What is Anchor text checker?
Anchor Text Diversity Analyzer — Free anchor text checker 2026: measure exact-match ratio, Shannon entropy and anchor-type mix with risk flags. — paste anchors, get your report.
Anchor texts are normalized (lowercased, whitespace collapsed) and grouped. Exact-match ratio is the largest group's share; entropy is Shannon entropy in bits over the groups. Type labels are our own editorial heuristics, not Google-published rules: naked-url (the text is a URL), generic (one of 28 fixed English phrases like "click here"), exact-match (the most-used text, used 2+ times), partial (everything else). Risk thresholds are editorial: ≥50% concentration, entropy under 1.0 bit, naked-URL or generic share over 30%.

Good to know
- Type labels and risk thresholds are our own editorial heuristics — they are not Google-published rules and must not be read as SEO advice from Google.
- "Exact-match" here means the single most-used anchor text in your list; the tool has no target-keyword input, so it cannot know your intended keyword.
- The generic-phrase bank is English-only (28 phrases); non-English generic anchors will be labeled partial.
How it works
Anchor texts are normalized (lowercased, whitespace collapsed) and grouped. Exact-match ratio is the largest group's share; entropy is Shannon entropy in bits over the groups. Type labels are our own editorial heuristics, not Google-published rules: naked-url (the text is a URL), generic (one of 28 fixed English phrases like "click here"), exact-match (the most-used text, used 2+ times), partial (everything else). Risk thresholds are editorial: ≥50% concentration, entropy under 1.0 bit, naked-URL or generic share over 30%.
Examples
Four unique anchors — high entropy, no risk flags.
75% exact-match ratio — triggers the over-concentration flag.
