ExaUser is Exa's on-demand fetcher that retrieves live website content when a user or an application built on the Exa API requests it. You can set up Agent Analytics to see when ExaUser visits your website.

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.
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. For context, 7% of the top websites we track currently have robots.txt rules for ExaUser.
How Do I Block ExaUser Using 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
What Traffic Patterns Should I Expect From ExaUser?
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.
Does ExaUser Follow Robots.txt Rules?
ExaUser 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 ExaUser respects it.
Is ExaUser Used for AI Model Training?
Not ordinarily. ExaUser is not categorized as an AI training scraper or data provider, so AI model training is not its expected purpose.
Does Blocking ExaUser Affect AI Search or Citations?
Yes, for requests handled by ExaUser. 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 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 Verify a Request From ExaUser?
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.
How Is ExaUser Different From Other Exa Agents?
Exa operates separate agents for different purposes, so each agent should be evaluated and controlled independently.
- ExaBot: ExaBot is a web crawler that indexes web content to power Exa's AI search engine and semantic search APIs for AI applications.
- ExaSearchBot: ExaSearchBot is Exa's crawler for discovering and indexing public web pages so users can find, retrieve, and cite their content through Exa.
