Keyword Cannibalisation Checker

Keyword cannibalisation happens when two or more of your own pages target the same search, so they compete with each other and neither ranks as well as one strong page would. Paste the keyword each page targets (from your content plan or a Search Console export) to see where pages overlap.

Free, no sign-up. Runs in your browser: nothing you enter is stored or sent to us.

Your keyword map

Comma or tab separated. Paste straight from a spreadsheet. Add a third column with clicks or impressions to see which page is stronger. Up to 5,000 rows.

How overlaps are found

  1. Normalise keywords. In normal mode, case and punctuation are ignored, simple plurals are reduced (“plumbers” → “plumber”), filler words such as “in”, “for”, “the”, “near” and “best” are removed, and the remaining words are sorted. So “emergency plumbers in Leeds” and “Leeds emergency plumber” become the same keyword group.
  2. Normalise URLs. Domains, trailing slashes, query strings and case are ignored, so the same page written two ways is not flagged.
  3. Group and flag. Any keyword group mapped to two or more different URLs is a conflict. Pages mapped to many unrelated keyword groups are flagged as unfocused.

If you include a third column (clicks or impressions), the page with the higher figure in each conflict is suggested as the one to keep as the main target.

What to do about a conflict

SituationUsual fix
Two pages say almost the same thingMerge the content into the stronger page and 301 redirect the weaker one
Pages serve different intents (a service page and a how-to article)Re-focus each on its own intent and link from the article to the service page
Location pages overlap with the main service pageMake each location page genuinely local, or consolidate (see the Location Page Planner)
The weaker page has value for users but not searchKeep it, re-target it, and use internal links to point to the main page

Check redirects you create with the Redirect Map Validator.

Limits

This tool compares the plan you paste. It cannot see which pages Google actually ranks for each search. In Search Console, open Performance, filter by a query, and look at the Pages tab: if several of your URLs share clicks for one query over time, that confirms the overlap.
