Topical Authority
Topical authority is the depth and breadth of trusted coverage you have on a subject, which makes search and AI systems more likely to treat you as a go-to source for it.
Topical authority is being known for thoroughly covering a subject. Rather than a single strong page, it's the cumulative signal of comprehensive, high-quality, interlinked coverage across a topic — which teaches engines that your site is a reliable source on it and raises your odds of being cited across its questions.
It's built through topic clusters: a thorough set of pages addressing a subject's real sub-questions, linked together, reinforced by off-site corroboration. That depth is the authority pillar at the topic level, and it compounds — the more completely you own a subject, the more an engine defaults to you for its many related queries, including ones you haven't explicitly targeted.
Example. A site with twenty well-linked, genuinely useful pages covering every facet of "small-business bookkeeping" builds topical authority that a single bookkeeping article can't — so engines lean on it across the whole cluster of bookkeeping questions.
