Keyword Clustering
What it is
Keyword Clustering is a web tool that groups keyword lists by semantic similarity and search intent to help plan pages for a website. It uses OpenAI’s GPT model to form clusters, with their number and size determined automatically. Each cluster can include a suggested page title and meta description. The service can add monthly search volume and cost-per-click figures from Keywords Everywhere, including total volume and average CPC for each cluster. Inputs include pasted keywords, CSV, TXT and Excel files, plus imports from Keywords Everywhere Favorites. Results can be exported as CSV or Excel, and read-only share 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 user’s Keywords Everywhere plan and ranges from 5,000 to 200,000 keywords. Logging in requires a Keywords Everywhere API key, and both free and paid plans from that service are supported. Generated clusters cannot be edited, though a new job can be started. Jobs are automatically deleted after one year.
