Topic Cluster Generator — Group Keywords by Cluster
Topic Cluster Generator
A topic cluster generator groups a flat keyword list into related clusters by shared terms and phrasing, then labels each cluster with a name and identifies the broadest, highest-volume keyword in it as the likely pillar page, with the remaining narrower keywords proposed as supporting pages that link back to it. This turns an unstructured list into a site structure that concentrates topical authority instead of spreading it across disconnected pages.
Paste a keyword list and get it grouped into topic clusters with a suggested pillar page and supporting articles for each group. Free, no signup.
