What is a topic cluster?

A topic cluster is a content strategy that organizes related pages around a central hub page to establish authority and improve search rankings. The hub page provides an overview of a broad topic and links to multiple cluster pages (also called spokes) that cover specific subtopics in depth. Each cluster page links back to the hub and to other related cluster pages, creating an interconnected web of content.

A topic cluster structure includes:

• A central hub page providing a comprehensive overview of the broad topic
• Multiple cluster pages covering specific subtopics in depth
• Strategic internal linking where cluster pages link back to the hub and cross-link to related pages
• Comprehensive coverage of all aspects and questions related to the topic

This interlinking structure signals to search engines and AI models that your site offers comprehensive, authoritative coverage of the topic, making it easier for both searchers and search engines to discover related content while building topical authority.
