Frequently Asked Questions
What Traffic Patterns Should I Expect From bigsur.ai?
bigsur.ai 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 bigsur.ai Follow Robots.txt Rules?
bigsur.ai 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 bigsur.ai respects it.
Is bigsur.ai Used for AI Model Training?
Not ordinarily. bigsur.ai is not categorized as an AI training scraper or data provider, so AI model training is not its expected purpose.
Does Blocking bigsur.ai Affect AI Search or Citations?
Yes, for requests handled by bigsur.ai. 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 bigsur.ai Access Private Content?
Not ordinarily. bigsur.ai 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 bigsur.ai?
Agent Analytics tracks bigsur.ai visits in real time. You can also check your server logs for requests whose user-agent string contains "bigsur.ai". Look for a single-page request with no follow-up navigation. Because bigsur.ai does not publish a verification method, any client can claim its identity and a log match is only a clue.
