Some people like to calcultate Google Page Rank of their Website. However, it is difficult to find a valuable PageRank Tool. I tried a lot and now, I have 2 main tools in my favorites :

- PR Informer : it calculs the PR of your Website from many Google Datacenters. Thus, you can see if your PR is stable or not.

- Page Rank Checker : just calculate PageRank of 20 Websites at the same time. I have found an other tool which can calculate the PR of 1000 sites together but you have to sign up on this Website and the Tool is not…attractiv !
