The article concluded:

"Weinberg's non-ambitious goals make him a particularly odd and dangerous competitor online. He can do almost everything that Google or Bing can't because it could damage their business models, and if users figure out that they like the DuckDuckGo way better, Weinberg could damage the big boys without even really trying. It's asymmetrical digital warfare, and his backers at Union Square Ventures say Google is vulnerable."

DuckDuckGo has refined the quality of its search engine results by deleting search results for companies they believe are content mills, such as eHow, which publishes 4,000 articles per day produced by paid freelance writers, which Weinberg states to be "low-quality content designed specifically to rank highly in Google's search index". DuckDuckGo also filters pages with substantial advertising.{{cite web|url= https://www.technologyreview.com/2010/07/26/26327/the-search-engine-backlash-against-content-mills/ |title=The Search Engine Backlash Against 'Content Mills'|last=Mims |first=Christopher |date=July 26, 2010 |work=Technology Review|access-date=March 19, 2013}} DuckDuckGo down ranks websites deemed to have low journalistic standards.{{Cite web|url=https://github.com/duckduckgo/duckduckgo-help-pages/blob/29642f2e966299f9240f0dd73bfbf95e86dc7a64/_docs/results/news-rankings.md?plain=1#L37|title=duckduckgo-help-pages/_docs/results/news-rankings.md at 29642f2e966299f9240f0dd73bfbf95e86dc7a64 · duckduckgo/duckduckgo-help-pages|website=GitHub}}

In addition to the indexed search results, DuckDuckGo displays relevant results, called instant answers, on top of the search page. These Instant Answers are collected from either third party APIs or static data sources like text files. The Instant Answers are called zeroclickinfo because the intention behind these is to provide what users are searching for on the search result page itself so that they do not have to click any results to find what they are looking for. Instant answers are created by and maintained by a community of over 1,500 open source contributors. This community has come to be known as DuckDuckHack.{{Cite web|title=DuckDuckHack |url=https://duckduckhack.com/ |access-date=October 29, 2020 |website=DuckDuckHack|url-status=dead|archive-url=https://web.archive.org/web/20221003005208/https://duckduckhack.com/|archive-date=2022-10-03}} {{As of|July 2019}}, there were 1,236 Instant Answers active.{{cite web |url=https://duck.co/ia |title=DuckDuckGo Instant Answers |access-date=July 7, 2019}}

In the DuckDuckHack documentation, four types of Instant Answers are described: Goodies, Spices, Fatheads, and Longtails. These types of Instant Answer extensions are differentiated by how their data is retrieved. Goodies do not retrieve data from a third party API, whereas Spices do. Goodies instead use some form of the aforementioned static data sources, such as text files or JSON files. Fathead Instant Answers are key-value answers hosted on DuckDuckGo's backend. Fathead key-value pairs function similarly to a trigger for showing the respective Instant Answer. Longtail Instant Answers are full text queries to a DuckDuckGo database of articles. Paragraphs or snippets from any matching articles are returned, and the section that matches the user's query is highlighted.{{Cite web|title=What Type of Instant Answer |url=https://duckduckhack.gitbook.io/duckduckhack-docs/determining-ia-type |access-date=October 29, 2020 |website=DuckDuckHack Docs}}

In a June 2011 article, Harry McCracken of Time commended DuckDuckGo, comparing it to his favorite hamburger restaurant, In-N-Out Burger:

{{blockquote|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 DuckDuckGo ... is really good at bringing back useful sites.

Thom Holwerda, who reviewed the search engine for OSNews, praised its privacy features and shortcuts to site-specific searches as well as criticizing Google for "tracking pretty much everything you do", particularly because of the risk of such information being subject to a U.S. government subpoena.{{Cite news|url=http://www.osnews.com/story/24867/DuckDuckGo_The_Privacy-centric_Alternative_to_Google|title=DuckDuckGo: The Privacy-centric Alternative to Google|date=June 21, 2011|last=Holwerda|first=Thom|publisher=OSNews|access-date=March 19, 2013}} In 2012, in response to accusations that it was a monopoly, Google identified DuckDuckGo as a competitor. Weinberg was reportedly "pleased and entertained" by that acknowledgment.

In November 2019, Twitter CEO Jack Dorsey revealed his preference for using the DuckDuckGo search engine rather than Google, stating, "I love @DuckDuckGo. My default search engine for a while now.

DuckDuckGo has defended itself from the criticism, saying that "The primary utility of a search engine is to provide access to accurate information. Disinformation sites that deliberately put out false information to intentionally mislead people directly cut against that utility."{{Cite tweet |number=1501716484761997318 |user=yegg |title=[...] #StandWithUkraine️ At DuckDuckGo, we've been rolling out search updates that down-rank sites associated with Russian disinformation (1/4) |author=Gabriel Weinberg}}{{cite web |last=Kan |first=Michael |date=March 10, 2022 |title=DuckDuckGo to Down-Rank Sites Associated With Russian Disinformation |url=https://www.pcmag.com/news/duckduckgo-to-down-rank-sites-associated-with-russian-disinformation |access-date=March 11, 2022 |website=PCMag |publisher=}}

DuckDuckGo also said that there were problems with "site:" search queries used for these websites and other searches and said that the problem had been fixed.

In May 2022, a report from Bleeping Computer by security researcher Zach Edwards found that DuckDuckGo Private Browser allowed Microsoft's trackers to continue running while visiting non-DuckDuckGo websites, unlike Google and Facebook trackers, which were blocked. In response, Weinberg said that "unfortunately, our Microsoft search syndication agreement prevents us from doing more to Microsoft-owned properties. However, we have been continually pushing and expect to be doing more soon." He also said given that most browsers "don't even attempt" to block third-party scripts from loading, users would still be safer than on other browsers. In August 2022, DuckDuckGo began blocking Microsoft's trackers, saying that the policy preventing them from doing so no longer applied.{{Cite web |date=2022-08-05 |title=Web Tracking Protection: DuckDuckGo's Privacy Promise |url=https://spreadprivacy.com/more-privacy-and-transparency/ |access-date=2023-05-21 |website=Spread Privacy |language=en}} Today, DuckDuckGo continues to open articles through MSN, similar to how Google utilizes AMP.

In December 2024, DuckDuckGo criticized Google's proposed remedies in an antitrust case related to search engine monopolies. According to DuckDuckGo, the proposal maintains the existing balance of power rather than fostering genuine competition. Gabriel Weinberg, CEO of DuckDuckGo, stated that the proposed measures "attempt to maintain the status quo" and are insufficient to grant smaller players fair access to markets.{{Cite news|url=https://www.mlex.com/mlex/articles/2277183/duckduckgo-says-google-remedy-proposal-in-search-monopoly-suit-attempts-to-maintain-status-quo|title=DuckDuckGo says Google remedy proposal in search monopoly suit attempts to maintain status quo|work=MLex|date=December 21, 2024|access-date=December 24, 2024}}
