Frequently Asked Questions
What does the EAS measure?
The composite health of your AI authority infrastructure — weighted across identity sovereignty, domain sovereignty, vocabulary sovereignty, and corroboration density — to produce a single score that maps to an LLM Ladder stage and drives remediation prioritization.
What score do most organizations receive on their first audit?
Between 35 and 55, placing them firmly in the Absent or Doubt range — even organizations with significant human-facing brand recognition and strong SEO performance often score in this range because AI authority infrastructure is distinct from web visibility infrastructure.
Can the EAS be gamed?
Short-term, tactical investments can temporarily lift the score without building durable authority. The Durability Classification framework distinguishes these from Architectural investments that produce lasting EAS improvement — the score is designed to be gamed-resistant through its weighting of temporal and structural factors.
