Prompt tracking is the practice of monitoring how AI engines answer specific, fixed prompts over time, so you can see how your brand’s presence, position, and sentiment change for the exact questions your buyers ask. It is the unit of measurement underneath AI visibility: every visibility metric is built from tracked prompts.
AI answers are non-deterministic and shift as models and sources update, so a one-off check tells you almost nothing. Tracking the same prompts repeatedly turns noise into signal, and lets you tie a change in your visibility to a specific page you shipped or a competitor move.
You choose a representative set of buyer-intent prompts, run them through each engine on a schedule, and record the structured result for each: presence, position, sentiment, competitors, and citations. Holding the prompts constant is what makes the trend meaningful.
Rankry is built on prompt tracking: a tailored prompt set per category, plus a Prompt Lab for your own.
