Free keyword cluster tool
Paste a keyword list and group it into clusters you can map to pages, then export to CSV.
What is keyword clustering?
Keyword clustering groups search terms that share the same meaning and intent so you can target them with one page instead of many thin ones. It prevents keyword cannibalization and gives each page a clear job.
How this keyword cluster tool works
- Paste up to a few hundred keywords, one per line.
- The tool removes filler words, normalizes plurals and groups keywords that share important terms.
- Choose broad clusters for topic planning or tighter clusters for page mapping.
- Download the result as CSV and assign each cluster to a URL.
This tool groups by shared words, which is fast and transparent. For final page mapping, check the top results for the head term in each cluster: if the same pages rank for two clusters, they probably belong on one page. Read our keyword research guide for the full process, then build authority to each page with link building packages.
Keyword Cluster Tool FAQ
Where does a keyword go when it fits two clusters?
A keyword that fits two clusters goes to the page that looks most like the current top results. Search it and compare. Assign it there and leave it out of the other cluster. Split results usually mean the keyword is secondary for both pages, so mention it naturally in each instead of building a third page.
What does the shared word setting change?
The shared word setting controls how tight each cluster is. One shared word groups keywords into broad topics, which suits planning a site section. Two shared words split those topics into page sized groups, which suits mapping keywords to individual URLs. Run both passes on the same list and compare the results.
How many keywords can I cluster?
The tool runs in your browser and handles a few hundred keywords comfortably. For very large lists, split them by topic first and cluster each group separately.
Does it use search results to cluster?
No. It clusters by shared meaningful words, which is quick and free. Validate important clusters by checking whether the same pages rank for each keyword in Google.
What should I do with each cluster?
Assign each cluster to one page. Use the shortest, highest volume keyword as the primary target and cover the rest naturally within the content.
Is the keyword cluster tool free?
Yes. It is free with no signup, and your keyword list never leaves your browser.

How does a keyword cluster tool turn a raw list into a page plan?
A keyword cluster tool turns a raw list into a page plan in 6 steps, ending with one URL assigned to each cluster.
- Collect: export keywords from your research tool, Google Search Console and competitor pages into one list.
- Clean: remove irrelevant terms, unwanted brand names and obvious duplicates.
- Cluster broadly: run the keyword cluster tool with one shared word to see the main topics.
- Cluster tightly: rerun with two shared words to split each topic into page sized groups.
- Check intent: search the main keyword in each cluster and look at what ranks.
- Map: assign each cluster to an existing URL or a new page, and note the gaps.
Which page type fits each keyword cluster?
Search intent decides the page type, and 5 groups of signal words point to 5 page types.
| Cluster signals | Page type |
|---|---|
| how to, guide, tips, ideas | Blog post or guide |
| best, top, vs, alternatives | Comparison or list article |
| service, company, near me, a city name | Service or location page |
| buy, price, cost, cheap | Product, category or pricing page |
| what is, meaning, definition | Glossary or explainer article |
How do you keep a cluster plan free of cannibalization?
Keep a cluster plan clean with 2 rules: one cluster per URL, and improve a ranking page before creating a new one. Two pages that target one cluster compete for the same searches. A page that already ranks for part of a cluster has history and links, so improving it beats starting over.
Keep the exported CSV as your master map. Add columns for the assigned URL and each page's status, so the plan stays useful after the first round of content.
Our keyword research guide covers how to build the list in the first place. Once clusters are mapped, our SEO content writing team produces the pages. A link building plan then decides which pages get links first.
