What it checks
What the Keyword Clusterer looks at
Group by similarity
Within each group, phrases are merged when they share at least the percentage of words you set. 90 percent is strict; 50 percent is loose.
Minus and plus words
Drop phrases containing minus words; keep only phrases containing at least one plus word.
Volume column
Add a volume after each keyword, separated by a tab, comma or space, and the clusters show totals.
How to read it
From clusters to pages
From clusters to pages
Each cluster is usually one page: the phrases in it are the page’s target, its H2s and its FAQ. A cluster with high total volume and clear commercial intent is a service page; a cluster of questions is a guide. Clusters with one phrase each either need a looser similarity setting or are genuinely one-off searches.

FAQ
Questions about this tool
Anything else? (970) 399-9004 reaches a person in Fort Collins, not a call center.
How is the shared word chosen?
Each phrase is split into words; the word that appears in the most phrases becomes the group name, and phrases are assigned to the most frequent word they contain.
What does the similarity percentage mean?
The share of words two phrases have in common. At 90 percent only near-duplicates merge; at 50 percent “buy red shoes” and “red shoes online” merge.
Can I cluster in languages other than English?
Yes. The grouping is based on the words you paste, in any language.
Is the list uploaded?
No. Clustering runs in your browser and the CSV is generated there too.
