Advertisers who operate a site that caters to local areas or specific regions in the USA, customized targeting is the solution to market their products/services to a very specific locations that can be predefined. This customized, laser targeting of your prospects ensures that you don’t blow your marketing budget on poor leads and in areas that your local business cannot service. You end up only targeting areas which you serve. For example, if you ran a pizza joint in your town and only have 2 outlets serving the immediate metropolitan area, you wouldn’t want to place Adwords ads for the entire state. Doing so is wasteful.
The solution? Google combined two technologies it developed to accomplish this advertising goal. Google Adwords using Google Maps makes it a cinch to define the area in which you want your ads to show.
First you set the center of your custom area. You then set the advertising distance (the radius of the circle) in miles or kilometers. The AdWords system will translate searchers’ locations into latitude and longitude coordinates and determine whether they fall into your target region.
