Heise online, a German IT news portal, just released an article stating that Google is about to extend their AdSense program to support coordinate-based marketing. This step would enable websites presenting spatial information to embed ads which refer to the location a user is currently viewing on the map. Certainly a big improvement compared to the purely keywords-based approach.

I wonder how they are processing the coordinate-information internally. I suppose, they are using a gazetteer to map the coordinates to placenames, which are listed in the keywords. Unfortunately, there is no information on this new AdSense feature on the official Google sites yet - or I did not find them.
