✅ Done — your keyword clusters
How it works
- Step 1 — Paste keywords, one per line (export them from any keyword tool).
- Step 2 — Tune the minimum cluster size and matching options.
- Step 3 — Each topic cluster lists its keywords with counts — copy any cluster or export them all.
Everyday uses
- SEOs — turn a 1,000-keyword export into a clean content calendar.
- Bloggers — find which keywords belong on one page vs. separate posts.
- Agencies — show clients a topic map instead of a raw keyword dump.
- Affiliates — group buyer-intent keywords into review roundups.
Rule: one cluster = one page. That is how you avoid keyword cannibalization.
