Well, the idea is… there are several ‘root’ webpages that have a high pageRank (which is a number ranged from 0 to 10), and there is a formula to calculate the pagerank of a page.. based on the pagerank of the backlinks. It’s a graph.. and the pageRank flows from those ‘root webpages’.
So… this chrome plugin will help you check, seamlessly, the PR of any website you’re currently viewing. Why would you need that?. Simply curiosity… or SEO purposes. Of course!
