Topical Authority Topical Authority Be the deepest source on a topic.

Topical authority is the depth and breadth of a site's coverage of a single subject. Search and answer engines reward sites that cover a topic comprehensively — pillar pages, supporting clusters, internal linking — over sites that publish one article and move on. Topical authority is the long-term game underneath every AI-search optimization tactic.
