I'm imagining the site deals with fairly significant load- the game is incredibly well selling and most players need to look things up. Would make a great article on infrastructure for a group that doesn't have a visible funding model.
I don’t know what’s going on at Google but the search engine quality has dropped off a cliff in the past 6 months.
What they need to improve search quality is the intelligence to identify things as spammy and low value and then drop the rank of all the SEO optimized crap that people hate.
I can only imagine that google sees this as politically impossible ("you destroyed my business, Google! I'm gonna sue!") or they have decided the return on investment simply isn't there. They do not need to give you better results to keep getting search queries that help them to show you ads.
Experts on a given topic have no need to continuously spam their sites full of minutely modified "best of x in April 2022" listicles. They were authoritative when they published their views ten years ago, and they're still authoritative today. Google doesn't care. Ten year old information isn't relevant or useful.
