Keyword Cannibalization
Keyword cannibalization is when two or more pages on the same site compete for the same search, which splits their strength so that neither ranks as well as one combined page would. It is a content architecture problem rather than a technical one, and it is usually created by publishing several similar articles on a topic over time without checking what already exists.
The symptom is a set of pages that each rank moderately for the same query, often trading places between checks, while none reaches the top few results. Search Console shows this clearly when the same query returns impressions for several of a site's own URLs.
The resolution depends on the pages. Two genuinely similar pages are usually best merged into one stronger page, with the weaker address redirected to the survivor. Two pages that serve different intents, one explaining a topic and one selling a service, are usually best kept and differentiated, so each targets the wording its own audience uses.
Prevention is cheaper than repair: before writing a new page, search the site for the query it targets and confirm nothing already answers it.
Why it matters
Publishing more articles on a topic a site already covers can lower its rankings rather than raise them.
