  "method": "One brand, one prompt set of 60, one window of 10 July to 10 August 2026, one set of probe runs. We then computed the headline 'visibility percentage' ten different defensible ways, varying only the definition, the engine selection and the time window. No data was added or removed between calculations.",

  "finding": "The same brand over the same month reads anywhere from 0% to 40% depending on choices a client never sees. The single largest swing comes from the definition of 'visible': counting a prompt as covered if ANY run names you gives 40%, while requiring a majority of runs gives 0%.",
  "why_majority_is_zero": "No prompt in our set names us in more than half its runs. Our citations are real but sporadic, so any definition requiring dominance returns zero. That is a true statement about this brand and a useless one to report without the definition attached.",
  "engine_spread": "ChatGPT 23.3%, Google AI Overviews 21.7%, Perplexity 18.3%, Gemini 1.7%. Dropping the weakest engine moves the headline from 36.7% to 40.0%.",
  "limits": "One brand, one category, 60 prompts, 4 engines, 11-12 runs per series. The spread will differ by brand; the existence of a spread will not."
