Prompt battery
A fixed set of realistic questions used to measure AI search visibility. The same questions are put to the major assistants on a schedule, and the share of answers naming a given agent is their mention rate. Keeping the set fixed is what makes the trend meaningful.
A useful battery is built from questions real home buyers and sellers ask, phrased the way people phrase them: "who is a good realtor for a first condo in Arlington," not keyword strings. It spans the agent’s actual neighborhoods and specialties, and it does not change between runs, because a moving measure measures nothing.
The battery is our core measurement instrument. It runs against ChatGPT, Perplexity, Gemini, and Google AI Overviews, and the resulting mention rate leads the monthly report.
