After a long time SEO and Webmaster are waiting for almost a year, Google quality team has recently confirmed that they’re effective working on a real-time Google Penguin major update.
Upcoming update of Google Penguin 4.0 would be superior to Penguin 3.0 Update in 2014 and almost feels like the massive Penguin 2.1 in 2013.
The “real-time feature” hinted that effects of the Penguin algorithmic filter, i.e. demotions and promotions of organic rankings for a website due to link spam (unnatural links) happen faster than in the past. In the past, every Google Penguin update brought drastic changes.
