# Content Authority

The perceived expertise and trustworthiness of your content by AI systems.

## What is Content Authority?

Content authority measures how AI search engines evaluate the quality, expertise, and trustworthiness of your content when deciding what to cite. High content authority comes from original research, expert authorship, comprehensive coverage, and being referenced by other authoritative sources.

## Why It Matters in 2026

AI systems are increasingly sophisticated at evaluating content quality. Thin, generic content is ignored while authoritative, expert content gets cited repeatedly.

## How to Improve

1. Publish original research with proprietary data  
2. Include expert author bios with credentials  
3. Cite authoritative sources in your own content  
4. Create comprehensive, long-form guides (2,000+ words)  
5. Update content regularly to maintain freshness
