Some people believe that it does, that's why they pay users to search for something and click through the serps & go back until they arrive at the target domain where they don't click back but stop the experiment, signalling that this page answered their question / solved their problem.

I've seen some data on this, and that data was inconclusive. Sometimes it seems to work, sometimes it seems to be counter-productive, sometimes nothing happens. It's hard to truly test things in isolation, and maybe their methods were shit, but I don't think it really does anything, or maybe Google has solid ways to detect anomalies and ignore them.
