What is topical authority?
Also known as: topic authority, topical relevance
Topical authority: Topical authority is the idea that a site which covers a subject thoroughly, accurately and consistently becomes a more trusted source on that subject than a site with a single page about it. It is a useful concept rather than a single metric that search engines publish.
Why does it matter?
Coverage breadth helps both people and systems understand what your site is about. A site with connected, well-linked pages answering the main questions in a topic is generally better placed to be chosen for related queries.
For AI search, depth gives you more ways in. When a question is broken into sub-queries, a site that answers many of the related questions well has more pages that could be retrieved.
How do you act on it?
- Pick the topics your business genuinely has expertise in rather than chasing unrelated traffic.
- Map the main questions and sub-questions in each topic and identify which you already answer.
- Build out the missing pieces and link related pages together with descriptive anchor text.
- Keep the cluster accurate over time; outdated pages undermine the rest.

Frequently asked questions
Is topical authority a Google ranking factor?
Google doesn't publish a "topical authority" score as a single factor. It is a helpful way of describing why sites with thorough, trustworthy coverage of a subject tend to perform well. Treat it as a strategy, not a metric to game.
How many articles do I need for topical authority?
There's no fixed number. Aim to answer the important questions in the topic well and link them coherently. Ten excellent, connected pages are generally more useful than fifty thin ones.
