Rule reference

Content rule

Near-duplicate content

Blockednear_duplicate

Two or more planned pages have substantially similar body text.

Last updated

Trigger

When this rule appears

Verified body-text similarity reaches the configured near-duplicate threshold (default 0.85).

Coverage

What this check can and cannot guarantee

Coverage depends on how the pair is discovered. Identical fingerprints and pages in the same template family are compared exhaustively at the 0.85 threshold. Across different template families, candidate banding guarantees discovery only from about 0.891 similarity upward; pairs between 0.85 and 0.891 may still be found, but are not guaranteed to be compared.

Why it matters

Decide what changes next

Read this finding as evidence about the affected page, not as a verdict on the whole site. A Review finding needs a decision; a Blocked finding should be addressed before the page moves forward. Coverage findings mean the check is incomplete, not that the page passed.

Next action

How to resolve it

Merge redundant pages or rewrite them around genuinely different user needs and evidence.
