Prompt tracking is monitoring a fixed set of buying questions across AI models on a schedule, recording every answer, and measuring how a brand's presence in those answers changes over time.
The prompt set is the instrument panel. A CRM vendor might track "best CRM for startups", "Salesforce alternatives", and "top CRMs for small business" — each prompt asked to each model, weekly, with the answers recorded and scored.
Consistency is what makes tracking meaningful: the same prompts, the same models, the same schedule. Change the questions every week and the trend line measures your curiosity, not your visibility.
