What is Topical Authority?
Topical authority is Google's recognition that your site is a comprehensive expert resource on a specific subject. Built through deep, interconnected coverage of every subtopic in a field, it lifts rankings across the entire cluster - not just individual pages.
How Google measures topical authority
Coverage breadth (do you address every subtopic), depth (is each piece substantive), interconnection (do internal links create a topic graph), originality (do you offer unique insights), and external validation (do other authorities cite you).
Building topical authority
Map the topic completely (every subtopic, every related concept, every common question). Publish pillar + spoke clusters. Internally link them densely. Cite original sources and link out to authority. Earn citations from peers. Repeat for adjacent topics.
Topical authority vs. domain authority
Domain authority is the entire site's strength. Topical authority is per subject. A small site with deep dental SEO authority outranks Forbes on dental queries. Specialization beats general scale.
