Should you block DuckAssistBot?

You can, but it may not listen. DuckDuckGo has not documented DuckAssistBot, so treat any rule as a request. Blocking it can prevent DuckAssist from using your content in AI-assisted search responses.

About robots.txtDuckDuckGo has not documented whether DuckAssistBot follows robots.txt, so a rule is a request, not a guarantee.

robots.txt
User-agent: DuckAssistBot
Disallow: /

Asks DuckAssistBot not to crawl any page. Add it to the robots.txt file at the root of your site, above any wider rules.

Ignored robots.txt?

Allowing DuckAssistBot only creates the possibility of retrieval. To find out whether your pages are selected, measure which answer engines actually cite your pages using a stable query set.

Spot it in your logs.

Match the name, then check where the request came from. Anyone can copy a user-agent.

    Match the name

    Search your server or CDN log for DuckAssistBot, case-insensitive. A match is a clue, not proof.

  2. 2

    Check the published IP ranges

    Compare the request’s source with the list DuckDuckGo publishes. Anything outside it is not DuckDuckGo. duckduckgo.com/duckassistbot.json

Is this really DuckAssistBot?
