What Is Keyword Cannibalisation?
Keyword Cannibalisation is an SEO problem where multiple pages on one website target the same or closely related search query. The pages compete for visibility, clicks and relevance signals, which can make search engines uncertain about the page that best answers the query. The result can be inconsistent rankings and weaker organic performance.

Key Takeaways About Keyword Cannibalisation
- Multiple pages target overlapping search intent.
- Search engines may select the less suitable page.
- It differs from normal internal linking between related pages.
How Keyword Cannibalisation Works

Keyword Cannibalisation develops when separate URLs send similar relevance signals for one search intent. Search engines compare page content, titles, links and user behaviour to decide which URL should appear. If the signals are divided, rankings may move between pages or the chosen result may not match the searcher's needs.

An SEO review compares the target query, page purpose and ranking history for each competing URL. A service page and a detailed guide may support one topic without competing if their intent differs. Clear page roles, distinct titles and deliberate internal links help search engines understand which URL should serve each query.

Expert Note
When we review a website through SEO Consulting, we map target queries against page intent and search performance. We check whether competing URLs need clearer roles, stronger internal linking, content consolidation or a different target query. Our recommendation depends on the pages' purpose and the value each page provides.
