Jovan StosicDuckDuckGo (DDG) is an internet search engine that emphasizes protecting searchers’ privacy and avoiding the filter bubble of personalized search results. DuckDuckGo distinguishes itself from other search engines by not profiling its users and by showing all users the same search results for a given search term. It emphasizes returning the best results, rather than the most results, generating those results from over 400 individual sources, including crowdsourced sites such as Wikipedia, and other search engines like Bing, Yahoo!, and Yandex. As of October 2019, it had 47,225,192 daily searches on average.
The company is based in Paoli, Pennsylvania, in Greater Philadelphia, and has 67 employees as of July 2019. The company name is a reference to the children’s game duck, duck, goose.
Some of DuckDuckGo’s source code is free software hosted at GitHub under the Apache 2.0 License, but the core is proprietary. The company registered the domain name ddg.gg on February 22, 2011, and acquired duck.com on December 12, 2018, which are used as shortened URL aliases that redirect to duckduckgo.com.
