Keyword Clustering Tool
Paste a keyword list and group it into clusters of closely related keywords — each cluster is a page you can create or optimize, so you don't write several competing pages for the same search. Choose how strict the grouping is and export the result.
Paste up to 2,000 keywords, one per line. The tool reduces each keyword to its core words (ignoring stop words and merging plurals and verb forms), then groups keywords that share most of their core words with a cluster's head term. Loose grouping creates broad topics; strict grouping keeps only close variants together.

How to use Keyword Clustering Tool
- 1Paste your keyword list — from a keyword tool, Search Console or the Keyword Research Tool.
- 2Pick Loose, Balanced or Strict grouping.
- 3Review the clusters: each is named after its shortest, broadest keyword.
- 4Map each cluster to one page, and export the clusters to CSV.
Why cluster keywords
Many keywords are just different ways of asking the same thing — “seo checker”, “free seo checker” and “seo checker online” are all satisfied by one page. Writing a separate page for each splits your authority and can make your own pages compete (keyword cannibalization). Clustering shows you the real number of pages you need.
Target the head term of each cluster in the title and H1, and use the other keywords naturally in headings and copy.
How this clustering works — and its limits
This tool clusters by shared words (lexical similarity), which is fast, free and works well for close variants. It can't know when two differently worded keywords return the same Google results, or when similar-looking keywords have different intent (“apple pie recipe” vs “apple pie calories”). For those borderline cases, search both and compare the results, and check intent with the Search Intent Analyzer.
Frequently Asked Questions
Which strictness should I use?
Start with Balanced. Use Strict when you want separate pages for meaningfully different variants; use Loose for high-level topic planning.
What are unclustered keywords?
Keywords that didn't match any group. They may deserve their own page, or they're outliers. Try Loose to see if they fit a broader topic.
Is this SERP-based clustering?
No — it groups by shared words, not by comparing live search results, which keeps it instant and free. Verify important clusters by checking the live results.
Is the text I paste uploaded anywhere?
No. Pasted text is analyzed entirely in your browser and never leaves your device. Only the “From URL” option asks our server to fetch a public page.
