Keyword Cannibalization: How to Detect and Fix It

Keyword cannibalization happens when two or more pages target the same query. Instead of one strong contender, Google splits authority between them and ranks neither well.

Detection: Search Console Pages report

Filter by query in the Performance report. If two URLs show impressions for the same head term, you have cannibalization. Sort by impressions desc to find the worst offenders first.

Fix 1: Merge and 301

Combine the two pages into one stronger asset. 301 the loser to the winner. Preserves backlinks, consolidates authority.

Fix 2: Differentiate intent

If both pages have unique value, retarget one. 'Best running shoes' (commercial) vs 'How to choose running shoes' (informational). Update titles, H1s, and internal anchor text.

Fix 3: Canonical the weaker page

Use rel='canonical' to point the weaker page at the winner. Loses some link equity but is faster than rewriting content.
