What Keyword Clustering is
Keyword Clustering is a free web tool that groups keywords by semantic similarity and search intent, helping teams organize terms for website pages. It uses OpenAI’s GPT model to form clusters, with their number and size determined automatically, and suggests a page title and meta description for each cluster. The tool can add monthly search volume and cost-per-click data from Keywords Everywhere, including total volume and average CPC for each group. You can paste terms, upload CSV, TXT, or Excel files, or import from Keywords Everywhere Favorites. Results can be exported as CSV or Excel, and read-only sharing links can expire after 24 hours, 7 days, or 30 days. The free plan allows up to 10,000 keywords per job; the daily limit depends on the Keywords Everywhere plan and ranges from 5,000 to 200,000 keywords. Signing in requires a Keywords Everywhere API key, and either its free or paid plan is supported. Generated clusters cannot be edited, though you can start another job. Jobs are kept for one year before automatic deletion. The maker describes the tool as intended for agencies, freelancers, and in-house teams doing keyword mapping and content planning.
