I am seeing very early signs of another possible Google update both based on chatter at the WebmasterWorld
and in other forums and social media spaces. I am also getting private
data shared with me by those who are tracking this closely.
Update: Google tells me this is not Penguin or any spam quality control change.
The
feeling is that Google is testing a new Penguin refresh and that it may
be rolling out slowly. Or that it might be something else. So you
know, we had a Panda 4.0 update last week, and then last weekend (before Panda 4) we had a Spam algorithm update. Prior to that we reported on tons of ranking shifts which Google denied despite all the signs of an update.
