Pay Per Click Competitive Analysis Software

Software tracks the average position and frequency of ad display on Google AdWords by randomly pinging Google. Please note that I do not believe either of these companies have a partnership with Google and if Google detects their ping patterns Google may intentionally offer bad data.

• Ad Archiver - cheap, but not feature rich.
• AdGooroo - more expensive, but shows the data in graphical format.
