Keyword Cannibalization

Keyword cannibalization happens when two or more pages on your own site target the same query and end up competing with each other. Instead of one strong page ranking well, you get several weaker pages splitting the signals — and Google unsure which to show.

Diagnose it in Search Console: look for a single query where the ranking URL keeps flip-flopping between pages, or several pages each ranking low for the same term. The fix depends on intent — consolidate genuinely overlapping pages into one (redirecting the loser), or differentiate them if they actually serve distinct intents. Prevention lives in your keyword-to-page mapping: one primary intent per URL.

At scale, cannibalization is a symptom of missing content governance, not an isolated bug. Senior practitioners build a keyword-to-URL map as the source of truth, run periodic cannibalization audits, and make consolidation part of a pruning strategy that concentrates authority rather than scattering it. The judgement call is consolidate-versus-differentiate, and it hinges on whether the intents are truly the same.
