The ''Zero-click Info'' section, following a search term request, clicks on the top links for users, and then pulls out snippet information from the site that apply to the specific search. It's intended to provide users the ability to learn about a search topic without having to click the link.<ref name=pandia/>  

The ''Zero-click Info'' section, following a search term request, displays a snippet of information from the top result for each specific search. It's intended to provide users the ability to learn about a search topic without having to click the link.<ref name=pandia/>  

Other unique features include "Category Pages," which group topics about similar concepts, and "[[Disambiguation]] Pages" in front of search result pages where applicable. An ambiguous search term with many meanings (for example, "[[apple]]"), DuckDuckGo asks the user what meaning they want, and then displays results (and ''Zero-click Info'') that is more targeted to that particular topic. For searches that contain topics within it, DuckDuckGo will detect those topics and similarly adjust search results to target them in particular.<ref name=differences/>

Duck Duck Go partnered with [[The Parked Domains Project]], which regularly crawls the [[World Wide Web|Web]] and marks [[spam]] and parked domains; DuckDuckGo omits all domains marked as spam. The search engine also uses human policed sources like [[Wikipedia]] and [[Conservapedia]], placing links from these sources (note not just to them, but from them), above algorithmically generated links. The CEO, Gabriel Weinberg, explained, "We've gone out and found entries in about a hundred other human-powered sites that are policed for spam. We use their APIs and extract the info. [...] As a result, our links are doubly controlled for spam."<ref name=fast/>
