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.
