There are way too many factors that can affect EPC. Google hides how things really work for us so you don't know if the old traffic is still getting the same EPC. When you get more traffic is it all quality traffic? Does your new traffic come from repeat visitors or only first time visitors? Does your new traffic come from new pages or the same old pages? Also I am wondering if google gives better to non google traffic. Another item we have no idea about is smart pricing. It is near impossible to find out how adsense does things. All we can do is do whatever gives us more money at the end of the day.
