Frequently Asked Questions
What Traffic Patterns Should I Expect From Gemini-Deep-Research?
Gemini-Deep-Research makes isolated, on-demand requests rather than crawling your site. Traffic follows user demand, ranging from sporadic fetches to steady visits for a popular assistant.
Does Gemini-Deep-Research Follow Robots.txt Rules?
Gemini-Deep-Research is expected to follow robots.txt rules, so a disallow rule is the appropriate first step if you want to block it. Automatic Robots.txt can add and maintain that rule, while Agent Analytics lets you verify whether Gemini-Deep-Research respects it.
Is Gemini-Deep-Research Used for AI Model Training?
Not ordinarily. Gemini-Deep-Research is not categorized as an AI training scraper or data provider, so AI model training is not its expected purpose.
Does Blocking Gemini-Deep-Research Affect AI Search or Citations?
Yes, for requests handled by Gemini-Deep-Research. Blocking it can prevent the assistant from retrieving your pages for an answer or linking to them, but a separate crawler may control automatic AI search indexing.
Does Gemini-Deep-Research Access Private Content?
Not ordinarily. Gemini-Deep-Research fetches pages as an anonymous visitor without a stored login. Content protected by a paywall or login remains out of reach.
How Can I Verify a Request From Gemini-Deep-Research?
Agent Analytics tracks Gemini-Deep-Research visits in real time. You can also check your server logs for requests whose user-agent string contains "Gemini-Deep-Research". Look for a single-page request with no follow-up navigation. Because Gemini-Deep-Research does not publish a verification method, any client can claim its identity and a log match is only a clue.
