Short answer
Filter your server or CDN logs by user agent for OAI-SearchBot, GPTBot, ChatGPT-User, OAI-AdsBot, Googlebot and Bingbot. Look at which URLs they request, response codes and frequency. ChatGPT-User visits are triggered by users asking about a page, which can hint at real interest.
What to look for
- 403 or 429 responses (blocked)
- Key pages never fetched (discovery issue)
- ChatGPT-User spikes on pricing or comparison pages
- Verify IPs against the published JSON lists
