The Google Penguin update is an algorithm update from Google that is meant to detect unnatural link profiles and manipulative SEO methods. It was introduced to penalise websites that try to improve their rankings through bought links, spam or other artificial link strategies.
Google Penguin was first released in 2012 and is today part of Google’s core algorithm.
What does Google Penguin assess?
The update focuses mainly on backlinks. Google checks whether links have come about naturally or whether there has been an attempt to influence rankings artificially.
Particularly problematic are:
- bought backlinks
- link networks and link exchanges
- mass spam links
- heavily over-optimised anchor texts
- unnatural link patterns
If Google recognises that a website uses such methods, this can lead to ranking losses.
Why Penguin still matters today
Even though Penguin is no longer released as a separate update, its rules continue to play an important role in modern SEO.
For businesses this means: link building should look natural and be based on high-quality, topically relevant links. Quality is considerably more important than a large number of questionable links.
