Topic Cluster

A topic cluster is a content strategy model where a 'pillar page' covers a broad topic comprehensively, and multiple 'cluster pages' dive into specific subtopics, all interlinked. For example, a pillar page on 'SEO' links to cluster pages like 'Technical SEO', 'On-Page SEO', and 'Link Building'. This structure signals topical authority to search engines and improves crawl efficiency. Internal links pass link equity and help users navigate deeper into your content. Over time, strong topic clusters can dominate SERPs for a wide range of related queries.
