What the Keyword Cluster Builder does
The Keyword Cluster Builder organises a flat keyword list into groups that share a head word, giving you a quick map of the themes hiding inside a long research list.
How it works
Each keyword is tokenised, stop words are dropped, and the first remaining word becomes the cluster key. Clusters are sorted by size so the dominant themes appear first.
- 1Paste your full keyword list.
- 2Set the minimum cluster size to hide one-off terms.
- 3Generate the clusters.
- 4Rename clusters mentally as content pillars.
- 5Save each cluster into its own collection.
Worked example
A mixed list containing three 'meal prep' phrases and two 'yoga' phrases produces a Meal cluster and a Yoga cluster.
Who uses it
- Turning a research dump into content pillars
- Deciding how many pages a topic needs
- Spotting themes you have over-covered
- Preparing structured input for Tag Boards
Best practices
- Clean and deduplicate the list before clustering.
- Raise the minimum size on very long lists.
- Treat clusters as drafts and merge similar ones by hand.
- One cluster usually maps to one pillar page.
Honest limitations
This is a lexical heuristic, not semantic clustering: synonyms with different head words land in different groups. Tagzy labels it clearly as a heuristic.
Frequently asked questions
- Is this semantic clustering?
- No. Grouping is by shared head word — a transparent, explainable rule.
- Why is one cluster huge?
- Many of your keywords start with the same meaningful word. Split it manually if needed.
- Can I export clusters separately?
- Yes, each group has its own copy button, or download the whole result.
