How to use it

How to use the keyword clustering tool.

  1. Paste your keywords, one per line. Add a comma and the search volume if you have it.
  2. Add words to ignore, such as your city or "best", so they do not drive the grouping.
  3. Choose how strict the grouping should be and click Cluster keywords.
  4. Use each cluster as one page: the top keyword becomes the target, the rest become supporting terms.

Why cluster keywords before writing content?

Search engines rank pages for groups of related queries, not single keywords. If you write a separate page for every variation, your pages compete with each other, which is called keyword cannibalisation. Clustering groups similar searches so one strong page can rank for all of them.

This tool groups keywords by the meaningful words they share, after removing common filler words and plurals. It works entirely in your browser. For the most accurate clusters, SEO teams also compare live search results: if two keywords show mostly the same top pages, they belong on the same page.
