This already exists. If you navigate back to the search results then that counts as a downvote. If you don't navigate back, that's an upvote.

I know this is true, but my use of tabs means I've opted out of the system.

I open tabs for the top results and just close them when done. Often, I have to re-search with added "verbatim" filter or quotation marks because Google seems to ignore my most important keyword 90% of the time.
