What is keyword cannibalisation?
Also known as: keyword cannibalization, content cannibalisation
Keyword cannibalisation: Keyword cannibalisation happens when two or more pages on the same site target the same search intent, so they compete with each other and search engines struggle to choose which one to show. It often results in neither page performing as well as one strong page would.
Why does it matter?
Signals such as links and engagement get split across near-duplicate pages, and the ranking page can swap back and forth, making performance unstable.
For AI search it muddies the answer. If two of your pages give slightly different answers to the same question, it's less clear which one represents your position, and both may look weaker than a single definitive page.
How do you act on it?
- In Search Console, look for queries where several of your URLs receive impressions, especially where the ranking URL changes over time.
- Decide whether the pages truly serve different intents. If they do, sharpen each one's focus; if not, merge them.
- When merging, move the best content into one page, redirect the other, and update internal links.
- Before publishing anything new, check whether an existing page already covers the intent.
Where FindContentGaps helps
FindContentGaps flags cannibalisation from your Search Console data, and its auto-QC gate checks new drafts for cannibalisation against your existing content before a human reviews them.
Frequently asked questions
Is it cannibalisation if two pages rank for the same keyword?
Not always. If both rank well and serve different intents, such as a product page and a how-to guide, that can be fine. It's a problem when pages chase the same intent and hold each other back.
Should I delete cannibalising pages?
Rarely outright. Merging the useful content into the stronger page and redirecting the weaker one generally keeps its value, while deleting without a redirect throws it away.
