What Keyword Cannibalization Matrix does
Keyword cannibalization happens when two pages on the same site end up competing for the same search terms, splitting ranking signals instead of combining them. This tool compares two URLs, extracts their most prominent terms, and flags how much overlap exists between them, so you can see whether two pages are quietly competing with each other.
How to compare two pages
- Enter the full URL of the first page.
- Enter the full URL of the second page.
- Select Compare pages to see a risk summary, each page's top terms, and the terms they share.
Reading the result
A high overlap in top terms, especially combined with similar page titles, is the clearest sign of real cannibalization risk — the two pages are likely targeting the same search intent. A smaller, incidental overlap in shared terms is normal between any two related pages on the same site and isn't necessarily a problem on its own.
What to do about overlap
- Merge the two pages if they genuinely cover the same topic and intent.
- Differentiate them with distinct titles, headings and angles if they should serve different searches.
- Canonicalize or redirect the weaker page to the stronger one if one is clearly the better target.
