Depending on the topic and search query it at least has become harder to find information written by actual human beings, and not some garbage sites 100% created and designed for SEO. These sites typically contain lots of generated (or at least mindlessly typed) filler text. Sometimes they have some information inbetween this gibberish, sometimes they completely look like they came out of a markov chain generator.

Because of this it is often necessary to append something like "reddit", "forum", "wiki", or "news" to my search, lest I only encounter SEO trash.

I believe I can estimate with confidence that Bing and DuckDuckGo are nowadays better than Google during half of my searches. And that was certainly not the case 2 years ago.
