Topical Authority FAQ: Questions People Actually Ask

**What is topical authority, in plain terms?**
Search engines increasingly evaluate sites at the topic level, not just the page level — a site with 40 shallow posts covering a subject often loses to a site with 15 posts that comprehensively covers every angle of the same topic.

**How often should this be checked?**
Regularly, not just once. Assuming more posts always means better coverage, when several thin, overlapping posts often signal less authority than fewer comprehensive ones. Set a recurring reminder rather than trusting memory.

**What's the most common mistake here?**
Publishing broadly across many unrelated topics instead of building depth in a smaller number where genuine expertise and authority can accumulate.

**Does this actually affect rankings, or is it just best practice?**
It's rarely a single ranking factor on its own, but it affects whether search engines and users can do what you actually need them to do — which shows up in rankings indirectly, often more than any one direct factor would.

**What's the fastest way to check this on an existing site?**
