What it does

DuckDuckGo's web crawler for its search results.

DuckDuckBot is a web crawler for DuckDuckGo. DuckDuckBot’s job is to constantly improve our search results and offer users the best and most secure search experience possible.

DuckDuckGo

User agent

Requests from DuckDuckBot carry a user agent like this:

DuckDuckBot/1.0; (+http://duckduckgo.com/duckduckbot.html)

Device Detector identifies it with this pattern (a case-insensitive regular expression):

DuckDuck(?:Go-Favicons-)?Bot

Anyone can put any name in a user agent. Where the operator publishes IP ranges, checking the request's address against them is the way to confirm a visit is genuine.

How Vireo counts DuckDuckBot

Vireo keeps requests from DuckDuckBot out of your pageviews and visitors and counts them on its bot report under Search engines, so you can see how much it left out rather than wonder why your server logs show more traffic.

Checked by running Vireo Analytics' own bot filter over DuckDuckBot's user agents.
