Frequently Asked Questions
What Traffic Patterns Should I Expect From GoogleAgent-Mariner?
GoogleAgent-Mariner operates a real browser, loading pages, running JavaScript, setting cookies, and navigating multi-step flows much like a person would. Because its route reflects the task it was given rather than a fixed crawl order, visits may look irregular. A session may pause while the agent processes a page, then continue somewhere unexpected.
Does GoogleAgent-Mariner Follow Robots.txt Rules?
No. GoogleAgent-Mariner is not expected to follow robots.txt rules, so a disallow rule only communicates your preference. Enforce the block with firewall or server rules, then use Agent Analytics to verify that its requests stop.
Is GoogleAgent-Mariner Used for AI Model Training?
Not ordinarily. GoogleAgent-Mariner is not categorized as an AI training scraper or data provider, so AI model training is not its expected purpose.
Does Blocking GoogleAgent-Mariner Affect AI Search or Citations?
Blocking GoogleAgent-Mariner can prevent people using the agent from accessing or acting on your website. It does not directly control whether your pages appear in an AI search index.
Does GoogleAgent-Mariner Access Private Content?
Possibly, if a user grants access. GoogleAgent-Mariner operates a real browser session, so when someone signs in through it, the agent can see anything available to that account. Without credentials, it can reach only what an anonymous visitor can.
How Can I Verify a Request From GoogleAgent-Mariner?
Agent Analytics tracks GoogleAgent-Mariner visits in real time. You can also check your server logs for requests whose user-agent string contains "GoogleAgent-Mariner". Look for browser-like sessions that move through pages faster or more methodically than a typical person. Because GoogleAgent-Mariner does not publish a verification method, any client can claim its identity and a log match is only a clue.
