I don't advocate for their content but the way they've built things is pretty great.
I've described it as "the 1998 web with better cgi scripts".
Also search engines like marginalia (https://search.marginalia.nu) and teclis (https://teclis.com/) are nice - they essentially filter out pages with advertisements and trackers which is a pretty brilliant way to defeat SEO farms and other low quality content with ulterior motives.
To see their effectiveness give it a challenge. Try queries like "how to lose weight" or heck, "lasagna recipe".
To demonstrate, I just took the time to make two videos for "lasagna recipe" with the network tab of chrome's inspector window open:
google's first result: https://www.youtube.com/watch?v=ntC5ZcgxyD4
teclis: https://www.youtube.com/watch?v=GULoL8o6NDA
Along with recipe sites, there's recently been a crop of similar looking tech help sites that basically give w3schools level answers with a bunch of rotating ads based on the hypothesis that users will look at the content, then focus on their work for the next hour or two, keeping the tab open because that's just the common pattern while the ad rotations go on the page.
As far as serving ads go, programming and recipe sites exhibit similar usage patterns. Similar to recipe sites, the answers you came for are interleaved with ads in the hope that people drag their cursor over the banner ad while selecting text from the site or at least keep that part in the viewport open for the duration of the activity. What a lovely feature!
Search has to be driven by axioms of values and purpose because different intents yield different results. There is no silver bullet.
For example, google, bing and yandex's goals are pretty antithetical to mine unless I'm actively trying to buy something. On google, I came for a lasagna recipe and someone tried to sell me car parts and a home mortgage which is fine. Those engines are just a poorly chosen tool for that job.
