It looks like Google has been busy this quarter. For the second time in the fourth quarter of 2011, there is a PageRank update. A PageRank update is currently in progress, as reported in the Google forums on DigitalPoint.com.
We’ve confirmed this PageRank update based on the fact that RankChecker.com is now PageRank 4 (was PageRank 3 before today).
Thank you, Google!
