Frequently Asked Questions
Should I Block Google-NotebookLM?
Usually not. Blocking Google-NotebookLM can keep your pages out of AI-generated answers and eliminate potential citation traffic. It does not improve traditional search rankings. For context, 2% of the top websites we track currently have robots.txt rules for Google-NotebookLM.
Does Google-NotebookLM Follow Robots.txt Rules?
Yes. Google-NotebookLM is expected to follow robots.txt directives, so a disallow rule is the appropriate first step. Automatic Robots.txt can add and maintain that rule, while Agent Analytics lets you verify whether Google-NotebookLM respects it.

How Can I Tell if Google-NotebookLM Is Visiting My Website?
Agent Analytics tracks visits from Google-NotebookLM and every other known AI agent, crawler, and scraper, then authenticates each visit using Google-NotebookLM's published verification method. You can also check your server logs for requests whose user-agent string contains "Google-NotebookLM". Look for a single-page request with no follow-up navigation. A matching log entry alone is not proof because any bot can claim to be Google-NotebookLM.
