Few days back i was telling some1 regarding PR, google pR is 9, twitter pr is 10, facebook pr is 9 and so on, but later i checked they all showing PR 0 and today i just check ur reply so i got to know that there is no PR factor now, if you know, Can you please share why google stop it, and what are the basis for now other then alexa rank.
Google has stopped updating the page rank, as it has removed the tradition of page ranking. You can check any website it will show 0 rank only. So no need to worry about page rank.
