What is an authority cluster in content strategy?

Last updated May 2, 2026

Quick Answer

An authority cluster is a group of interlinked content pieces organized around a central topic. It includes a comprehensive pillar page covering the main subject and multiple supporting articles addressing specific subtopics. The internal linking structure signals to search engines and AI that your site offers complete, authoritative coverage of that topic area.
