All signs are pointing to a Google update being pushed out yesterday afternoon into today. The speculation across the SEO forums is that this is the Panda refresh we were expecting to see this weekend.
Google's Matt Cutts said we should expect to see a refresh of Panda sometime this Friday or Monday. It seems like the Panda update started actually yesterday afternoon and is continuing to propagate throughout now.
The ongoing WebmasterWorld thread has dozens of SEOs and Webmasters claiming rank changes for better or worse. Here are some examples:
Is there an update happening? we're down maybe 40% or so since few hours ago.
Im seeing some movement for my main keyword, go Panda go.
I'm seeing signs of a Panda update here in the UK. Or Panda everflux. That's going to kill the update talk somewhat isn't it...
I've also received several emails and comments about a possible Google Panda update.
Google has not yet confirmed this update, nor do I expect them to confirm it since Matt Cutts also said that the future Panda updates will be more rolling updates.
This may be the last manual Panda refresh we report - Panda #25 - welcome.

Google Won't Confirm or Deny: I received word back from Google that since future updates will be rolling updates, Google is unlikely, going forward to confirm or deny Panda refreshes. I have a more detailed story on that over here.

Yes I think the update is very much in progress, I have been observing some severe ranking fluctuations since last night (Indian time)

I don't see anything with top keywords happening. People could just be getting drunk early.

We've been steady all week. Almost identical numbers each day, which is uncommon. But nothing drastic or too, too crazy... Keeping the fingers crossed.

to those guys who arent seeing anything, it means u don't receive enough traffic. I for instance receive 41k per day. and can see fluctuations. you guys who get 50 hits a day, don't even bother

wow - I still feel that I cannot really tell fluctuations with my 3 million impressions per day. There are so many other things than Google. Holidays, carnival, Easter, sports ...

Waiting from long time for it, Already i am facing problems in my keywords ranking need to update to new strategies from panda update.

Yup, another inexplicable penalty, with some of the lowest search traffic in a couple of years. To think I actually had hopes that Panda might push us up rather than down. After being hit three times last year, I didn't think another search degrade was actually possible.

I saw a small movement today, not sure if it was affected by the update or not since it only a bit higher than the normal increment path.

The only noticeable thing for me is that sites that were blitz in the very first panda update have started to come back. From nowhere to page 14 of the most competitive phrase in our industry. That is so far, if it really is an update.

Got a little hit by the last update. Couple pages were on first pages, and not they are 2nd or 3rd. But the strangest thing is all content is 100% unique, I add new articles on daily basis, all is fresh, authentic and I only have 1 small adsense ad. Go figure whats wrong.. Thanks for the post!
