Prompt Tracking is the practice of running a fixed set of buyer-relevant prompts across AI engines (ChatGPT, Perplexity, Gemini, Copilot) on a schedule and recording whether, and how, your brand appears in the answers. It's the AI-search equivalent of rank tracking.
Why it matters
AI answers are non-deterministic: the same prompt can produce different brands on different runs, and answers shift as engines re-retrieve sources. One-off spot checks tell you almost nothing. Systematic prompt tracking turns AI visibility into a real metric, you see your citation rate trend, catch competitors displacing you, and measure whether a seeding campaign actually changed the answers. It's also how you find quick wins: prompts where you're mentioned on one engine but missing on another usually point to a source gap you can fix.
How to use it
- Build a prompt set that mirrors how buyers actually ask: "best [category] for [use case]", "[competitor] alternatives", "[your brand] vs [competitor]".
- Run each prompt multiple times per engine (outputs vary) and log mentions, position in the answer, and cited sources.
- Review monthly: falling citation rate on a prompt means re-checking which sources the engine now cites, then feed that into a source gap analysis.
