Free Keyword Cannibalization Identifier

How it works?

The Free Keyword Cannibalization Identifier helps you identify keywords that are closely related to your main keyword. A “similar keyword” might be a synonym, a plural form, or a slight rephrase of your main keyword. Remember, this tool is not for removing identical keywords. Instead, it finds and shows keywords that are similar but not exact.

  1. List your keywords one by one.
  2. Paste the list or upload the file in the input area.
  3. Adjust the Similarity threshold (higher values mean more similarity).
  4. Click the “Deduplicate” button.

Keyword cannibalization in SEO occurs when multiple pages on your site compete for similar search queries, like “guide for high-rated sci-fi movies” and “sci-fi movies high-rated guide.”

This internal competition confuses search engines, making it harder to assign a relevant page for the search terms and potentially lowering your site’s traffic.

What is keyword cannibalization?

Keyword cannibalization occurs when multiple pages on your website target the same search term, confusing search engines and splitting your traffic, potentially weakening each page’s visibility.

How do you identify keyword cannibalization?

Gather the primary keyword from each page of your website, often found in the page titles or H1 headers. Then, using a tool like ‘Similar Keywords Identifier’, input these keywords. By adjusting the similarity threshold in the tool, you can uncover keywords that are different but close enough to compete, indicating areas of potential cannibalization. This process helps pinpoint internal competition, where various pages may be unintentionally battling for similar keyword rankings.
