The lack of an ability to vote on search results seems like a baffling omission. Normally Google loves to crowdsource their work, but for this one area where we would actually want it, they decide that they know better when they clearly don't.
But you do vote on search results. Google knows if you stay on a page or leave it quickly for another result. That's an implicit vote that they definitely take into account. Having that explicit button might not really add any additional value.
Especially for use cases like reviews where you are looking for multiple opinions.
The hard to navigate site full of waffle, and SEO duckspeak nonsense gets a positive while the site with clear concise information the user can absorb in 2s gets penalized.
