Here's how it works. The ads run, and then the site gets paid nothing. Well, it only seems that way lately.
There are some ads that are paid by the number of times they are displayed. These are sometimes called "CPM" ads. Others pay based on the number of clicks. These are "CPC" ads.
Some sites ask you to click because they get paid more. Frankly, I just find it cheesy. I don't want people to click ads unless they are interested in what they see. Though I certainly appreciate your interest in helping out the site.
