Why Traffic To These Google Alternatives Is Soaring by Adam Tanner, Forbes (Feb 10)
In early 2013 traffic doubled at Ixquick and Startpage and climbed at DuckDuckGo. Mind – Google in December 2013 still had 67.3 % of the US market at 12.3 billion searches a month – and DuckDuckGo around 135 million.
How do these privacy friendly sites work? Startpage uses Google results which it buys from the company (in a slightly less user friendly interface); its sister company Ixquick, as well as rival site DuckDuckGo, present results compiled from a series of different search engines. For example, DuckDuckGo says its sources are its own web crawler, Yahoo!, Yandex, WolframAlpha, Bing and crowd-sourced sites such as Wikipedia.
Google declined to answer Adam Tanner’s questions about privacy and Google’s use of search records.
