>DDG is Bing

Eh? Maybe you are saying that because they serve ads from Bing?

From https://en.wikipedia.org/wiki/DuckDuckGo :

>DuckDuckGo earns revenue by serving ads from the Yahoo-Bing search alliance network and through affiliate relationships with Amazon and eBay.

>In July 2016, DuckDuckGo officially announced the extension of its partnership with Yahoo! that brought new features to all users of the search engine, including date filtering of results and additional site links. It also partners with Bing, Yandex, and Wikipedia to produce results or make use of features offered. The company also confirmed that it does not share user information with partner companies, as has always been its policy.

As far as I know (hence I could be wrong), that’s outdated. Since Yahoo was purchased by Verizon, it is predominately Bing results with some Yahoo/Oath/Verizon Media results sprinkled in, considering it now predominantly uses Bing itself. Yandex is no longer used and Wikipedia is just part of their knowledge cards or whatever they call them, like StackOverflow is. In other words, it’s mainly Bing with DDG’s own crawler used specifically for the knowledge cards and to modify the priority of results pulled from Bing.

With that said, I do believe they have a special deal with Microsoft to not pass along any information. Instead, the only information Microsoft sees is DDG requesting the results on behalf of the users (aka Bing/MS just sees DDG’s IP, etc. which can be seen sometimes in the results, not the knowledge card, when you search for “what’s my IP” in DDG). My one gripe though is that they’re definitely not as transparent as they could be about where and how they source results.

AFAIK They use bing for [almost] all search results and yes, they seem to try to be vague about it on purpose.

Maybe someone from DDG could clarify this?

DDG is basically a reskin of Bing search.

DDG claims to aggregate Bing, Yahoo, and Yandex, but Yahoo switched to Bing a decade ago, and Yandex is only really relevant for Russian-localized websites.
