Topical Authority
01 Definition
Topical Authority meaning: The depth and breadth of a site's content on a subject, signaling subject-matter expertise.
Topical authority refers to how thoroughly a website covers a subject area through related, high-quality content. Many SEOs believe broad, well-connected coverage of a topic helps search engines see a site as a trusted source. It is a strategic concept, not an official metric that any search engine publishes.

Why it matters
How Topical Authority fits the work
Building topical authority encourages complete, connected coverage of a subject, which can strengthen a site's relevance and give users fuller answers in one place.
In context

Practical note
No search engine reports a 'topical authority' score, so treat it as a strategy, not a dial. Depth alone does not rank pages; quality, intent match, and links still matter.
