A new site was released the other day named GoogSpy which boosts of being a "Adwords Competitor Research" tool. I did a search on rustybrick and then clicked on the rustybrick.com result on the left under companies. This tool informed me that I rank #3 for "dynamic web sites", #9 for "pagerank" and #10 for "web development services" and "web definitions". I am sure I rank well for other competitive terms, or maybe not. But it is clear that I do bid on AdWords for rustybrick, see my AdWords Ad on the right. So it seems that currently the GoogSpy still needs some more development and testing.
However, the press release does boast of being able to easily figure out what ones competitors are bidding on at AdWords. "It also displays the search terms that they naturally rank in the top ten and it even computes the company's top 25 competitors."
