Source authority
The perceived credibility and influence of a source used in AI answers.
What is Source authority?
Source authority can reflect reputation, topical depth, links, original evidence, editorial standards, and consistency. It is not identical to a third-party SEO metric. The strongest practical signal is repeated use across relevant answers.

Why it matters for AI visibility
AI answers can shape awareness and buying decisions before a person visits a website. Understanding source authority helps teams connect what a model says with the prompts, sources, and technical signals that influenced the result. The useful next step is to observe the evidence, compare it over time, and act on the specific gap.
How to measure or use it
- Define the scope. Choose the relevant market, prompts, models, locations, and time window.
- Keep the evidence. Save the complete answer, its citations, and the page or claim being evaluated.
- Compare patterns. Look for repeated movement across prompts and models instead of reacting to one response.
- Take a specific action. Improve the owned page, correct a claim, earn third-party inclusion, or create better evidence.
