Questions
- What is Google-GeminiNotebook?
- Fetches the URLs that Gemini Notebook users add as sources to their projects. MetricRaven groups it under AI answers: assistants opening a page because a person asked about it.
- How do I verify that a request really comes from Google-GeminiNotebook?
- Check both the user agent and the IP. Requests from Google-GeminiNotebook contain "Google-GeminiNotebook" in the user agent and come from the IP ranges Google publishes (https://developers.google.com/static/crawling/ipranges/user-triggered-fetchers.json, https://developers.google.com/static/crawling/ipranges/user-triggered-fetchers-google.json). A request with the name but another IP is likely spoofed.
- How do I block or allow Google-GeminiNotebook?
- Add a robots.txt group for "Google-GeminiNotebook" with the paths to allow or disallow. Fetchers that act for a user may ignore robots.txt; block those at your server or firewall instead.
- How can I see when Google-GeminiNotebook visits my website?
- Most crawlers never run JavaScript, so browser analytics miss them. MetricRaven's @metricraven/ai-crawl package reports crawler requests from your server, verifies their IPs against published ranges, and shows which pages each crawler reads.
