Topical authority
Being the site that covers a subject so thoroughly that search engines and AI trust it on that subject.
In plain English
One great page rarely wins alone. A site that answers the main questions, the follow-ups and the edge cases on a topic, and links them together, becomes the obvious source for that topic.
In practice
A foundation repair company with clear pages on cracks, settling, costs, warning signs and repair methods outranks a general contractor with one page.
