Example shown — replace it with your own keyword list.
How the keyword grouper works
- Paste your keyword list, one per line.
- The tool strips common filler words (like "the," "for," "best") and looks for whichever meaningful word appears most often across your list.
- Keywords are grouped around their most frequently shared significant word, with anything left over grouped as "Other."
FAQ
How does the grouping actually work?
It looks for the significant (non-filler) word each keyword shares most often with the rest of your list, and groups keywords around that shared word — a simple co-occurrence heuristic, not true semantic clustering, so it works best when your keywords genuinely share obvious topic words.
Why do some keywords end up in "Other"?
A keyword lands in "Other" when none of its significant words appear in at least one other keyword — meaning it doesn't share an obvious topic word with anything else in your list.
Is this the same as real semantic keyword clustering?
No — proper semantic clustering (as used by dedicated SEO tools) considers search intent and meaning, not just shared words, so it can group "cheap sneakers" and "affordable trainers" together even without an overlapping word. This tool is a simpler, purely word-based starting point.
Is my keyword list sent anywhere?
No. Grouping happens entirely in your browser as you type — nothing is sent to Online Tool Store or stored.
