We reported about a possible Google update around February 13th and I do believe there was something rather large on that date – but now there is more chatter about a possible update early this week, this past Sunday and Monday at Google.

The ongoing WebmasterWorld thread has a lot of discussion from webmasters about a possible update. Here are some recent comments:

Now, some of the tracking tools show higher than normal activity on those days including Mozcast and Algoroo but SERPs.com and SERP Metrics seem pretty flat.

Did you notice ranking changes and referral changes from Google earlier this week?
