Topical authority is an SEO term for how fully and credibly a site covers a subject, shown by a connected set of accurate pages that answer the main questions and the follow-ups. It is not a Google metric or a score you can look up. It describes a goal, not a setting.
In short
The idea is simple: a site that explains a subject in depth, links its pages together and shows who wrote them serves readers better than one thin page on the topic. Imagine a Texas accounting firm with one page on small business taxes versus one with guides on deadlines, deductions, payroll and record keeping, all linked together.
List the questions a buyer asks in order, answer each on its own page, link related pages with descriptive anchor text, and keep the pages accurate and dated. Google recommends descriptive, concise link text and says every page you care about should have a link from another page on your site. Source: Google Search Central, links, read 9 November 2026.
