I see what you are driving at. However, Google is a $33 billion company, yet I made them exactly $0 through ads, which is their primary business. In my mind that means that someone must be clicking on those ads, and I'm sure it's not me.

Google earns money just because someone shows you the ad. And if I'm not mistaken, when you click in some ad, the site showing it also earns money.

So, basically, people spend money anyway, but you just "reward" the site when you click on it.

You are a set of eyeballs or "impressions." Maybe you won't click on the ad, but you were displayed it, which is a success in and of itself.
