If a user is looking for something in particular and then clicks on an ad, in all likelyhood he/she will remain on that site if it satisfies what they were looking for. They are going to forget to go back and click the button that suggests the page was useful.

The only people that are going to be clicking the back button are those that are unsatisfied, because they need to find something else on the SERP page. Since they are the only ones that are likely qualified to answer the question at hand, it stands to reason that the maority of the feedback will be negative, no?
