Expected Behavior
ExaUser 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.
How To Block ExaUser With Robots.txt
Add this rule to your robots.txt file to block ExaUser from accessing your website, or use Automatic Robots.txt to block all AI assistants at once. You can customize which pages are blocked by swapping out / for a different path.

Frequently Asked Questions
Should I Block ExaUser?
Usually not. Blocking ExaUser can keep your pages out of AI-generated answers and eliminate potential citation traffic. It does not improve traditional search rankings. Almost none of the top websites we track currently have robots.txt rules for ExaUser.
Does ExaUser Follow Robots.txt Rules?
Yes. ExaUser is expected to follow robots.txt rules, 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 ExaUser respects it.
Does ExaUser Access Private Content?
Not ordinarily. ExaUser fetches pages as an anonymous visitor without a stored login. Content protected by a paywall or login remains out of reach.
How Can I Tell if ExaUser Is Visiting My Website?
Agent Analytics tracks visits from ExaUser and every other known AI agent, crawler, and scraper, then authenticates each visit using ExaUser's published verification method. You can also check your server logs for requests whose user-agent string contains "ExaUser". 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 ExaUser.
Why Is ExaUser Visiting My Website?
A user asked Exa's assistant a question your page could help answer. ExaUser retrieved the page to support its response, often with a citation linking back to your site.
