What is Google Penguin?
Google Penguin was launched in April 2012 to combat link spam and manipulative link building. It specifically targets sites that have acquired links through schemes that violate Google's Webmaster Guidelines, rather than earning them naturally.
What Penguin Targets
- Links from Private Blog Networks (PBNs)
- Purchased links or link exchanges at scale
- Over-optimised anchor text — excessive exact-match anchors
- Links from low-quality, irrelevant sites
- Comment spam and forum link drops
Penguin Today
Penguin was incorporated into Google's core algorithm in September 2016 and now runs in real-time. Instead of penalising entire sites, it devalues individual spammy links. New bad links no longer require a full algorithm update to be caught — they're evaluated continuously.
Recovery
- Identify spammy links via Google Search Console or Ahrefs
- Request removal from the linking sites
- Disavow remaining spammy links via the Google Disavow Tool
- Build natural links to dilute the toxic profile
