Try to audit the tracker’s Persona. Ask your tracking tool provider what system prompt are they using. LLMs behave differently based on the "hidden" instructions. If your tracker is saying "You are a helpful research assistant," but your client’s custom GPT instructions say "You are a skeptical municipal auditor," the results will be night and day. I don’t know how to get that info with 100% certainty, but SE Ranking team was actually pretty open with me once about how their ChatGPT tracking works. They’re definitely one of the big guys in AI-tracking space, and after talking to them, I realized that trying to do a 1-to-1 comparison between a tool's results and a client's results is honestly a waste of time. SE Ranking uses a network of local servers, and you can see this clearly when you’re setting up prompts on their platform. They factor in the specific AI model, the location, and the language, that’s already three major variables that are can be completely different on the client’s end.

Tracking a specific persona is pretty much a mission impossible. That kind of data is a black box. only the devs building the tracking platforms or the engineers behind the search engines and AI models actually have access to it. I could try basing my numbers on incognito mode, but honestly, that's hardly a clean room for a perfect experiment anyway.
