What Is Keyword Cannibalisation?

Keyword cannibalisation is when several pages on the same site compete for the same query, so none of them ranks as well as one good page would.

In plain English

It usually happens by accident: an article, then a service page, then a landing page, all answering the same question slightly differently over three years.

The search engine has to choose between them, splits the signals across them, and often picks the one you would not have chosen.

What to know

Spot it
In Search Console, look for one query with clicks spread across several URLs, or a ranking URL that keeps swapping.
Consolidate
Merge the best material into one page and redirect the rest to it.
Differentiate
If both pages deserve to exist, change one so it answers a genuinely different question.
Prevent it
Keep a keyword map, and check it before publishing anything new.

Why it matters

Cannibalisation is one of the few SEO problems where the fix reliably produces an immediate improvement, because you are consolidating authority you already have rather than earning new authority.

Common mistakes

×Deleting the weaker page without redirecting it.
×Adding a canonical tag to pages that should have been merged.
×Publishing a second article on a topic already covered, because it feels easier than updating the first.
×Assuming more pages on a subject always means more traffic.

FAQs

How do I decide which page survives?

Usually the one with the links and the better intent match. Move the useful content from the other into it.

Is a canonical tag a fix?

It is a patch. Merging and redirecting is the fix.
