Several weeks after Google optimized its search results for the iPhone, the search giant has announced it has tweaked its AdWords platform to better support the newest breed of mobile phones such as the Apple iPhone and T-Mobile G1 – as well as other phone browsers that can display full HTML. Google already has a mobile-specific ad service but the key here is that customers won’t have to reformat their ads for each platform, instead running a single campaign across all Internet-enabled devices.

Clients can analyze the results on either platforms to determine where their ads are receiving the most or best response. This may not provide an immediate, huge boost to Google, especially with the looming economic slowdown. However, it could position them as one of the easy choices in a mobile advertising space that is expected to skyrocket in the coming years as more people access the web from their smartphones.
