Keyword Cannibalization

When multiple pages on the same site compete for the same keyword, hurting rankings.

Definition

Keyword cannibalization occurs when two or more pages on the same website target the same keyword or very similar keywords, causing them to compete against each other in search results. Rather than one strong, authoritative page ranking well, search engines divide their attention and ranking signals across multiple competing pages — weakening all of them.

Why It Matters

Keyword cannibalization actively harms rankings. Instead of concentrating authority on one definitive page, it splits signals across multiple weaker pages. It confuses search engines about which page to rank and wastes crawl budget on redundant content. Fixing cannibalization is one of the highest-impact technical SEO fixes available.
