Keyword cannibalization
When two of your own pages compete for the same keyword, splitting rankings so neither one wins.
In depth
What it really means
Cannibalization happens when several pages on your site target the same keyword and the same intent. Instead of one strong page, you have two or three weaker ones splitting clicks, links and authority, and Google keeps swapping which one it shows.
It is a normal side effect of publishing for years without a keyword map. The fix is almost always consolidation, and the instinct to write a third page about it is the instinct to resist.
How to detect it in Search Console, in five minutes
Open Search Console, Performance, Search results.
Filter to a query you care about.
Switch to the Pages tab with that query filter still applied.
If more than one URL shows impressions for that query, you have overlap.
Check the Average position column over time. If two URLs trade places month to month, that is cannibalization rather than harmless overlap.
The tell is instability, not overlap. Two pages both appearing for a broad term is normal. Two pages alternating in position for the same term is the problem.
Which fix to use
| Situation | Fix |
|---|---|
| Same keyword, same intent, one page clearly stronger | Merge the weaker into the stronger, 301 redirect |
| Same keyword, genuinely different intents | Differentiate the copy and titles, keep both |
| Near-duplicate pages, both weak | Merge both into one new page, redirect both |
| Old page has links, new page has better content | Move the content onto the old URL, redirect the new one |
When overlap is fine
A pillar and a spoke both ranking for a broad term, with the pillar consistently ahead.
A blog post and a product page appearing for a term at different stages of intent.
Category and glossary pages surfacing for the same concept in different formats.
The cost when it is not fine
Split link equity, so neither page reaches the threshold to hold page one.
Diluted engagement signals, since clicks and dwell time land on two URLs.
Wasted crawl budget on large sites.
Confused internal linking, because writers pick whichever URL they remember.
The mistake people make
Deleting the loser instead of merging it. The weaker page usually holds backlinks, and deleting it discards them. Move the useful sections into the winner, then 301 the old URL. Same result, without throwing away authority you already paid for.
Best practices
- Map one target keyword to one page before commissioning anything.
- Audit quarterly using the Search Console method above.
- Merge and redirect rather than delete.
- Point internal links with that anchor at the chosen winner, consistently.
- Differentiate titles and opening paragraphs when two pages must coexist.
- Re-check after any big publishing push or site migration.
FAQs
How do I know if I have cannibalization?
Filter Search Console by query, then look at the Pages tab. Two URLs trading positions month to month is the signal.
How do I fix it?
Usually merge: move the best content into the stronger URL, 301 the other, and repoint internal links.
Is cannibalization always bad?
No. Pages serving genuinely different intents can coexist. It is a problem when they chase the same query and split the result.
Does more content cause it?
Publishing without a keyword map does. Volume is fine when each page owns a distinct keyword and intent.
Can internal links cause cannibalization?
Inconsistent anchor text pointing at different URLs for the same term muddies the signal. Pick a winner and be consistent.
