I am looking for a CPA offer to promote, but I would like to know which one is most profitable with the highest conversion rate and highest payment per action. Any help would be appreciated. Thanks.
Have you tried sorting the data offered by your CPA network? For example, one of the networks I use is Neverblue, and you sort campaigns by EPC, by commission and so forth. I'm fairly sure I can do that with my other networks as well. Every network will have it's own campaigns so it's kind of hard to tell you what is the best one to offer.
I am getting awesome returns from Motive Interactive on an insurance CPA offer. All that's required is a zip code and to answer whether you already have insurance or not. Payout is a whopping $3.75 per 1 page submit.
Usually they require you to at least be somewhat established, ie have one decent website. Not that you have to have tons of visitors every day, but at least something to show what you will be marketing on.
