One of my sites, that gets about 15 Adsense clicks a day, use to bring about $0.40 a click. Recently that amount has dropped a lot. Over the last couple of days, all clicks on that site are only bringing about $0.05 - $0.10 per click. A trend that I have seen is as traffic increases on the site, the revenue per click drops. Is this normal? Are there other reasons that may cause this?
I would say that you are a lucky man... in my point of view obviously But yes it must be smart pricing.
