Short answer: ask ChatGPT the questions your buyers ask, every day, and log three things: whether it names you, in what position, and which pages it cites. One answer is a sample. Thirty days of answers is a trend.
Why it matters now
Traditional search engine volume is expected to drop 25% by 2026 as people turn to AI chatbots. If ChatGPT skips you, the buyer never sees your site.

FAQ
Does ChatGPT give everyone the same answer?
No. Wording, location and memory change it. Track many runs.
How often should I check?
Run daily, read weekly. One bad day is noise. Four bad weeks is a signal.
Which engines should I track first?
Start with ChatGPT, then add Perplexity and Gemini once your question list is stable.
