What ContentGecko Keyword Clustering is
ContentGecko Keyword Clustering is a web tool that groups keywords by similarity across Google search results. For each keyword, it retrieves the top 10 results and forms clusters from URLs those results share. You can select a country and language for the SERP analysis and set a minimum overlap threshold; a higher threshold produces tighter clusters. You can also add your domain to see its organic rank in the report, then export clusters as CSV for other SEO or content planning tools. The free plan handles up to 200 keywords in one operation. Paid service costs €19.90 a month and supports up to 20,000 keywords per operation, with 50,000 keyword credits per month. Paid features include search intent, page type and funnel labels, clustering history, a premium algorithm, and dedicated clustering support. The tool focuses on SERP similarity rather than search volume, which requires a separate keyword research tool.
