Keyword Cannibalization

When multiple pages on your own site compete for the same keyword, splitting ranking power and confusing search engines.

Keyword cannibalization occurs when two or more pages on your domain target the same keyword. Google may alternate which page it ranks (causing ranking instability), split link equity between the competing pages, or rank neither page as well as it would a single consolidated page. The result: weaker rankings for all competing pages.

Common causes: blog posts and product/service pages targeting the same keyword, pillar pages and cluster posts with the same focus, multiple similar products with near-identical pages, and regional pages targeting the same keyword without hreflang differentiation.

Fixes: consolidate the competing pages into one comprehensive page (301 redirect the others), differentiate by intent (one page for informational, one for transactional), use canonical tags to specify the preferred version, or add noindex to secondary pages. Use the Keyword Cannibalization Checker to identify competing pages before they cost you rankings.
