Definition
Google Penguin is a major Google algorithm update deployed in April 2012. It specifically targets sites that manipulate their rankings through artificial link building techniques such as mass link buying, private blog networks (PBNs), excessive link exchanges, or abusive use of over-optimized anchor texts. Since September 2016 (Penguin 4.0), the algorithm runs in real time and now acts at the page level rather than the entire site, devaluing spam links rather than directly penalizing the domain. This evolution has made recovery faster for affected sites.
Key Points
- Targets artificial, purchased, or spam network links
- Runs in real time since Penguin 4.0 in 2016
- Devalues bad links instead of penalizing the entire site
Practical Examples
Artificial link network detected
An e-commerce site that purchased thousands of links with exact match anchors like 'cheap shoes' loses 60% of its rankings after the Penguin rollout.
Successful disavow strategy
A webmaster identifies toxic links via Google Search Console, submits a disavow file, and sees a gradual improvement in rankings.
