Digital marketing term
Topic Cluster
A Topic Cluster is an SEO-focused content structure made up of a group of content pieces that cover different subtopics of a main pillar topic, all internally linked back to that pillar page.
Detailed explanation
In this structure, a central page covers the broad topic at a general level, while each supporting page dives deeply into a more specific question or subtopic, with all of them interlinked.
When search engines see this link network, they interpret it as evidence that the site has comprehensive expertise on the topic, which positively affects rankings for both the pillar page and its supporting pages.
This approach also strengthens user experience, since visitors can easily discover every aspect of the topic they're interested in within a single site.
