Keyword Cannibalisation Checker
Paste your pages with the keyword each one targets. The checker lists keywords claimed by more than one page, even when the words are in a different order.
Separate the address and keyword with a comma, tab or bar. Addresses are compared without the www, the trailing slash and the # part.
Worked examples
Reordered words
https://ex.com/standing-desks/, standing desk https://ex.com/blog/desk-guide/, desk standing
1 keyword with a clash: standing desk / desk standing is used by 2 pages.
The words are the same in a different order, so the pages compete.
About Keyword Cannibalisation Checker
Keyword cannibalisation happens when two or more pages on one site aim at the same search. The pages then compete with each other, so search engines may swap between them, show the weaker one or treat neither as the clear answer. It tends to build up slowly, as a site publishes more and more articles about the same subject without checking what already exists.
Paste a list of your pages with the main keyword for each. The checker treats "standing desk" and "desk standing" as the same phrase, ignores plurals and small joining words, and lists every keyword that appears against more than one page. It also lists pages that carry six or more keywords, which are often too broad to rank for any of them. The result is a short list of pages to merge, retarget or link together.
How to use Keyword Cannibalisation Checker
- Export your pages and their main target keyword from your plan or your analytics.
- Paste them with the address first, then a comma, then the keyword, one pair per line.
- Read the list of keywords with a clash and the pages that share each one.
- Decide for each clash whether to merge the pages, change one target or link from one to the other.
Common uses
- Auditing a blog that has grown over several years
- Planning a content clean-up before a redesign
- Checking a new article does not overlap an existing one
- Finding thin pages that could be merged into a stronger one
Frequently asked questions
Is cannibalisation always a problem?
Not always. A guide and a product page can share a term because they serve different intents. It matters most when two pages are trying to answer the same question in the same way.
How do I fix it?
Merge the pages into the stronger one and redirect the old address, change one page to target a different keyword, or make the roles clear and link from the secondary page to the main one.
How are keywords compared?
Each keyword is reduced to its main words, with plurals merged and small joining words removed, then sorted. "Red shoes", "shoe red" and "the red shoes" all become the same key.
What format does the list need?
One page per line, with the address and the keyword separated by a comma, tab or bar. Either order works as long as one part looks like a web address.
Can I use it with several keywords per page?
Yes. Put the same address on several lines with a different keyword on each. Pages with six or more are listed as carrying many keywords.
