Overview

ContentGecko Keyword Clustering is a web tool that groups keywords by similarity in Google search results. It retrieves the top 10 results for each keyword and builds clusters from URLs shared across those results. Analysis can be localized by country and language, and users can set a minimum SERP overlap; a higher threshold produces tighter clusters. A domain can be added to check its organic rank in the report, and clusters can be exported as CSV for other SEO and content planning tools. The free version handles up to 200 keywords in one operation. Paid service costs 19.90 EUR per month and supports up to 20,000 keywords per operation, with 50,000 keyword credits each month. Paid features add search intent, page type, and marketing funnel labels, plus clustering history and dedicated clustering support. The tool focuses on SERP similarity rather than search volume, which requires a separate keyword research tool. Its stated use cases include organizing keyword research, building content clusters, shaping SEO strategy, and avoiding keyword cannibalization.

Who it is for

It suits SEO and content teams that want to organize keyword research around search-result overlap and export clusters for planning. It is not a search-volume research tool.

What is good

  • Localizes SERP analysis by country and language.
  • Optional domain ranking appears in the report.
  • CSV export for SEO and content planning.
  • Paid plan handles up to 20,000 keywords per operation.

What to know first

  • Free version is limited to 200 keywords per operation.
  • Search volume requires a separate keyword research tool.
  • Paid service costs 19.90 EUR per month.

Verdict

ContentGecko focuses on search-result similarity, with localization, overlap controls, and CSV export. The free batch limit is 200 keywords; paid service expands capacity and adds cluster labels and history.
