About the Keyword Clustering Tool
A long keyword list is hard to act on until it is grouped. This keyword clustering tool stems each phrase (so "shoe" and "shoes" match) and groups keywords that share meaningful words, names each cluster and suggests a primary keyword. If you paste volumes from your own source, such as Keyword Planner, they are used to pick the primary keyword and total the cluster.
Clusters help you plan one page per topic instead of one page per phrase, and they make a topic cluster structure (pillar pages linking to supporting articles) easier to design. Because grouping is based on word overlap rather than live search results, review the clusters and move keywords that share words but differ in intent. The tool runs in your browser, so your list stays on your device.
How to use it
- Paste keywords one per line, optionally with a volume after a comma or tab.
- Run the clustering and review the named groups.
- Merge or split clusters where intent differs and check each primary keyword.
- Export the clusters as CSV for your content plan.
Frequently asked questions
How does keyword clustering work in this tool?
It reduces words to their stems, ignores common stop words and groups keywords that share important stems. Each cluster is named after its most common terms. This lexical method is fast and private, but it does not compare live search results, so check groups manually where two phrases look similar but mean different things.
Can I include search volumes?
Yes. Add a number after each keyword, separated by a comma or tab, using volumes from Google Keyword Planner or another source you trust. The tool uses them to choose primary keywords and total each cluster. It does not supply or estimate volumes itself.
What is a topic cluster in SEO?
A topic cluster is a group of related pages: one broad pillar page covering the main topic and several supporting pages covering subtopics, all linked together. It helps visitors navigate and makes the relationship between your pages clearer to search engines.
