-³ DuckDuckGo has a crawler called DuckDuckBot. This crawler doesn't impact the linked results displayed; it just grabs favicons and scrapes data for a few instant answers. DuckDuckGo's help pages claim that the engine uses over 400 sources; my interpretation is that at least 398 sources don't impact organic results.

Compare DuckDuckGo side-by-side with Bing and Yandex and you'll see it's sourcing organic results from one of them (probably Bing). Update 2022: DuckDuckGo has the ability to downrank results on its own; it was previously working with Bing to get Bing to remove misinformation and spam:
