Topic Cluster

A topic cluster is a content structure that connects a hub page of a central topic and sub-documents dealing with detailed topics through internal links. It is a representative way to build topic authority and implement semantic SEO.

A topic cluster consists of multiple documents that explain one topic. Hub pages provide the big picture of a topic, while cluster documents cover detailed concepts, questions, comparisons, and problem solving.

This structure helps users keep searching for relevant information and helps search engines understand that the site covers specific topics in an organized manner. The anchor text and context of internal links are also important.

A good topic cluster is not a bunch of duplicate articles. Each document should have its own search intent and role, and hubs and subdocuments should be interconnected.

Key takeaways

  • It consists of a hub page and a subcluster document.
  • Clarify topic relationships through internal links.
  • Used to create topic authority and semantic SEO.
  • Each document requires its own search intent and role.

Frequently asked questions

How can I distinguish between hub pages and cluster documents?

The hub page provides an overview of the entire topic and serves as a hub for links to sub-documents. The cluster document explains in depth a detailed concept not covered by the hub, and must link back to the hub page. If there are only clusters without hubs, or if the clusters are not connected to each other, the structure becomes weak.

How many cluster documents are appropriate?

It depends on the topic and coverage goals. It is realistic to start with 3-5 and expand while watching search performance and user response. Rather than increasing the number of clusters, it is more important to ensure that each document has a unique search intent and is naturally connected to the hub.
