How can DDG make a living at 350 queries per second?

260 qps to be exact. That is not negligible.

Well, it's pretty small. I'm just multiplying though here the CTR and the CPC and the QPS. I guess they can probably serve DDG from a handful of machines, since they don't own the search stack.

Yeah, but they pay for the web results
