Topical Authority
A site's demonstrated depth and credibility across a topic area, built through comprehensive content, entity coverage, internal links, and trust signals.
Topical authority is the degree to which a website appears knowledgeable and trustworthy across an entire subject area. Instead of ranking because one page mentions a keyword, a site with topical authority covers the topic deeply, answers related questions, uses relevant entities, and links related pages together.
Search engines infer topical authority from content depth, consistency, entity relationships, internal linking, backlinks, author expertise, and user engagement. A strong topic cluster usually includes a pillar page plus supporting pages that cover subtopics in detail.
To build topical authority, map the core entities and questions in a niche, publish comprehensive supporting content, link related pages contextually, cite authoritative sources, update old content, and maintain strong E-E-A-T signals.
