Topic authority is the degree to which a site is treated as a credible source across an entire subject area rather than for a single query. It is built by covering a topic comprehensively and consistently, and it influences how readily individual pages on that topic rank.
Why Topic Authority matters for SEO
It explains why an established site can publish a thin page on its core topic and outrank a better page from a site with no history in the subject. It also explains why scattered content across unrelated topics underperforms concentrated coverage.
Pro tip on Topic Authority
Cover a topic in depth rather than publishing single pages across many subjects. Interlink related pages so the cluster is legible as a set. Keep the coverage current, since abandoned clusters decay. Resist expanding into topics you cannot cover credibly.
