Quick definition

Keyword cannibalization is when several pages on the same site target the same search intent, so they compete for the same queries and search engines alternate between them or rank neither well. It is a diagnosis to confirm with data, not something to assume whenever two pages share a keyword.

Why it matters

When two pages answer the same question, links, clicks and relevance are split between them. The result is often unstable rankings, with the ranking URL switching every few days, and the page you would prefer users to land on ranking lower than a weaker one.

Overlap is not always a problem. A category page and a buying guide can rank for the same query because they serve different intents, and Google sometimes shows two results from one site.

How to diagnose it

  1. In Search Console, filter the Performance report by query and open the Pages tab: several pages with impressions for the same query is the first clue.
  2. Check whether the ranking page changes over time for that query (URL swapping) and whether average position is unstable.
  3. Read the competing pages: do they serve the same intent, or different ones?
  4. Only treat it as cannibalization when the pages serve the same intent and performance is suffering.

Both pages needed, different intentsSharpen each: titles, headings and content aimed at its own intent; link between them

Common mistakes and misconceptions

  • Myth Two pages ranking for the same keyword is always cannibalization.

    In fact Pages with different intents can and should both rank. The problem is two pages doing the same job.

  • Myth Cannibalization is a Google penalty.

    In fact It is a self-inflicted split of signals, not a penalty.
