Are you a webmaster using the Google Maps API to create some of the cool customized maps or showoff specific places in various city maps? If so, you may be able to integrate advertisements - and your AdSense publisher ID - into your Google maps, meaning you could earn money if any of your visitors click on one of the ads displayed on the maps.

So how exactly would this work? Quite easily, actually. Publishers would not have to go and tag other locations of interest in hopes that there might be an advertisement associated with it. Instead, Google would automate the system of adding AdSense ads to the map.

This would mean that in addition to the points you are displaying on the Google map, Google would also add and display other paid for points of interest on the map. If a visitor moused-over one and then clicked on the displayed AdWords advertisement, they would receive revenue off of each of those clicks… just how Google AdSense currently displays ads that publishers earna portion of the revenue on when the ad is clicked.

When could this possibly be released? Google is not announcing that, at least not yet, according to Andrew Eland, the Google software developer who talked about the program at the Developers Day. But very likely, surfers could see some AdSense beta testers using this new feature on some of the customized Google maps out there in the near future, so keep your eyes open.
