ContentGecko Keyword Clustering
Tallinn, Estonia
What it is
ContentGecko Keyword Clustering is a web tool that groups keywords by similarity among Google search results. It retrieves the top 10 results for each keyword and uses shared URLs to form clusters. Users can select a country and language for SERP analysis and set a minimum overlap level; higher thresholds make clusters tighter. Adding a domain lets users check its organic rank in the report, and clusters can be exported as CSV for other SEO and content planning tools. The free version processes up to 200 keywords at once and uses a standard algorithm. The tool focuses on similarity in search results rather than search volume, which requires a separate keyword research tool. The paid plan costs €19.90 a month and supports up to 20,000 keywords in one operation, with 50,000 keyword credits per month. Paid features include a premium algorithm, search intent, page type and funnel labels, clustering history, and dedicated support.
