Had a question in general. Finally having some success with a CPA effort. I'm running it on 2 sites in the same niche, one with adsense, one without. The one without is still too new to be able to tell if I have more sales there than the one with adsense where I give the viewer an "out" that is not buying the product (ie clicking the Google ad(s)). That site has made some decent sales, about 30% adwords driven, the others from organic search. The new site has made sales only from adwords.
My first thought is that its better to keep the site with no PPC/adsense, free, but am I losing revenue by doing so? Anyone else who is successful with CPA combine the two out there?
