When multiple pages on one site compete for the same query, weakening all of them.
Keyword cannibalization happens when two or more pages on the same site target the same or very similar search query. Instead of one strong page, the engine has to choose between several overlapping ones, which can split link equity, confuse relevance signals, and cause your pages to trade positions or under-rank.
It is a self-inflicted problem, common on sites that have published a lot of content over time without a clear structure, and it usually gets worse as the content library grows.
Cannibalization quietly caps your ceiling. Two mediocre pages fighting over one term almost always underperform a single authoritative page. It also dilutes internal links and makes reporting confusing, because the ranking URL keeps switching.
First confirm it is real by checking whether pages genuinely compete for the same intent, not just similar words. Then consolidate or differentiate.
People assume any two pages sharing a keyword are cannibalising, but pages serving genuinely different intents can coexist fine. The real test is whether they compete for the same intent and the same searchers, not whether they share vocabulary.
A content structure where a broad pillar page links to focused cluster pages that link back.
The credibility a site earns with search engines by covering a subject deeply and consistently.
A longer, more specific search query with lower volume but clearer intent and less competition.
