How to check keyword cannibalization using Search Console data?
Hey everyone!
Keyword cannibalization can easily hide real traffic potential. When many pages on your site rank for the same keyword, Google may not understand which page is the main one. As a result, impressions and clicks are split across multiple URLs, and your strongest page doesn’t receive the visibility it deserves.
Within GSC Insights, we utilize a report that helps us quickly identify these cases.
Here is how it works:
1/ Keywords are sorted by how many pages rank for them.
Some keywords have 20-80+ pages of competing content.
2/ Click the number of pages to see every URL with impressions, clicks, CTR and position.
For example, the keyword “site checker” shows 61 URLs, which already signals confusion.
3/ Top Page Impressions % is one of the most helpful signals.
If the top page has a low share, Google splits impressions, a strong sign of real cannibalization.
4/ Click any page to open all its keywords and metrics instantly, and return without reloading.
5/ If you have an international website, you may see different language versions ranking for the same English keyword. This is normal, and you can use the country filter to review these cases clearly.
What additional filters or metrics would you add to enhance the cannibalization report?
