Another Google update this weekend has been confirmed, but it is a core update, not Penguin.
Almost exactly like the week before, many SEOs and webmasters this weekend reported major ranking changes in Google.
Google was quick to answer that this weekend was the same as last, with ongoing updates to their core algorithm.
Gary Illyes from Google said on Twitter this morning that the weekend fluctuations were "core algorithm" and "not Penguin."
Many webmasters are waiting for a Google Penguin update, and we are expecting it to happen early this year. So when we see major fluctuations, some are quick to say it is Penguin.
