Google announced a new campaign-level option that allows those of you who are AdWords advertisers to show your desktop text and image ads on the iPhone, the T-Mobile G1, and other mobile devices with full (HTML) Internet browsers. The ads can point to desktop landing pages so you don't need to create mobile landing pages or ads in mobile formats. The ads will have many of the same benefits as the standard mobile ads, such as the delivery of mobile-specific calls-to-action and reaching mobile users that are searching with their phones more than ever -- especially during the holiday season.
To target ads for G1 and iPhone, go to your campaign settings tab in your AdWords account. Then for the "Device Platform" option under "Networks and Bidding," select "iPhones and other mobile devices with full internet browsers." As additional devices that use full browsers enter the market, your ads will show on those phones, too. You can visit the AdWords Help Center for more detailed instructions and watch my video below for a quick demo.
