FREE BACKLINK AUDIT
TOXIC LINKS + COMPETITOR GAP

When you run /seo backlinks, Claude SEO detects which data sources are available, queries each one in parallel, and merges results with confidence-weighted scoring. Anonymous sources (Common Crawl + verify crawler) work out of the box. Free authenticated sources (Moz, Bing Webmaster) require one-time setup. The DataForSEO extension is optional and adds live commercial-grade depth.

The output is a 7-section report: profile overview, anchor text distribution, referring domain quality, toxic links, top pages, competitor gap, and new or lost links. Each section labels its data source so you know whether a finding is from Moz, Bing, Common Crawl, DataForSEO, or the verify crawler. A 0-100 health score sums up the profile.

Health Score Weighting

The backlink health score uses seven factors and applies source-confidence weighting:

• Referring domain count: 20%
• Domain quality distribution: 20%
• Anchor text naturalness: 15%
• Toxic link ratio: 20%
• Link velocity trend: 10%
• Follow-to-nofollow ratio: 5%
• Geographic relevance: 10%

A numeric score is produced only when at least 4 of the 7 factors have data. Missing weights are redistributed proportionally. With fewer than 4 factors, the report says INSUFFICIENT DATA and shows only the available factor results, sources, and confidence levels.

How should you review toxic-link findings?

A toxic-link flag is a prompt for manual review, not proof that a domain should be disavowed. Start by confirming that the linking page exists, that the link points to the expected destination, and that the pattern is not a legitimate editorial mention. Compare the source across available indexes because backlink databases differ in coverage and freshness. Google's spam policies define link spam and the behaviors its systems evaluate. Google's separate disavow links guidance says the tool is advanced and should be used with caution. Claude SEO therefore writes a reviewable file and never uploads it automatically. Keep links that are relevant or naturally earned, investigate uncertain domains, and reserve removal or disavow actions for links you have verified as manipulative or connected to a manual action. Record the evidence behind every final decision.
