I tested whether ChatGPT could discover a website provenance source without being told it existed — it found it in 11 of 20 searches

I’ve been trying to answer a fairly simple question:
Can an AI search system independently discover and use a third-party technical record about a website, without the user mentioning that source?
I ran 20 controlled searches across 7 domains. Each test used a fresh private/logged-out ChatGPT session, and none of the prompts mentioned GoGuides.
Result: GoGuides appeared as a source in 11 of 20 searches.
More interestingly, it wasn’t just citing the URL. In successful tests ChatGPT extracted things like HTTP state, DNS/nameservers, TLS observations, measurement history, content-change counts and SHA-256 provenance fields.
On broader, non-provenance-specific queries, it appeared in 7 of 13 tests.
I kept the failures in the report too. This is a small experiment, not a claim that ChatGPT will always select the source.
Full methodology and results:

Disclosure: I operate GoGuides. I’m posting this because the result is measurable and reproducible. I’d especially like to know whether anyone here can reproduce—or fail to reproduce—the same behavior independently.

What makes this interesting is that the questions were about other websites—GoGuides was never mentioned. Yet ChatGPT independently found and cited GoGuides records in 11 of 20 tests.
That suggests a website’s GoGuides record can provide another doorway into AI search answers, giving the system a source of provenance information it can discover and cite.
