ContentGecko Keyword Clustering review
A focused SERP clustering tool with generous paid batch capacity and useful exports.
Reviewed by iTechGuides Editors · Editorial team · Updated Oct 2026
ContentGecko Keyword Clustering groups keywords according to similarity in Google search results. It fetches the top 10 results for each keyword, compares overlapping URLs, and forms clusters using a configurable SERP-overlap threshold. Users can choose a target country and language, import keyword lists from CSV, export clusters to CSV, and optionally check a domain’s organic rank. The tool is suited to SEO teams, content planners and agencies working on country-specific keyword sets, especially when SERP-based grouping matters more than a broader suite of SEO functions.
The free version provides a practical starting point: it clusters up to 200 keywords, uses the standard clustering algorithm, includes general website support chat, and supports CSV export. The paid plan costs €19.90 per month and includes 50,000 keyword credits per month, clustering for up to 20,000 keywords at once, a premium clustering algorithm, dedicated support, and account clustering history. Paid users also receive search intent, page type and marketing funnel labels, which add structure to the exported results and can help organize content planning workflows.
Its main strength is the combination of adjustable SERP analysis and large batch capacity. Country and language selection makes the clustering process more relevant for localized research, while the configurable minimum overlap threshold gives users control over how similar results must be before keywords are grouped. The free limit is better suited to smaller evaluations than large projects, and users who need labels or saved clustering history must choose the paid tier. Pick it for focused SERP clustering and CSV-based workflows; consider an alternative if you need a broader platform or native desktop and mobile applications.
