"Google will run listings free on Google Mobile Search pages through November 18"

If you're in mobile marketing, then you should read this article from Enid Burns : "Google Ports AdWords Listings to Its Mobile Search Product" (http://www.clickz.com/3627007) :

"A year after it began testing paid listings on its mobile search product, Google has opened AdWords generally to Google Mobile Search. Keyword management is integrated with the existing AdWords interface, and advertisers will automatically have their listings delivered on the mobile platform unless they request otherwise. 'What's different here is we are taking AdWords text ads, intended for Google.com, and automatically converting them to text ads when a user searches on Google from their mobile device. In this way, advertisers don't need to select a separate mobile campaign, although they still can, but instead can be
connected to potential customers whether they are using Google on their PC or mobile device,' a Google spokesperson said."
