page rank is all useless, there is no use of it for us. Its used by google to prioritize which site to show for any search, it was invented by google founder larry page so the name "page rank". A website with page rank 9 doesn't mean that it will get thousands of visits in a day or page rank 1 doesn't mean that it wont get any hit!
Just Downlod the Google Tool and open the page whihc you need to check Page rank you can see the rank on that page
Larry Page should have stayed in Led Zeppelin, I don’t think this Google thing will ever catch on..
Page rank or Rank page called as any such terminology, is an characteristics of a web page which just considers the important factors of the page such as the content, back links and also the keywords, its density, content and many more. So its just a tool to give a rank to the page but does not helps in getting visitors if you have a good page rank.
