Definition A content hub is the sum of a pillar page and its surrounding subtopic pages. All pages live under one URL folder or connect through an internal linking network. Users reach the whole topic from a single point.

How it works The pillar sits at the center of the hub. Cluster pages deeply explore specific subquestions. Sidebar or breadcrumb navigation gives access to all cluster pages from within the hub. Schema.org HasPart and isPartOf declare the hub structure to search engines. The internal link network among hub pages keeps authority flow inside the hub.

Where you see it in Scope Trends The **Site Structure** report detects your hub clusters and flags missing links. The **Content Studio** > **Build Hub** flow generates pillar and cluster briefs together.

Frequently asked questions **How many cluster pages does a hub need?** Minimum 5 clusters recommended. For authority, 15-30 clusters is the practical range.

**Should hub pages live under /blog?** A topic-focused folder (/glossary, /guide, /seo) shows the hub structure clearly and improves breadcrumb readability.
