Previously, Google has only allowed users to target customers in specific countries + territories or cities + regions. By adding Google Maps to the mix,
, AdWords now allows users to target potential customers at a granular level.
By selecting customized targeting, users a prompted to enter a physical address or select a point on a map and then define a coverage radius. Advanced users can even define a coverage area by plotting 3 or more points on the map.
Here's me using this new feature to target Central Australia by constructing a polygonal area from 4 points (I'm sure there's a demand for Vioxx in the Outback).
Too bad you can only have one polygon per adgroup. If you want to target two or more hotspots in the same city, you'll have to create a new campaign. Otherwise, this another great way for AdWords to reach businesses looking at localized adserving.
