The Publication Intelligence Index tracks which publications AI engines are actually citing.

This matters because not all media coverage carries the same machine value. Some publications appear again and again inside AI-generated answers. Others may still be credible to humans but less visible to retrieval systems.

Core answer

The Publication Intelligence Index is AuthorityTech's live resource for understanding which editorial sources appear most often in AI-generated answers. It helps founders, CMOs and PR teams prioritize coverage based on machine citation behavior, not just legacy prestige.

Why this matters

Traditional PR ranks outlets by brand recognition, audience and reputation. Those still matter. But AI search adds another layer: whether the publication is retrieved and cited by AI engines when buyers ask category-level questions.

A placement in a trusted publication can become a durable AI visibility asset if the machine retrieves it. A placement in a publication that machines rarely cite may have less compounding value.

Use cases

• Identify which publications matter most for AI visibility.
• Prioritize earned media campaigns around machine-cited sources.
• Compare legacy prestige against actual AI citation behavior.
• Build PR briefs around publications already trusted by AI engines.
• Measure whether new coverage is appearing in the answer layer.

How to use it

1. Open the Publication Intelligence Index.
2. Look for publications that appear across relevant category queries.
3. Compare those publications against your current PR targets.
4. Build pitches that create extractable claims inside those trusted sources.
