Frequently Asked Questions
Should I Block Google-NotebookLM?
Probably not. Google-NotebookLM fetches a page when someone asks a question it can answer, and the response cites and links to your site. Blocking it removes you from those answers without improving your Google rankings, because assistants play no part in traditional search indexing. For comparison, 2% of the top websites we track already have robots.txt rules for Google-NotebookLM.
Does Google-NotebookLM Respect Robots.txt?
Yes. Google-NotebookLM is expected to honor robots.txt rules, so a disallow rule is the right first move. Automatic Robots.txt adds and maintains that rule for you, and Agent Analytics confirms Google-NotebookLM actually honors it.
Does Google-NotebookLM Access Private Content?
It has no way in. Google-NotebookLM fetches pages the way an anonymous visitor loads a URL, with no stored logins. Anything behind a paywall or a login stays out of its reach.
Why Is Google-NotebookLM Visiting My Website?
Someone asked Google's assistant a question your page can help answer. Google-NotebookLM retrieved the page in that moment to ground the answer, usually with a citation linking back to you.
How Can I Tell if Google-NotebookLM Is Visiting My Website?
Agent Analytics tracks Google-NotebookLM visits and every other known AI agent, crawler, and scraper alongside it, then authenticates each visit against Google-NotebookLM's published verification method. You can also check your server logs for requests whose user agent string contains "Google-NotebookLM". Look for fetches of individual pages that do not follow a crawl pattern. A log match is still not proof, because any bot can claim to be Google-NotebookLM.
