Frequently Asked Questions

What Traffic Patterns Should I Expect From DuckAssistBot?

DuckAssistBot 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 DuckAssistBot Follow Robots.txt Rules?

DuckAssistBot 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 DuckAssistBot respects it.


Is DuckAssistBot Used for AI Model Training?

Not ordinarily. DuckAssistBot is not categorized as an AI training scraper or data provider, so AI model training is not its expected purpose.


Does Blocking DuckAssistBot Affect AI Search or Citations?

Yes, for requests handled by DuckAssistBot. 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 DuckAssistBot Access Private Content?

Not ordinarily. DuckAssistBot 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 DuckAssistBot?

Agent Analytics tracks visits from DuckAssistBot and every other known AI agent, crawler, and scraper, then authenticates each visit using DuckAssistBot's published verification method. You can also check your server logs for requests whose user-agent string contains "DuckAssistBot". 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 DuckAssistBot.


How Is DuckAssistBot Different From Other DuckDuckGo Agents?

DuckDuckGo operates separate agents for different purposes, so each agent should be evaluated and controlled independently.
