Google Penguin 4.0 rolling out is bigger than Penguin 3.0
After waiting for almost a year, Google has confirmed that they’re working on a real-time Google Penguin update.
Google Penguin 4.0 seems to be bigger than Penguin 3.0 Update in 2014 and almost feels like the massive Penguin 2.1 in 2013.
The “real-time feature” implies 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.
