While I agree, like said above staying anonymous requires much more than just a good Search Engine. which DuckDuckGo is the one i agree on, once again I suggest you use the Tor browser so that your proxy is all over the place and not directing as much back at you. I don't mess around too much but I know there is a lot more to it such as custom router firmware/etc. Also using a solid VPN I use Private Internet Access but there are quite a lot available. Many of these VPN companies keep logs, so ensure that the one you choose to use doesn't. Beyond that it just gets more and more complicated.
There are ways to spoof HWID but at the end of the day Idk that it would be the most effective and if you don't know what you are doing there are many risks.
I might not be 100% but a lot of these things I've used, I'm just a hobbyist so take it with a grain of salt.
