This is possibly something you could implement in a meta search engine like SearXNG, though there are some privacy concerns.

Maybe it could locally store which domains you personally tend to click (and stay) on. Then automatically raise those domains when it sees them somewhere in the output of the underlying engines. This isn't perfect because you wouldn't get data from other users. But I think it could do a lot to improve search results.

I might actually clone the repo and see if I can get somewhere soon
