Keyword Cannibalization

Keyword cannibalization is an informal SEO label for a situation in which multiple URLs on one site overlap in purpose and appear for the same or similar queries in a way that produces an unwanted result. The problem may be an unsuitable page appearing, URLs repeatedly replacing one another, duplicated visitor journeys, or several weak pages where one complete resource would be more useful. Multiple pages earning impressions for the same query is not inherently harmful, and search signals are not automatically “split” whenever topics overlap.

Why it matters: Diagnose an outcome, not a repeated keyword. In Search Console, filter a relevant query or query group and inspect which pages received impressions, clicks, and changing visibility over time; account for canonical URL aggregation, hidden low-volume queries, location, device, and personalised results. Compare each page's audience, task, content, internal links, conversions, and intended role. If two pages serve the same purpose, choose the stronger destination, combine useful material, and redirect a retired URL. Use `rel="canonical"` for duplicate or very similar alternatives that must remain accessible, not as a shortcut for distinct pages. If both pages deserve to exist, make their audience, intent, title, H1, opening copy, examples, and internal-link context meaningfully different. Do not merge pages merely because they share words, and do not create one thin page for every keyword variation. Recheck crawling, canonical selection, search performance, and user outcomes after the change.
