A group of related articles built around a central pillar page, interlinked so search engines and readers can move between the overview and its supporting depth. Content clusters are the practical mechanism behind topical authority — instead of one page trying to rank for everything, a pillar covers a topic broadly while cluster articles cover each sub-question in depth, all linking back to the pillar. Well-built clusters distribute link equity, reduce keyword cannibalization, and make a site easier for AI systems to parse as a coherent knowledge base. See content clusters and topical authority.
