Google announced on September 23, 2016, that Real-Time Penguin or Penguin 4.0 is now live. The roll out will continue in the coming weeks as Google updates Penguin in various languages.
There are two main takeaways from the update:
The algorithm will be in real-time so that spam results are caught and de-indexed on a continuous basis.
The algorithm is granular, so that instead of a sitewide penalty, specific pages that are spamming, will be devalued in rankings.
