Today to my surprise, when I saw Page Rank of my website, I see nothing, it has gone and vanished, Most of the toolsbars showing n/a. When I tried with various PR checker tools, they reported as zero PR. Then I checked PR for other sites including digitalpoint.com I see no PR reflecting in toolbars as well as PRChecker sites telling me its zero. How come all sites gone down to zero PR? I think google has done something interesting(!) with their algorithm? But I am still confused and not understanding where the PR for all sites have gone? does anyone have any idea?
My guess is you are using PageRank checking tools that don't work? http://tools.digitalpoint.com/pagerank.php
Thanks for the tool link. Now I can see PR of all sites intact. I was using toolbars provided by seo quake, quirk etc and sites like prcheck.com, seomoves.org/blog/tools/google-pagerank-checker/ etc. I guess there is a problem with all these sites/tools bars I can see all these still mentioning zero PR e.g prcheck.com/pagerank-check.php?u=forums.digitalpoint.com seomoves.org/blog/tools/google-pagerank-checker/ etc.
