Ads in a flip

After a year in beta, Google has opened AdWords to its Mobile Search product.

Keyword management will be integrated into the existing AdWords user interface. Ads will appear in the mobile platform unless advertisers actively decide not to participate, reports ClickZ.

Mobile Search listings will be free until November 18. After November 19, AdWords users must opt out, or they will be charged for mobile clicks.

However, Google notified AdWords users that only ads with mobile-adaptable landing pages will qualify for inclusion in Mobile Search.
