The Content Cluster Builder turns a pillar topic and a list of subtopics into a hub-and-spoke internal-linking plan — the structure used by every top SEO blog.

What is the Content Cluster Builder?

A content cluster (also called a topic cluster) is a hub page covering a broad topic, surrounded by spoke pages covering subtopics in depth. Each spoke links up to the hub; the hub links down to each spoke. This structure tells Google you have topical authority on the subject.

How to use the Content Cluster Builder

Steps

  1. Enter your pillar topic.
  2. Enter at least 3 subtopics, one per line.
  3. Click Build. Use the diagram as your editorial roadmap.

  • Build topical authority.
  • Win for the head term and the long tail.
  • Plan editorial calendars cleanly.

Use cases

  • Building topic-driven funnels.

Pro tips

  • Pick a pillar broad enough to cover 6–10 spokes.
  • Each spoke should target a distinct intent.
  • Refresh the pillar whenever new spokes go live.
