Keyword cannibalization occurs when pages overlap so strongly in intent that search systems receive unclear signals about the best page to show.

What it means
The issue is not repeated words; it is pages answering the same task without a distinct audience, format or scope.
Related pages can coexist when their intents are genuinely different.
How to assess it
Compare query clusters, titles, headings, main content, canonicals, anchors and landing pages receiving impressions.
Practical workflow
- Define the user task and the set in scope.
- Compare query clusters, titles, headings, main content, canonicals, anchors and landing pages receiving impressions.
- Choose the smallest reversible change.
- Merge near-duplicates, differentiate separate intents, or retire a redundant URL with an appropriate mapping.
- Re-check the rendered outcome and preserve the measurement scope and date.
Concrete example and verification
For example, two guides may both target the same purchase question: one is a broad category guide and the other is a comparison with no distinct criterion. Compare their actual query set, content promise and internal anchors. If the comparison cannot stand alone, fold its useful evidence into the category guide; if it can, define the comparison’s decision rule and make the difference visible in titles, headings and copy.
Limits and common mistakes
Redirecting without checking distinct user tasks can remove useful coverage.
