Link scheme

A link scheme is Google's term for manipulative linking intended to game ranking. Official guidance covers buying or selling links that pass PageRank-like signals, excessive link exchanges, large-scale article marketing with keyword anchors, and similar patterns.

Why it matters

Schemes put participating sites at risk of ranking demotion or manual actions. Even when you did not buy the links, scheme-like spam in your profile can require triage so you know whether you are looking at marketing residue, a vendor mistake, or a negative SEO dump.

Cleanup should start with stopping bad acquisition, requesting removals, and only then considering a carefully edited disavow file. Google emphasizes that most sites never need to disavow.

How it shows up in a scan

Scans do not declare "link scheme" as a legal finding. They surface spam-flagged referring domains and patterns that often overlap with scheme inventory:

• Paid or network blogs with repeated commercial anchors.
• Sitewide footer and sidebar placements across thin hosts.
• Sudden bursts of low-quality referring domains.
• Scraped or farm pages built only to link out.

Not every partnership link is a scheme. Problem patterns are scale, payment for ranking signals, deception, and irrelevance. When your own team bought links in the past, stop the program, clean what you control, and be cautious about disavowing third-party domains you barely understand.

For inbound spam that only looks scheme-like, keep the bar high. Map each cluster to published policy language, attempt removals where contacts exist, and leave uncertain hosts out of any draft file. The toxic backlink checker helps you build that candidate list without treating every flag as proof of a scheme.
