Also, I find that basically every search result that isn't reddit is sponsored content.

Search something real specific like "Best aftermarket injector coils for a 2009 Toyota Corolla" and you're going to get 100% advertisements and listicles for search results, likely written by somebody who doesn't know shit about cars.

Append "reddit" to that search, and you'll be led to a post from a car mechanic giving their opinion on the matter. And, well, I do trust a random stranger on the internet more than I do an advertisement.
