A strategic grouping of content designed to establish expertise and authority on a specific topic.
An authority cluster is an advanced content strategy combining topic clusters with E-E-A-T signals. It includes pillar content, supporting articles across funnel stages (TOFU/MOFU/BOFU), author expertise pages, and strategic internal linking. The goal is to comprehensively cover a topic while demonstrating experience, expertise, authoritativeness, and trustworthiness to both users and search engines.
