Keyword Cannibalization
Keyword cannibalisation is two or more of your own pages competing for the same search intent, so neither ranks as well as a single stronger page would. It is one of the most common self-inflicted SEO problems and one of the few where the fix requires no new writing.

Confirming it, rather than assuming it
- Same intent is the test, not the same keyword. Two pages can share a keyword legitimately if they serve different intents — a definition and a comparison, for instance.
- Check which page actually ranks. If the engine keeps swapping between two of your URLs for one query, that is the signal.
- Look for suppressed pages. A page with impressions but almost no clicks is often losing to a sibling.
- Not every overlap is cannibalisation. A pillar and its clusters share vocabulary by design and should not be merged.
- It is usually created by publishing, not by planning. Two people writing for the same question months apart.
The fixes, in order of preference
| Situation | Fix | Why not delete |
|---|---|---|
| Two pages, same intent, one stronger | Merge into the stronger, redirect the other | The redirect keeps what the weaker earned |
| Two pages, same intent, both weak | Write one good page, redirect both | Two weak pages will not become one strong one |
| Different intents, shared keyword | Leave, and differentiate the titles | They are not competing |
| Pillar and cluster overlap | Leave, and check the internal links | Working as intended |
| Old page outranking the new one | Update the old, do not delete it | It holds the position you want |
How Gixo Quill handles this
This is the specific problem Quill's overlap checker was built for: it compares your published content and surfaces pages targeting the same intent, which is the part that is genuinely hard to spot by eye once a site passes a few dozen pages.
Frequently asked questions
What is keyword cannibalization?
Two or more of your own pages competing for the same search intent, so neither ranks as well as a single stronger page would.
How do I know if I have it?
Watch whether the engine swaps between two of your URLs for one query, and look for pages with impressions but almost no clicks. Sharing a keyword alone is not proof.
Is sharing keywords always cannibalisation?
No. A pillar and its cluster pages share vocabulary by design, and two pages can share a term while serving different intents. Same intent is the test.
Should I delete the losing page?
Merge and redirect instead. A redirect keeps whatever the weaker page earned; deleting discards it and risks a soft 404.
How does cannibalisation happen?
Usually through publishing rather than planning — two people writing for the same question months apart, with nothing checking for the overlap.
