Definition & Overview

Topical Authority is a measure of a website's depth, expertise, and comprehensive content coverage across an entire subject area or market niche.

Built by systematically publishing interconnected articles covering every subtopic, nuance, and user query within a specific domain rather than publishing isolated articles.
