Definition Topical authority is measured across a content cluster, not a single page. Authority rises when core questions, subtopics, and related concepts under one topic get full coverage.
How it works The system evaluates the page count under a topic, internal linking density, external citation count, and user signals. Thematic consistency across topic clusters is assessed. Authority is observed through query capture patterns rather than a single metric: appearing across a broader keyword spectrum than competitors.
Where you see it in Scope Trends The **Content Hub** report lists every page under a target topic. The **Topic Gap** tab surfaces subtopics competitors cover that you do not. **Brief Producer** generates briefs for gap pages.
Frequently asked questions **How long does topical authority take to build?** 6-18 months depending on industry. Longer on new domains.
**How many pages are enough?** No fixed number. Aim above the competitor average for subtopic coverage.
