If you're a small business that focuses your offerings and services on a particular area, there's a good chance that you've done at least a little bit of playing around with the local search options offered by Google AdWords. If so, you may be interested to know that David Wallace covers the launch of a new AdWords tool that allows you to preview your geographically targeted ads so that you know they really are showing up in the regions that you are targeting.

From David's blog:

The search results and ads are not active, so you can preview at will without accruing impressions or accidental clicks. Best of all, you can refine the results page by adding location attributes and values manually to the URL of the ad preview page. Optional attributes include a target country, longitude/latitude coordinates, regions, and cities. In the U.S., you can also set a target ZIP code or designated market area (DMA).
