What I don't understand about this explanation is that Google's results are abysmal compared to e.g. DuckDuckGo or even Brave search. (I haven't tried Kagi, but people here rave about it as well.) Sure, all the SEO is targeting googlebot, but Google has by far more resources to mitigate SEO spam than just about anyone else. If this is the full explanation, couldn't Google just copy the strategies the (much) smaller rivals are using?
