Many experienced advertisers realize that there are many gotchas in the AdWords system...optimization tools and default setting which optimize to boost Google's yield at the expense of unsuspecting advertisers, who don't yet know what match types are or that their ads are syndicated to content sites by default.

To help new advertisers get past many of the gotchas we created the Google AdWords tax calculator - a free utility which highlights many stumbling blocks that catch new AdWords advertisers.

Given that each keyword market is unique it would be impossible to make a tool that was 100% accurate in every situation, but the goal of this tool was to simply highlight common issues, and help new advertisers address them. Individual efficiency gains may be greater or smaller than the rough initial estimates the tool provides.

Please let us know what you think, as we will gladly iterate this calculator to make it better if you have some great ideas you think we should include in it. Like all of Google's products, our calculator is starting out in beta :D
