Running a prompt once against an AI platform gives an accurate, reliable AI-visibility measurement.
Direct Answer: LLM text generation is inherently non-deterministic. Running the exact same prompt twice in a row on ChatGPT or Perplexity can yield different phrasing, different source extractions, and different citations.
Actionable Takeaway:Build a prompt panel of 25 to 100 varied customer prompts reflecting different intent stages to track AI visibility accurately.
