DuckDuckGo

DuckDuckGo is a privacy-focused search engine: it does not store search history, does not build an advertising profile, and shows the same results to everyone for a given query.

Its index is assembled from multiple sources rather than crawled entirely in-house, so for mainstream queries results are broadly comparable to the major engines, while very long-tail or highly local searches can be thinner.

The practical benefit beyond privacy is unpersonalized results — useful when you want to see what a page actually ranks like rather than what your own history suggests. It also offers a browser and tracker-blocking extension built on the same principle.
