Keyword Cannibalization

Keyword cannibalization occurs when multiple pages on the same website target the same keyword or very similar keywords, causing them to compete against each other in search results. This splits ranking signals — backlinks, clicks, and authority — across multiple pages instead of concentrating them on the strongest single page. Search engines become uncertain about which URL to rank, often surfacing the wrong one.

Common causes include blog posts and product pages inadvertently targeting identical terms, multiple service pages with overlapping keywords, or a content archive that has grown without a clear keyword mapping strategy. Resolution typically involves consolidating redundant pages via 301 redirects, differentiating pages by search intent, or designating one canonical page for each target keyword.
