Penguin update is one of Google’s very noticeable changes to its algorithm. It was launched in April 2012, with an aim to pick up sites considered to be spamming its outputs. As Google always is concerned about quality, Penguin update was introduced to prevent activities like keywords stuffing and cloaking which violate and manipulate Google’s quality guidelines in order to have better rankings.
Penguin update operates at intervals, and it finds out and penalizes sites, for violating Google’s guidelines. An auxiliary document with the list of penalties is available on Google. Time span between updates and penalties remain frozen until a new update happens. Even if issues are corrected, the penalty is carried forward until the next Penguin update takes place.
Google’s announcement of the Penguin update topped a common question in everybody’s mind as to “How soon could they recover? Gary Illyes from Google confirms that the wait will not be too long, he also states” Penguin recoveries are happening now and will be finished within the next few days.” So if a website was hit by the Penguin update in the past, and if necessary steps towards recovery were executed, there are chances of citing improvement this week. But one thing is for sure, that getting rid of penalties will only reduce the bad link pointing to the site. It will nowhere automatically boost the sites ranking. If at all in the past two years, time has been invested trying getting rid of the links, a slight rank adjustment can be seen. But if efforts have been made in removing bad links while acquiring good new links, in this case a more significant rank adjustment will be visible.
Hence, this update gives an overview about how the eradication of penalties from sites will impact ranking.
