From the Google Inside Adwords Blog announcement:
Today, we’re announcing a new campaign-level option that allows you to extend the reach of your text and image ads to show your AdWords ads on the T-Mobile G1, the iPhone, and other mobile devices that have full (HTML) Internet browsers. This new option will now allow you to display your ads specifically on these devices, create exclusive campaigns for them, and get separate performance reporting. We hope this option will help you more effectively reach your audience with the right message at the right time.
Users are performing a lot of searches on these devices, and searches are likely to go up during the holiday season. Last Christmas, the iPhone drove more traffic to Google.com worldwide than any other mobile platform.
Unlike standard mobile ads, you don’t need to format your ads for mobile phones to show your ads on the G1 and iPhone. Because the G1 and iPhone have full Internet browsers, you’ll be able to display your standard AdWords ads and landing pages on these devices without having to modify them.
Now that Google is ever more actively becoming part of the mobile advertising game for the Mobile Web, I am pretty certain we will see a far greater increase — more so than up to now — in the upcoming months. So, look out for Google ( — not like you didn’t know this already, but I thought I’d just try to be funny!)
