The part about which pages the answer was built on is what I'd actually pay attention to. When we first ran a couple dozen buyer-style prompts through Gemini by hand we weren't named once, and a bare zero told us nothing about what to fix. Seeing whose pages the engine pulled from instead would have. When your brand isn't mentioned at all, do you still show the source pages for that prompt, and can you see which domains come up across many prompts rather than one answer at a time?
