Google is definitely iffy for me, which is why I've been bouncing between alternates. A lot of people like to complain about how google is filled with ads and spam results like Pinterest, but even then it just doesn't really seem to give accurate results anymore, and even when results are accurate it's very surface level. From what I found, it loves to push listicle articles and such when googling a new topic, as opposed to say, Wikipedia or an encyclopedia article. Like if I search about Barbie, I'll probably get a bunch of ScreenRant-esque articles before I get the IMDB page. There have been dozens of instances of me searching for controls for video games and getting clickbait-y articles, some of which barely even make an attempt to answer the question, before getting an IGN or GameFaqs article that's to-the-point and answers my fucking question.

There are definitely better search engines out there, but they all have their own flaws. DuckDuckGo is pretty bare bones and can also give poor results if your search is too vague. You have to adapt to that one. Others like Brave have AI to help out with summaries and stuff, but Brave's management is "problematic" and so some people might not want to support them.

TL;DR: on google, not only is there ads and spam, but it's just hard to find answers anymore. Everything is clickbait. And with other options, they are good but they also have their own major flaws that some might find unappealing.
