Topical authority

Topical authority means a site covers a topic in such depth and breadth that search engines treat it as an expert source. It's built through interlinked articles that cover the subject from every angle.

Why it matters

Google increasingly rewards sites with demonstrable expertise (E-E-A-T). Topical authority helps you rank even for queries you don't directly target.

Real-world example

A marketing agency builds an interlinked glossary, playbooks and case studies. That signals deep expertise to Google — and lifts every page on the domain.
