This is actually a fundamental limitation of prompt-monitoring approaches — personalization, location variance, account history all introduce noise that's hard to control.

One alternative is page-level structural analysis: instead of asking ChatGPT "do you cite this site?", you analyze the page directly for the signals that predict citation — source density, answer structure, fluency, statistics. No account needed, no IP variance, fully reproducible.

That's the approach I took with writeseo.vercel.app/geo-check — based on the Princeton KDD research (same paper vincko linked above). Different layer of the problem, but more stable as a diagnostic.
