The measurement

Questions come from the brand description — sector, services, competitors, markets — and are phrased the way a customer would ask them. “Which is the best dental clinic in Guimarães”, not “dental clinic Guimarães”. The difference matters: the first is what people actually type to an assistant.

A typical run is 45 measurements: fifteen questions across three engines. Each export market adds five more questions.

All three engines are queried with live search — the mode a real customer uses. Measuring without search would measure the model's memory, which is a different thing and goes stale with every update.

Every measurement keeps the exact text the engine returned, the sources it cited, the brand's position and the date. That is what turns the number into a verifiable claim: when a client asks “how do you know?”, you open it and show them.
