M6.net Page Rank Checker is a tool that allows you to check the PR of a page or a web site and compare it with the previous PR of the same page. You can enter more than one site or multiple pages of the same site or different ones in one go and let the software check the PR results for it for you. The software automatically remembers the last checked list of sites and displays them along with the PR when you start the software. It also allows you to export the results in a .CSV file so that you can use the results for other purposes. A very useful tool for webmasters for keeping track of PR of a web site.
