DuckDuckGo is very good, as is Startpage, and you sometimes get different results with that one. They make their money by carrying ad-search hits (or whatever they call them), so that, if you search for 'Lawn Mowers', your first hits for that one single search will be for lawnmowersrus and mowers.com, but it's entirely up to you whether you click on them or not, and they won't follow you around the web if you ignore them. I think Startpage uses Google, but it acts as a proxy so that, instead of Google knowing what User123 is searching for, they only know what 10 million things 10 million different unspecified users are searching for right now as a group.
What a lot of people don't know is that any site that has a button to click on to share with FaceBook, Twitter, Insta or whatever (almost all websites) has a permanent link to those SM sites and what you do on the site will be shared with them and monetised if possible, even if you don't click on them or even necessarily have an account with them.
It's apparently all done for your convenience, of course. Amazon are now 'kindly' offering you a 'handy' feature whereby you can let them track every single thing you do online and then exploit that information to bombard you with adverts for what its algorithms determine are associated products. They didn't use quite those words - but they actually try and push it as a benefit to you! Can you imagine that in the real world? Somebody offering to follow you around, listen to everything you say, open all your post for you and look through all your cupboards and offer 'helpful' purchasing suggestions as a result?!
I haven't looked into it, but I hear there's a different search engine called Everyclick, which donates money to your nominated charity for every search you make. Hmmm, wonder how they make the money to be able to do that....
What always irritates me is, when just about every website tells you about the cookies they set (as they legally have to) and hopes you will click on the massive bright, flashing 'OK' button rather than the tiny little line of grey text that says 'more options', they almost always claim that 'Your privacy is important to us'. Yes, in the same way as your handbag is important to your friendly local mugger in the park.
