What is keyword cannibalization?
Keyword cannibalization happens when two or more pages target the same or closely related search intent. This can make your content strategy harder to manage because multiple URLs may appear to compete for the same query.
How this cannibalization checker works
Paste a keyword-to-URL map. The tool normalizes keyword text and groups identical target keywords. It then shows every URL using each repeated keyword so you can review whether the pages should be merged, differentiated, redirected or assigned different search intents.
Important: this is a first-pass check
Repeated keywords do not automatically prove cannibalization. Search intent, page purpose, rankings and actual search results matter. Use the groups as an audit shortlist, then review the pages before making SEO changes.
FAQ
It is a situation where multiple pages on the same site target the same or very similar search intent, which can make it harder to decide which page should rank.
No. Several pages can naturally mention the same broad topic. Cannibalization is more about overlapping search intent and competing pages than simply repeating a word.
Use one page and its primary target keyword per line, separated by a tab or pipe. Exported keyword-to-URL mappings from your SEO workflow work well.
