The first page rank of Google was updated like I predicted, but however the next page rank update (Second Page Rank Update: 30th June 2010 – 31st July 2010) was just a minor update which updated the PR (page-rank)of only very less number of websites. Some of the SEO specialist says, PR update will be there for all websites by the end of this month October! Let's wait for the update.
