"which means that the advertisers are paying PER CLICK not a fixed amount of money."
On a Pay Per Click basis, IMHO no visitor with an "ad-free" browser should be counted as a "view". With Firefox and Adblock/Noscript installed this site is completly "clean".
I'm new here (6 weeks) and my content has generated ~45000 views last month. So there should be at least 45000 * (ads per page) more than the month before. We'll see what comes out next month.
