AEO Dictionary

Topical Authority

Topical Authority is the demonstrated, earned credibility of a website or content creator within a specific subject area, unlike domain authority which applies to the entire website. It is achieved by comprehensively and expertly covering a topic, consistently providing valuable insights, and earning references from other authoritative sources.

Why It Matters

AI models and search systems are adept at recognizing genuine expertise, looking for patterns that indicate deep knowledge. This makes topical authority a critical factor in AI Search Ranking and citation probability. Deep knowledge can only be presented if you have experience, so getting this experience out on the web is crucial. It's not just about being the 100th site to present a piece of information; it's about bringing grounded domain expertise.
