A measure of how completely and deeply a website covers a subject, used by search engines to judge trustworthiness and relevance. Rather than optimizing individual pages for individual keywords, topical authority means building a cluster of interlinked, comprehensive content around a central topic — so your site becomes a recognized authority for that topic as a whole. Both traditional search and AI systems reward topical authority because it signals expertise. See the full topical authority breakdown and learn how to build it with content clusters.
