Due to fluctuations in rankings there have been lots of discussions about the latest update of Google’s algorithm, which is also known as Penguin 3.0. According to Google, these fluctuations are to be expected, since the Penguin 3.0 rollout is still ongoing.
Google’s John Mueller revealed, that the Penguin 3.0 roll out may continue indefinitely. On the one hand you can expect websites to recover faster from penalties. On the other hand Google may notice sooner if you are engaged in any kind of blackhat link building. So you might want to keep an eye on where your inbound links are coming from.
