U.K. If you're interested in becoming a AdSense for games beta publisher, feel free to review our complete list of requirements and submit an application. You can also find more information on our games site.
