Topical Authority Cluster Builder

What Topical Authority Cluster Builder does

This tool takes a raw, unsorted list of keywords and groups them into clusters based on shared core terms, organized as a hub-and-spoke model: a main "hub" topic with related "spoke" keywords underneath it. It's a quick way to turn a messy keyword export into the shape of a content structure, where one pillar page can link out to several supporting pages.

How to build keyword clusters

Paste your keyword list, one phrase per line.
Select Build clusters.
Review the groups — each cluster shows a hub term with its related spoke keywords listed underneath.

How the grouping works

Keywords are grouped by the meaningful words they share once common stop words and filler terms are stripped out. Phrases with overlapping core words — like "marathon training plan" and "marathon training for beginners" — land in the same cluster, while unrelated phrases form their own groups. It's a pattern match on shared vocabulary, not an understanding of search intent, so it's worth a quick manual review before building a content plan from the output.

Turning clusters into content

Hub term → a broad pillar page covering the topic comprehensively.
Spoke keywords → supporting pages or sections that go deeper on one angle, each linking back to the hub.
Isolated single-keyword clusters → often signal a keyword too narrow for its own page, better folded into a related cluster.

Často kladené otázky

How many keywords can I paste in at once?

There's no hard limit built into the tool — it comfortably handles anywhere from a handful of keywords to a few hundred pasted lines.

Does the clustering understand search intent, or just shared words?

Just shared core words after filtering out common stop terms. Two phrases with similar wording but different intent can end up in the same cluster, so review the groups before acting on them.

What should I do with a cluster that only has one keyword?

A lone keyword with no spokes often means it's either too narrow to be its own page, or simply didn't share enough vocabulary with anything else in your list — check it against the other clusters manually.

Can I paste keywords with search volume data attached?

Paste one keyword phrase per line — strip out any extra columns like volume or difficulty first, since the tool reads each line as a single keyword.

Does this tell me which hub to prioritize first?

No — it groups and structures your list; deciding which cluster is worth building first is a judgment call based on your own traffic and business priorities.
