Google used to be really, really good at finding exactly what I told it to find. Nowadays, it's turned into the yellow pages; sponsored content from businesses trying to sell me goods and services.

Can people suggest good alternatives or search patterns for certain categories of information or search types?

Some of the search patterns I currently I use:

* Youtube for product reviews and demos, entertainment, music and educational material.

* Google with site:reddit.com at the start for questions best answered by other humans; crowd-sourced answers, authentic replies from mostly real people.

* Google with site:news.ycombinator.com if I want to find "forum-like" discussion on topics I'm interested in.

* Google Image search with site:amazon.co.uk when looking for niche products I need to buy, because Amazon's search is so incredibly broken and game-ified.

What I'm having a heck of a time finding is technical content; long-form programming tutorials, deep dives into academic concepts (I do a lot of signal/audio processing and search for blog posts related to these topics), circuit schematics, electronic engineering content. These used to exist on enthusiast forums 10-15 years ago, but Google often no longer surfaces hits from these forums, both because the content is old and the forum model is dying. Reddit is the "replacement" but it plagued with low-effort "look at my thing" posts that help nobody.
