Glenn Gabe says, “Penguin 3.0 was one of the most anticipated algorithm updates in recent years when it rolled out on October 17, 2014. Penguin hadn’t run for over a year at that point, and there were many webmasters sitting in Penguin limbo waiting for recovery. They had cleaned up their link profiles, disavowed what they could, and were simply waiting for the next update or refresh. Unfortunately, Google was wrestling with the algo internally and over twelve months passed without an update.

So when Pierre Far finally announced Penguin 3.0 a few days later on October 21, a few things stood out. First, this was not a new algorithm like Gary Illyes had explained it would be at SMX East. It was a refresh and underscored the potential problems Google was battling with Penguin (cough, negative SEO)”.
