I'm surprised when look @ webmaster tools Links (1,387,090) my PR is still PR 4 (when I checked it 7 months ago PR 4 ~ 45k backlinks) How can I get too much backlinks?? and why my site doesn't gain PR?? my other sites also have the same PR 0, which they should be at least 3. Google is lazy or they are busy with new ranking method (I heard that they will remove PR soon) ??
PR depended on backlinks several years ago. The PR formula then was : But now PR is more about Traffic, Authority and Age. There are websites with no backlinks yet having PR3, this certainly defies the original PR formula do we know that its not in use any longer. NO one knows Google's current Pagerank formula, but the best thing to do is not concentrate on ranking well and driving more traffic.
It takes into account all internal linking else that number above for my site would be much, much, much lower!
Surprising to me too! Maybe those linking to you are using a nofollow tags, or probably 80% of that sites linking to you have PR 0
