It looks like Google did another PageRank update yesterday and I notice a jump in PR for this Web Marketing blog. I also noticed a few of my internal pages have got an increase in Page Rank.
Google seems to be increasing its frequency of PR updated, there has been about three to four PR updates this year. The last one was about six week ago.
With an increase in PR for this blog, Google seems to have changed its algo with this update as I noticed some SERPs move to the second page on Google.
Did you notice the update for your website ?
