Definition
Topical authority is the depth and breadth of expertise a site shows on a subject, judged by the quantity, quality, and interconnection of its content. Strong topical authority makes a site far likelier to be cited as a primary source.

How Topical Authority Works
Covering one slice of a topic well is fine. Covering the whole thing, with interlinked pages that connect the pieces, tells engines your site genuinely owns the subject, not just a corner of it. The interlinking does real work here. It shows the engine how your coverage fits together.
Why Topical Authority Matters
Engines prefer to cite sources that clearly own a subject. Building a connected cluster of strong content, rather than scattered one-offs, is one of the most durable ways to become the source they keep coming back to. A well-linked glossary is a good example of exactly this.
