Who Is Using Your Client's Name as an Adword on Google

GoogSpy is a new tool that reveals what adwords companies are purchasing in Google. Search for your or your client’s name or product names to see who is using them as adwords. Or, enter in a competitor’s name to learn what adwords they have purchased.
