> To do that, DuckDuckGo gets its results from over four hundred sources. These include hundreds of vertical sources delivering niche Instant Answers, DuckDuckBot (our crawler) and crowd-sourced sites (like Wikipedia, stored in our answer indexes). We also of course have more traditional links in the search results, which we also source from multiple partners, though most commonly from Bing (and none from Google).
Yes, as we know nothing about the percentage of traffic which is coming from google, bing or any of the remaining 398 ressources. I can only assume the contribution is abysmal, given the almight of the one trully.
I read that as "Over four hundred sources for instant answers (the big box at the top) etc. What you usually think of as search results ("traditional links") comes from multiple partners, mostly from Bing (and never from Google, which only leaves Yandex and niche providers)".
Doesn't it maintain it's own index on certain terms based on user actions/feedback that changes the bing results resulted? I thought there was an improvement feedback loop.
That doesn't seem to be the case; the only reason they use r.duckduckgo.com is for redirecting without the REFERER according to their docs, so there doesn't seem to be a way for them to do that.
