Google-GeminiNotebook: what it is and how to block or allow it

What Google-GeminiNotebook does

Google-GeminiNotebook fetches individual URLs that Gemini Notebook users add as sources to their projects, so the notebook can use the page's content. It doesn't crawl on its own. It is the renamed NotebookLM fetcher: Google renamed Google-NotebookLM in July 2026, when NotebookLM became Gemini Notebook.

• It visits only when a user adds one of your URLs as a source. Source
• Google said the old Google-NotebookLM name was supported until August 2026. Source

Does Google-GeminiNotebook follow robots.txt?

Generally not. Google lists it as a user-triggered fetcher, and these generally ignore robots.txt because a user requested the fetch.

It doesn't honor Crawl-delay.

How to stop Google-GeminiNotebook

robots.txt won't reliably stop it. A firewall or CDN rule that matches its user agent does, and also stops the feature for the people who asked for it.

Where to see Google-GeminiNotebook visits

Most bots never appear in Google Analytics. Many don't run JavaScript, so the analytics tag never loads, and Google Analytics 4 automatically excludes traffic from known bots and spiders. Your server or CDN logs record every request with its user agent, so search them for the bot's name.

OneLence AI visibility shows which pages AI crawlers read and fetch for answers, next to the visitors AI assistants send you and the ones that convert.

Other bots from Google

• Google-Extended: Not a crawler: the robots.txt setting for Gemini training and grounding. It doesn't affect Google Search.
• Googlebot: Googlebot is Google Search's crawler. Its crawl also decides whether your pages can appear in AI Overviews and AI Mode, so blocking it takes you out of both.
• Google-InspectionTool: Google-InspectionTool fetches your page when someone runs one of Google's Search testing tools, such as the Rich Results Test or URL Inspection in Search Console.
• Storebot-Google: Storebot-Google is Google's shopping crawler. It fetches pages for Google Shopping surfaces such as the Shopping tab in Search.
• GoogleOther: GoogleOther is a general-purpose Google crawler that product teams use for jobs outside Search, such as research crawls. Blocking it doesn't affect Google Search.
• Google-Agent: Google-Agent is the name AI agents running on Google's infrastructure use when they browse sites and take actions because a user asked them to.
• Google-Read-Aloud: Google-Read-Aloud fetches a page when someone asks Google to read it out loud. robots.txt doesn't stop it; a meta tag does.
• AdsBot-Google: AdsBot-Google checks the quality of Google Ads landing pages. It ignores the User-agent: * group, so it has to be named to be blocked, and blocking it can get your ads disapproved.
• Mediapartners-Google: Mediapartners-Google is the AdSense crawler. It reads pages that carry Google ad tags to pick relevant ads, and it ignores the User-agent: * group.
