Page Rank History Checker
Checking the Page Rank history of a site can be very useful since it can give you hints about the age of the site and the most important, it can show if the site was penalized by Google at some point. Generally if PR was higher than 0, and then dropped to 0, it’s very likely site was penalized. Another case is if PR drops 2 units or more. The best tool to check for PR history is URL Trends. Simply enter the URL in the search box, then push Site Rankings.
