According to Barry Schwartz of Search Engine Roundtable, Google has confirmed that they have finally released the long-awaited Penguin update over weekend (started rolling out on Friday).
Google originally launched Penguin in April of 2012. It was designed to identify and penalize sites that were acquiring unnatural links – i.e. buying links, link networks, etc – in order to improve their search rankings.
To recover from Penguin, websites that were penalized had to try to identify the bad links, contact the linking site requesting that they remove the link, disavow remaining bad links, then wait for the next Penguin refresh, the last of which was a over a year ago on October 4th, 2013.
Each new update could potentially clear those sites that were previously penalized but have since cleaned up their link profile, and identify and penalize offending sites that have so far escaped the Penguin penalty.
Although we are still awaiting details, it has been expected that this update will allow Google to run more frequent and regular Penguin refreshes like they do with Panda.
