As of October 1st, Google’s Gary Illyes has come out to say that the the Panda algorithm, Panda 4.2, is still in the process of rolling out, despite the fact that it began rolling out on July 18, 2015.
Illyes himself had checked out and, indeed, it was still rolling out.
We had a feeling that Panda 4.2 was go roll out very slowly over the course of “several months.” This version of Penguin has only been rolling out for the last three months, so it’ll be no surprise if it’ll take another few months to complete the roll out process.
Illyes add that you can expect it to continue rolling out for some time, as Google announced originally.
