Keyword Cannibalization
In one line
Keyword cannibalization happens when multiple pages on the same site target the same query and end up competing with each other, dragging all of their rankings down.
Going deeper
Cannibalization usually happens by accident. As blog content piles up around a topic, you eventually have three to five pages chasing nearly the same query. Google can't decide which one to rank, and all of them slip.
Detection is straightforward. In Search Console, watch for multiple URLs surfacing for the same query, or run a 'site:example.com keyword' check and see whether several near-duplicate posts come up.
Fixes generally fall into three buckets: 301 redirect the weaker pages into the strongest one, merge them into a single super-guide, or split intent cleanly and re-target each page to a different angle.
