Topical Authority

Topical authority is the state of a site being treated as a dependable source on a subject because it covers that subject thoroughly and consistently, rather than because of any single page or link. It is a property of a body of work.

Coverage, not volume

The reliable way to build it is to answer the questions a subject actually raises, including the small and awkward ones that no keyword tool surfaces because almost nobody searches them. A site that covers the obvious questions and stops looks, from the outside, like every other site that stopped there.

The failure mode is treating the count of pages as the goal. Publishing forty thin pages on a subject demonstrates that forty pages were published. It also creates pages competing with each other for the same queries and gives a reader no reason to trust any of them, which is the opposite of the intended effect.

Why it matters more where answers are composed

A ranked list can include one good page from a site that knows nothing else about the subject. A system composing an answer is doing something closer to choosing whom to believe, and repeated encounters with a source across a subject are part of what makes it a plausible one to name.

This is the argument for building a subject out properly, a small number of pages that each answer one thing completely, linked so that the relationship between them is explicit, rather than for producing more pages. Topic clusters and pillar content are the usual structures for expressing it.

One question people ask

Is this the same as domain authority?

No, and conflating them leads people the wrong way. Domain authority is a third-party score estimating a whole site’s link strength, and it is subject-blind: a strong site is scored strong on subjects it has never written about. Topical authority is specific to a subject and can belong to a small site that covers one thing properly. The small specialist site outranking the large generalist on a narrow question is the ordinary case, not the exception.
