Topical Authority is the perceived depth, breadth, and credibility of a website’s coverage around a subject area.
It matters because organic search compounds over time when pages are technically accessible, useful, differentiated, and connected to real search intent. Clear SEO terminology also helps teams avoid shortcuts that create long-term risk.
Example
A specialist site can cover selection, installation and troubleshooting questions with clear, connected resources. Evaluate the usefulness and evidence of that coverage rather than assuming publishing a fixed number of articles creates a measurable authority score.
