December 8, 2008—On Monday, the Google AdWords team announced that AdWords advertisers can now have the option to display desktop text and image ads on the iPhone , the T-Mobile G1, and other devices that have full HTML Internet browsers. Additionally, advertisers can point to regular desktop landing pages instead of mobile landing pages for their ads. This new feature of AdWords is an additional option.

The Google mobile team recently launched new results pages formatted specifically for the iPhone. So, advertisers can now display ads exclusively on these mobile devices, create campaigns specifically for them, and get separate performance reporting.

It’s a significant new feature of AdWords simply because of the proliferation of high speed Internet-ready phones. Paid ads had been available on the iPhone and G1 already because Google Search on these devices used to show desktop results pages modified for these devices. Advertisers can also choose not to show desktop ads on these devices, or opt out and show ads only on desktop and laptop computers. This will give advertisers more specific targeting options when creating or managing their existing campaigns.

Presently, Google dominates the paid advertising space with an 80% market share. Yahoo is a distant second, and is followed by Microsoft and Ask.
