The problem is Google has no competition, and thus no incentive to improve the product. However, if my understanding of the Chinese market is correct, the Chinese Google (Baidu.com) doesn't seem to hold hostage the Chinese internet the way Google does. I'm not sure exactly why but maybe the Google killer isn't a general web search engine at all. It's looking more and more like Reddit could even be the Google killer, albeit unintentionally.
I also want to give another anecdote: one of our biggest marketing categories revolves around pets, and despite it actually being a large chunk of our sales (and therefore implicitly relevant), when you search google for keywords relating to our product and "pets" we don't even show up until page 7 or 8 despite being exactly on topic. The people who do end up finding about us are searching for other keywords unrelated to pets and converting to paying customers. This is implying if they searched "on topic" they aren't getting the results they want. While there are other keywords where we do show up, it pretty much shows how poor Google is at actually ranking websites these days unless one specifically pays for SEO (buying links on spam sites for popular keywords).
So for a commercial keyword "[our product] + pets" there's so much spam we're lost in the fray. But for a non-commercial keyword that we also have relevancy for "AI + [our product]" we actually rank easily on the first page for, since nobody is selling anything. Maybe the key here is to just create a better search system for commercial products and services, since Google works relatively well when on topics where there is no incentive to spam.
