I think we have loads of tools to play with but fundamentally there is a problem when you are fighting with your search engine to find stuff you want to find.
My laptop (Arch) still has Chromium as default with uBlock Origin, Privacy Badger, uBlacklist and a few others running. I will be moving back to FF and running a sync server because I am that pissed off and able to do so. I'll also take a few others with me (between 2 and rather more)
When I say move back to FF, I'm talking about something like reverting a 10-15 years change.
I've always had FF available but it fell short back in the day for long enough for me to move to the Goggle thing. Now I think I'll go back.
Noone at G will lament their loss, I'm not even a rounding error. I'm sure that all is fine there.
If you're referring to user-curated search result blocking, that's very easy with DuckDuckGo and uBlock Origin (just block elements like [data-domain="w3schools.com"]; see my comment to the GP). I don't know of any large extant lists like this though.
That won't do much if every result on the first page is blocked. Ideally a filter list like this could be pushed to the server side as a per-user preference to go with your query, so that if e.g. the top 10000 results were all filtered out, then you wouldn't have to click through (or infinite-scroll autoload) 100 empty pages before getting anything.
DDG will add more results, if enough are hidden. If I search "w3schools" with my filter, there are only two results on the first page that are not hidden, so it immediately displays the second page below. It seems that they planned for this use case.
I used to have an automatic google search-domain blocker. It was just front-end though so if a page would have website domains that were useless, it would only have 1 or 2 results on it unfortunately. Something a little better integrated would be nicer.
