Keyword Clustering review
A free semantic clustering tool with useful exports, visual maps, and Keywords Everywhere data.
Reviewed by iTechGuides Editors · Editorial team · Updated Oct 2026
Keyword Clustering is a web-based tool for SEO professionals, freelancers, agencies, and in-house content teams. It groups keyword lists by semantic similarity and search intent, then adds search volume and CPC metrics through Keywords Everywhere. Users can paste keywords or upload CSV, TXT, and Excel files, while Keywords Everywhere Favorites import provides another way to bring in existing lists. The tool is suited to teams that need structured keyword groups and content-page direction without a paid product tier.
Its strongest fit is the combination of semantic grouping and practical output. Automatic cluster naming and page suggestions help turn grouped keywords into an initial content structure, while sorting, filtering, and keyword search make larger result sets easier to review. The interactive cluster map adds a visual way to inspect relationships between groups. Results can be exported to CSV or Excel, shared through expiring read-only links, and revisited through one-year clustering job history.
The main consideration is its dependency on the surrounding Keywords Everywhere setup. Access requires a Keywords Everywhere API key, and daily usage limits depend on the user's Keywords Everywhere plan. OpenAI is also listed as an integration, but the core workflow remains focused on semantic clustering rather than a broader SEO research suite. There is no SERP analysis, so users who need search-result examination should choose a tool built around that capability instead. Keyword Clustering is a sensible pick for free semantic organization, visual review, and spreadsheet-ready exports; it is less suitable for teams seeking an all-in-one platform or independent access without Keywords Everywhere.
