An article about reduced quality was pretty popular on HN a few years ago, that Google results looks like ads. But I believe we have hit a new low recently. Perhaps that is true for the overall quality of publications on the net. The amount or either approved news sites without significant content or outright click farms is immense. Even for topics that should net results. A news site filter would already help a lot, but even then the search seems to only react on buzzwords. Sometimes even terms you didn't search at all that were often associated with said buzzwords.
