Definition
Keyword cannibalization is when several of your pages target the same search intent and compete, so none ranks as well as one strong page would.
Keyword cannibalization explained
It usually happens gradually. A blog publishes a new post on a topic it covered years ago, a service page and a blog post both target the same phrase, or near-identical location or product pages are created at scale. Search engines then have to choose which page to show, and the choice can swap back and forth.
Signs of cannibalization include:
- Two or more of your URLs appearing for the same query in Search Console, with rankings that alternate.
- A page you consider less important ranking instead of the page you want.
- Links and engagement split across several similar pages.
The fix depends on the cause. Merge overlapping content into one stronger page and 301 redirect the others, change the focus of one page to a different intent, or strengthen internal links so it is clear which page is the main one. Not every overlap is a problem: pages that serve different intents can both rank.
Example
Your agency has three blog posts about “local SEO checklist” written in different years, and Search Console shows all three ranking on page two. Merging them into one updated checklist and redirecting the old URLs gives Google one clear page to rank.
Why it matters
Consolidating competing pages is often one of the fastest SEO wins in an audit, because it concentrates links and relevance on one URL.
