Well not using Google or at least not directly. Besides alternative search engines with their own engine, there are also meta search engines that utilizes Google and probably other unique engines as well. This does not solve all problems, but at least you don’t get the ads from Google and won’t get tracked by Google either (so searches are not limited to your region or what you searched already).

And in case of the open source meta engine Searx it will show results from multiple engines and display from which engine the results are. All without the ad nonsense. And while being able to configure it the way you want. My point is, you don’t have to use Google directly or at all.
