Keyword cannibalization

Keyword cannibalization is an editorial term for pages on one site competing for similar intent and obscuring the most suitable resource.

When pages overlap

One search intent → Page A → Page B → Page C
The issue is unclear ownership of one intent. Sharing a keyword alone does not establish cannibalization.
Text version
  • One search intent
  • Page A
  • Page B
  • Page C

How it works

Check actual queries and page purposes before merging or redirecting.

Example

Example: Two nearly identical services for one audience may need a shared page.

Common mistakes

Two pages sharing a word in their titles are not necessarily a problem.

How can you check this in practice?

Compare pages receiving impressions for the same queries and read their actual content. A problem arises when similar pages serve one task without clear roles. Before merging, check distinct product or informational needs and useful incoming links.

Distinctions and limitations

Two pages sharing a keyword do not establish cannibalization. A shopping category and dictionary definition can serve different tasks. Canonical is for duplicate or very similar versions, not a universal way to choose a “winner”.

Distinct roles for similar pages

“What is ROAS” and “PPC management” can share a term while serving different needs. Two near-identical ROAS definitions have no equivalent justification. Merging should retain useful information and appropriate redirects.

Checking after a change

After editing or merging, check canonical, internal links and the old URL's actual destination. Compare query/page data over comparable periods. One fluctuating position does not prove a resolution or recurrence.
