Possibly. Part of Google's advertising revenue comes from AdWords and YouTube ads. This revenue is split with content creators, enabling them to invest in more and better content to the benefit of their users.

More search ad revenue allows Google to invest more in search. Better search could benefit content creators by giving them more and better targeted users. Users benefit from better search because they are able to find the content they are looking for faster.

I'm skeptical that Google divides its revenue and investment up in this way and that more search ad revenue allows Google to invest more in search.

I'm sure that Google is already investing the amount they need to in search to make it as profitable as possible.

It seems that more search ad revenue allows Google to bank roll the rest of the Google/Alphabet behemoth on projects unrelated to search, but within its mission to "to organize the world's information and make it universally accessible and useful" ie. to know everything about everything, which I'm sure tracking plays a role in.

and that's become an abusive relationship where they are being de facto censored by google because of advertisers being skittish. You have more sponsored content showing up because it's a lot easier than relying on google and their amazing algorithms to not screw you over.
