About the Keyword Clustering Tool
The Keyword Clustering Tool groups a keyword list into topic clusters and turns them into a content plan, entirely in your browser. Keywords that share their distinctive words (not the seed every keyword contains) form a cluster, one page each; related clusters form a topic with a pillar page and supporting pages that link to it. Each page gets its search intent, a page type (guide, comparison, best-of list, tool page), the question keywords to answer as H2 sections, and the keywords to mention. Export the plan as a Markdown brief or CSV, and save projects when signed in.
Clustering runs in your browser, and a Search Console export you add is never uploaded. Only when you save a project (signed in) are its keywords stored with your account; delete the project, or your account, to remove them.
How to use the Keyword Clustering Tool
- Paste keywords, one per line, with an optional volume or impressions number after a tab or comma; or drop a Search Console export; or press "Cluster these" in the Keyword Generator.
- Choose the cluster size: Broad for fewer, bigger pages, Tight for narrower ones.
- Read each topic: the pillar page targets the broad phrase, supporting pages target their cluster keyword and link back to the pillar.
- Copy the brief or download the CSV, and save the project to come back to it.

Frequently asked questions
How does the clustering work without an API?
Each keyword becomes a TF-IDF vector of its words and word pairs, so words almost every keyword shares (usually the seed) count for little and the differences ("vscode", "chrome extension", "vs prettier") decide the groups. Keywords join the most similar cluster above the chosen strictness, most important first. SERP-based clustering, which compares Google results, is more precise but needs paid SERP data.
What is a pillar page?
A broad page on the main topic that covers it at a high level and links to a supporting page for each subtopic, which link back. The structure makes the topic easy to crawl and shows search engines the pages belong together.
Where are saved projects stored?
With your account on our server (keywords, weights and the cluster size), so you can open them on any device. Clustering itself runs in your browser; without saving, nothing leaves it. Deleting a project or your account removes them.
