While the name has been called "silly", when questioned about the name, Weinberg has explained, "[r]eally it just popped in my head one day and I just liked it. It is certainly influenced/derived from Duck Duck Goose, but other than that there is no relation, e.g. a metaphor."

, the DuckDuckBot. It uses data from crowd-sourced sites, especially Wikipedia, to populate "Zero-click Info" boxes, which are red boxes containing topic summaries and related topics above results. DuckDuckGo also offers the ability to show mostly shopping sites or mostly info (non-shopping) sites via search buttons on its homepage.

DuckDuckGo positions itself as a search engine that puts privacy first and as such it does not store IP addresses, does not log user information and only uses cookies when needed. Weinberg states "By default, DuckDuckGo does not collect or share personal information. That is our privacy policy in a nutshell."

Weinberg has refined the quality of his search engine results by deleting search results for companies he believes are content mills, like Demand Media

In August 2010 DuckDuckGo introduced anonymous searching, including an exit enclave, for its search engine traffic using Tor
Tor (anonymity network)
Tor is a system intended to enable online anonymity. Tor client software routes Internet traffic through a worldwide volunteer network of servers in order to conceal a user's location or usage from someone conducting network surveillance or traffic analysis...

. This allows anonymity by routing traffic through a series of encrypted relays. Weinberg stated: "I believe this fits right in line with our privacy policy. Using Tor and DDG, you can now be end to end anonymous with your searching. And if you use our encrypted homepage, you can be end to end encrypted as well."

In 2011, DuckDuckGo introduced voice search for users of the Google Chrome

 "Voice Search" extension.

DuckDuckGo also features !Bang commands which give the user the ability to use DuckDuckGo and have their search redirected to the relevant site. An example of this is the !wiki command which redirects the search to Wikipedia's English website.

Reception

In a June 2011 article, Harry McCracken of Time Magazine was very positive about DuckDuckGo, comparing it to his favorite hamburger restaurant, In-N-Out Burger
In-N-Out Burger
In-N-Out Burger is a regional chain of fast food restaurants with locations in the western United States. Founded in 1948 by Harry Snyder and his wife Esther, establishing the first In-N-Out burger in Baldwin Park and headquartered in Irvine, California, In-N-Out Burger has since expanded outside...

, "It feels a lot like early Google, with a stripped-down home page. Just as In-N-Out doesn't have lattes or Asian salads or sundaes or scrambled eggs, DDG doesn't try to do news or blogs or books or images. There's no auto-completion or instant results. It just offers core Web search—mostly the "ten blue links" approach that's still really useful, no matter what its critics say...As for the quality, I'm not saying that Weinberg has figured out a way to return more relevant results than Google's mighty search team. But Duck Duck Go...is really good at bringing back useful sites. It all feels meaty and straightforward and filler-free..."

and its shortcuts to site specific searches. He stated "...what are some of the reasons you might want to try out DuckDuckGo? First of all, DuckDuckGo doesn't track you, so you get real privacy when you search the web. Google tracks pretty much everything you do so they can better target you with advertisements. I have no problems with targeted advertising...What does bother me, though, is the fact that I wouldn't be able to protect myself if the US government ever subpoena'd Google to gain access to that information....More importantly though (at least for me) - DuckDuckGo tries to pop something called the filter bubble."
