Definition
Link Laundering is a sophisticated black hat SEO technique that involves obscuring the artificial or paid nature of backlinks by routing them through one or more intermediary websites. Similar to financial money laundering, the goal is to make manipulative links appear natural by creating layers of separation between the link buyer and the final backlink. In practice, an operator might pay for a link on a site, which then links to a buffer site, which in turn links to the money site. This creates a chain where the final link appears organic. More complex schemes involve tiered link building where each level of the pyramid uses different link types and sources. Google's algorithms have become increasingly sophisticated at detecting these patterns by analyzing link graph topology, temporal patterns, and content relationships across linked sites. The technique is considered a serious violation of Google's guidelines and can result in severe penalties for all sites involved in the laundering chain.
Key Points
- Disguises artificial or paid links by routing through intermediary sites
- Creates layers of separation to make manipulative links appear natural
- Similar to financial money laundering applied to link building
- Google detects these patterns through link graph analysis and temporal pattern recognition
Practical Examples
Three-tier laundering scheme
A paid link is placed on Site A, which links to a buffer blog on Site B, which finally links to the money site. Each intermediary uses different hosting, content themes, and link types to disguise the chain.
PBN as laundering layer
An operator uses their PBN as a laundering layer: paid guest posts on legitimate sites link to PBN sites, which then link to the money site. The money site's link profile appears clean while benefiting from purchased authority.
Frequently Asked Questions
Google analyzes the entire link graph topology, not just individual links. Patterns like clustered link creation timing, similar content themes across intermediary sites, shared hosting or IP ranges, and unnatural linking patterns between sites in the chain can reveal laundering schemes.
All sites involved in a laundering chain can face penalties: the money site, intermediary buffer sites, and source sites. Penalties range from link equity devaluation to manual actions and complete deindexation for the most egregious cases.
