KeyClusters

What KeyClusters is

KeyClusters is a web service that groups keywords into topical clusters using real-time Google search results. For each keyword, it analyzes the top 10 ranking pages and groups terms when they share at least three pages. Users can upload CSV exports from Ahrefs or SEMrush, or use a custom file, then choose a geography and desktop or mobile results. Clustered results are available as a downloadable Excel file, with CSV export also offered. The maker says analysis usually finishes within minutes and queries are not throttled. One credit covers one keyword; users can add credits at any time, and purchased credits do not expire. The maker says there is no overall keyword limit if users purchase enough credits, while the listed keyword limit is 2,500. An API is available for teams integrating clustering into automated pipelines. KeyClusters is paid and has no free plan. One-time packs are $19, paid once for 2,500 keywords, $110, paid once for 20,000 keywords, or $350, paid once for 100,000 keywords.

Who it suits

KeyClusters is aimed at SEO professionals and agencies handling keyword lists at scale. It may also suit teams that want to automate clustering through an API.

Limits

The listed keyword limit is 2500 keywords. Analysis uses one credit per keyword, so processing more terms requires enough purchased credits.
