How many pages does it take to be seen as an authority on a topic?

No number. Google publishes no page count for topical standing, and figures quoted in SEO advice are invented. What builds standing on a subject is covering its real questions well, so that your pages rank for them and other sites cite them. A narrow subject may have a dozen questions worth answering; a broad one may have hundreds. The same count is complete in one case and thin in the other.
What actually builds standing
| Ingredient | What it looks like |
|---|---|
| Coverage | Pages answering the subject's main questions and the follow-ups people actually ask |
| Quality per page | Each page is a strong answer to its own search, not a filler entry |
| Connections | Pages link to each other where readers would want to move between them |
| Recognition | Other sites on the subject link to and cite your pages |
| Time | Rankings and citations accumulate as the pages prove useful |
Google has described a topic authority system for news, which looks at how much a publication covers specific subjects; for general search, it has not published a “topical authority” score. The practical lesson holds either way: depth and quality of coverage on a subject, and recognition from others, are what make a site the place people and search engines go for it.
Map the subject, not a target
- List the questions people ask about the subject, from the results pages, related questions, your own Search Console queries and customer questions.
- Group them by need; each group becomes one page, and sub-questions a reader would want answered together can share the page of the main question rather than getting their own.
- Mark which groups you already answer well.
- Build the missing ones, best first, and link them to the related pages.
Progress is measured in questions answered well, not pages published. A large set of thin pages that each say little adds up to less than a smaller set of complete ones, and a narrow subject can be covered with few pages.
Where to start
A new or small site gets further by covering one narrow subject completely before expanding, a choice argued in whether covering a topic broadly or deeply builds authority faster. Stop counting pages and start closing the gaps in the map.
