Prompt Audit

The process of running a defined prompt library across major AI engines, capturing the responses, and analyzing them for brand presence, accuracy, sentiment, and source citations. The atomic unit of AI visibility measurement.

Why it matters

Prompt audits convert AI visibility from abstract claim into measurable data. Each audit reveals which engines surface the brand, which sources drive descriptions, and which competitors win the buyer's attention — improving competitive benchmarking and supporting commercial discoverability decisions.

Implementation

At the implementation layer, prompt audits run quarterly or monthly across the prompt library, with results categorized by engine, prompt type, and competitor. Audits combine automated capture with human review for accuracy and sentiment. 5W operates prompt audits as a quarterly tracking program for clients.

Common failure modes

  • Single-pass audits without statistical reliability
  • No human review of automated results
  • Sentiment scoring without category-aware calibration
  • Engines tested in inconsistent ways across audit cycles
