Topical Authority (deeper)
Topical authority is the cumulative reputation a domain earns by comprehensively covering a topic — measured by depth, breadth, and quality of content in that topic area.
In context
Building topical authority is a multi-quarter project: identify your authority topic (the area where you are or want to be the canonical source), inventory the queries comprising that topic, plan and ship comprehensive content covering all major sub-topics. Authority compounds: the 50th article on a topic ranks easier than the 5th because the domain has earned topical recognition. Both Google's ranking systems and AI engines increasingly weight topical authority as a foundation for trust and citation.
Toronto SEO's topical authority on 'Canadian SEO' is built from 393 glossary terms + 71 comparisons + 20 vertical playbooks + dozens of pillar articles — a depth no competitor matches, reflected in citation rates and rankings.
