Keyword Cluster Builder
Paste a keyword list and get intent-grouped clusters with a suggested pillar-and-spokes structure and H2 ideas — a build-ready content map, not a spreadsheet you still have to interpret.
Paste keywords (one per line)
Paste at least 2 keywords on the left (one per line) to build the cluster map.
How to Turn a Keyword List Into a Content Map
Start from a raw keyword export — GSC, Ahrefs, a brainstorm — and leave with a build order.
Paste your keyword list
One keyword per line. Works with exports from Google Search Console, Ahrefs, SEMrush, or a plain brainstorm list.
Review the clusters
Keywords sharing a significant word are grouped together, tagged with an intent (informational, commercial, comparison), and ranked by size.
Build the pillar first
The largest cluster is your suggested pillar page — the broad hub. Every other cluster is a spoke that should link back to it.
Sanity-check ambiguous groupings
Word-overlap clustering occasionally over- or under-groups. Spot-check the SERP for any cluster that looks off before you commit to the structure.
How the Clustering Works
Four steps, entirely in your browser — no keyword volume or SERP data required.
Strip stopwords
Common connective words (the, for, near me, vs, how) are dropped before comparing keywords — only the significant terms count.
Group by shared terms
Keywords sharing at least one significant word are merged into the same cluster, transitively — a chain of overlapping keywords lands together.
Tag the intent
Each cluster is scanned for commercial (price, buy, hire), comparison (vs, alternative), commercial-investigation (best, top, review) or informational cues.
Rank pillar vs spoke
The biggest cluster becomes the suggested pillar; the rest are spokes, each with H2 phrasing suggestions pulled straight from the member keywords.
Why Cluster Before You Write
A content calendar built from an unsorted keyword list produces overlapping pages that compete with each other. Clustering first prevents that.

Keyword Cluster Builder FAQ
How is this different from SERP-based clustering tools?
Tools like SE Ranking or Ahrefs cluster by pulling the actual top-10 Google results for every keyword and grouping ones that share ranking URLs — the gold standard, but it needs a paid SERP data source. This tool clusters by shared significant words instead, entirely in your browser. It's a fast first pass, not a replacement for checking ambiguous groupings against the live SERP yourself.
Does the tool send my keyword list anywhere?
No. Clustering runs entirely in your browser with plain JavaScript. Your list never leaves your device.
What does "Pillar" vs "Spoke" mean?
The largest cluster is suggested as your pillar page (the broad hub topic); every other cluster is a spoke — a narrower page that should link back to the pillar. This is a starting suggestion, not a rule — check search volume and your existing site structure before committing.
Why did two unrelated keywords end up in the same cluster?
Clustering here is purely word-overlap based — two phrases sharing one common word (even a loosely related one) get linked, and clusters merge transitively. On a large list this occasionally produces an over-broad cluster. Split it manually if the grouping doesn't make sense for your content plan.
