At the bottom of the Google search results page is a link that reads, "Give us feedback." That link takes you to a form asking you to give Google feedback on the search you just experienced.
The question to many is what happens to that feedback? Does it go into a trash can? Does it get read? Does Google respond?
Google's John Mueller said in a Google Webmaster Help thread that the data from that form gets "regularly reviewed" by Googlers to ensure Google's "algorithms are doing the right thing."
I don't think Google would respond to 99% of them, but Google does say they review them all.

If you see search results that you don't find that great, I'd recommend using the "feedback" link in the footer of the search results. This data is regularly reviewed to make sure that our algorithms are doing the right thing.
And you thought they all went into some bucket that never got reviewed and was deleted daily.
It seems that Google is more responsive on reconsideration requests than this but still, Google does read these.
