# What is Topical Authority? Topical Authority, explained

> Be the deepest source on a topic.

Topical authority is the depth and breadth of a site's coverage of a single subject. Search and answer engines reward sites that cover a topic comprehensively — pillar pages, supporting clusters, internal linking — over sites that publish one article and move on. Topical authority is the long-term game underneath every AI-search optimization tactic.

## How Topical Authority differs from SEO, Entity SEO, E-E-A-T

Domain Authority / Domain Rating is a third-party score (Moz, Ahrefs) summarizing backlink profile. Topical authority is about coverage depth on a specific subject — and it's what AI engines weigh when deciding whose source to cite.
