In case you missed it, Matt Cutts announced an update to the Penguin Algo on Friday. Nothing major it seems, only impacting 0.1% of English language searches (so if you are part of that 0.1%, congratulations you win a t-shirt).
It’s interesting for a number of of other reasons though. As Barry Schwartz ponted out, all the speculation that that updates were occurring since the Penguin update was first rolled out were wrong! It also highlights that for all those naive enough to think that this was the last of the spam attacks and were counting there lucky stars because their sites are still ranking… I reckon it’s only a matter of time.
