From my observation on the KWs I follow, its seems that on the 26-27 Panda/penalized sites were let back in and then on the 28th the hammer dropped and for 15 on my terms 40-50%(long tails) of the top 100 results were removed. The number is exactly between 40-50%.
I mentioned a while ago something big happened at Google end of July , start of Aug which I bet is the trigger to this latest update. I expect this to lead to an actual bigger update . Somehow everything is tied up to % content x pages x ads x authority and not backlinks, but backlinks at the same time are the main driving force . Have you noticed how strong EMD are these days ? In my view all the talk about quality content is really a big sack of CRAP. My most unoptimized sites rank the best ever with really poor content till my unique high quality content barely makes it.
Moral of the story : content =/= the king , backlinks build in very moderately will win the day . Don't you see it everyone from Google is just spreading propaganda to lead you the wrong way while they try and figure out the mess they created. I am 100% sure all those panda demotions are automatically detected but manually triggered. Just look at the trend it's so obvious. Google is in the weeds.
A lot of people will say yes but after Panda 1.0 I did this and that and gain some traffic back, well you did because your content became better and you attracted more links, not because Google saw your content getting more rich or interesting.
We are just reinventing the wheel all over again but the long way around . Crate a quality content and they will come (says Google) . Well build your damn links and they will come even faster (says me)but really really moderately.
