Keyword Clustering Tool

Group a keyword list into topic clusters by shared terms — to plan pages, avoid cannibalization and build topic hubs. Runs offline in your browser.

How to use

  1. 1Paste keywords, one per line (from any keyword tool).
  2. 2Adjust similarity, then copy the clusters — each cluster is a candidate page.

How it's calculated

Keywords are reduced to meaningful word stems (stop words removed). Two keywords join the same cluster when the share of stems they have in common (Jaccard similarity) meets the threshold.

Frequently asked questions

Why cluster keywords?

Keywords with the same intent should be targeted by one page. Clustering shows which terms belong together and which need their own page.

How does this differ from SERP-based clustering?

Commercial tools compare Google results for each keyword. This tool uses word overlap — fast, free and private, but less precise for synonyms.

What similarity should I use?

0.5 is a good start. Raise it for tighter clusters, lower it to group more broadly.
