I've decided to make an experiment with a CPA offer. Why? I was just curious if everything works as it should be. So here is the setup. Dating offer that converts on first page submit, US, no age restriction. I basically copied the page of the offer and put a simple PHP script that will catch the information filled in the fields. That's all. Wondering what the results was? Sending traffic for about 30-40 minutes - got 23 clicks and 4 conversions on my page where the script is. Checked the IPs, the information that was entered(all of it was valid) and I was sure these was 100% natural conversions. Then I've swtiched to one of the CPA networks that I'm using. The result was horible! 68 clicks, not a single conversion! Tried with another network - almost the same result. You didn't wait long enough or your traffic wasn't that good at this moment, you'll say. Well, I know that my traffic converts good because there is really good call to action before send the user to the offer. So I believe if I got 50 conversions per day in a network, I probably made about 65-75 if not even more. The points is... how can I trust my networks now? I'm sure if I continue with this experiment, I'll see really bad and sad things/results. I won't mention which networks I've used for this since it can be advertiser that shaves the leads. But no matter what, I'm screwed and it sucks! If you doubt in your network/advertiser go ahead and copy what I did to check if they shave you too.
