Topical Authority
Topical authority is a website's demonstrated expertise depth in a specific subject area, directly influencing how often AI systems like ChatGPT and Perplexity cite it as a source.
Full Definition
Topical Authority refers to a website's recognized expertise and comprehensive coverage of a specific subject area. AI systems and search engines use topical authority signals to determine which sources are most reliable for particular topics.
How Topical Authority Works:
AI systems evaluate authority through:
- Coverage Depth: How thoroughly you cover a topic
- Content Interconnection: How well content links together
- Expertise Signals: Author credentials, citations
- External Recognition: Backlinks, mentions, citations
- Consistency: Focused expertise over time

1. Content Clustering

Why Topical Authority Matters for AI:
- AI prefers sources with demonstrated expertise

Authority vs. Size:
