Few days back I have seen a tool from a famous SEO site.It just look for the quality baclinks and predict the PR.But I think its not completely true !
priya, none of the tool is accurate. If the tools know how google PR is calculated, dont you think they can possible game google? Curiosity kills the cat. Relax and let google do their work.
Don't use such tools, just improve your website, get valuable backlinks and wait the Google updates. Only they know the next PR you will have.
Hehe, sounds like a definition of PR. What is PR? A site measurement purely for entertainment value The art of the game is improving your PR and value is pure entertainment
