Google rolled out their latest version of Panda that has been named version 4.0 on 20th May 2014. As this update has had a number increase (from 3.xx to 4.0) which means it’s likely there have been some major changes. It is also likely that there has been a data refresh. If your website was affected by previous versions of panda but you have “cleaned up” any previous issues you should see your sites rankings return to “normal” after a data refresh.
On the 4th October Matt Cutts, head of Google’s webspam team, confirmed that Google rolls out Penguin 2.1, (a.k.a. Penguin 5).
Although Google are giving nothing away, by calling it Penguin 2.1 they have sent out the message that there are no major changes to Penguin 2.0, just an update of current algorithm. Unlike when the last update when Google specifically named the update 2.0 to show a departure from the original Penguin.
However although the change may not be earth shattering it is having a “noticeable” effect on 1% of search results. This may not sound like a lot but it is in the SEO world and as Troy Reddington pointed out, we in the SEO industry are pretty observant!
