Google AI Mode, AI Overviews and Gemini: what it does and what it costs
In short
Google's AI Overviews, AI Mode and the Gemini app draw on the normal Search index, so a site needs no extra file or markup to appear, and appearing costs nothing. Checkout through the Universal Commerce Protocol is on a waitlist, and merchants who adopt it stay merchant of record.

Cloudflare's scanner read gemini.google.com, which may serve a consent or redirect page, so the 0 may not describe the Gemini app itself.
What it does not do
- Google does not require llms.txt, AI text files or special schema markup for a page to appear in AI Overviews or AI Mode.
- Blocking Google-Extended does not remove a site from Google Search or its AI features; Googlebot rules and snippet controls do that.
