Probably like Dogpile.com. It may just pull from Google.
I use duckduckgo and I’ve been meaning to research other alternatives, but my main gripe with google isn’t their politics, which is pretty craptastic on it’s own, nor even their egregious record on personal privacy, but how they augment search relevance based on who buys ads.
I understand that this is their business model and most people probably think it’s fair, but I think that when you have a market stranglehold on internet searches and your not going to get busted for being a monopoly, then you had better at least provide a fair, unbiased service. I never had any problem back in the days when google simply places paid advertiser’s ads above the search results. That was fair. I feel that it’s corrupt to alter search result’s relevance based on monitization without showing the public how the results are being affected.
