If you noticed some SERP fluctuation yesterday, It finally looks like it is Penguin. Google says it now will run in Realtime within its core search algorithm. Below is a snippet from Search Engine Land about the latest on Penguin 4.0.
After a nearly two-year wait, Google’s Penguin algorithm has finally been updated again. It’s the fourth major release, making this Penguin 4.0. It’s also the last release of this type, as Google now saysPenguin is a real-time signal processed within its core search algorithm.
Penguin is a filter designed to capture sites that are spamming Google’s search results in ways that Google’s regular spamming systems might not detect. Introduced in 2012, it has operated on a periodic basis.
In other words, the Penguin filter would run and catch sites deemed spammy. Those sites would remain penalised even if they improved and changed until the next time the filter ran,which could take months.
The last Penguin update, Penguin 3.0, happened on October 17, 2014. Any sites hit by it have waited nearly two years for the chance to be free.
Those long delays are now to be a thing of the past, according to Google. With this latest release, Penguin becomes real-time. As Google recrawls and reindexes pages — which happens constantly — those pages will be assessed by the Penguin filter. Pages will be caught and/or freed by Penguin as part of this regular process.
