I bought a niche website, which is wordpress based with a few good articles. With this i get few clicks here and there due to low traffic. But the CPC is good. For desktop traffic. I made a HTML simple one page website to test affect on CPC. On the HTML page I just copied the article from the wordpress blog. I then added cookie notice and 2 adunits. I found that sending traffic to this html page got me much lower CPC (like 50% lower). Why is this? Does the type of site affect the CPC?
