Google Launches Real-Time Penguin 4.0: All The Changes & Details

On 23 September 2016, Google finally launched the fourth update of its Penguin ranking algorithm.

Since Penguin 3.0 was rolled out on 17 October 2014, there has been no further update for two years. But finally, Google has updated its Penguin algorithm.  In the official Google Webmasters Central blog, Google said they were in a period of development and testing, preparing Penguin with a number of key updates.

Google said there are two key changes to look out for:
Penguin 4.0 is real-time – unlike the previous versions of Penguin, this update has made Penguin work in real-time, meaning ranking changes brought as a result of the algorithm will be noticeably much quicker after making changes to the site.

It is more granular – Penguin 4.0 devalues spam in a more granular way, by adjusting rankings based on spam signals, rather than the rankings of the whole site.
