In my case, they never made a normal conversion, even if the traffic was organic or purchased, it does not matter. The same traffic directed to other affiliates showed great results, so I stopped using them. When communicating, they always responded with very vague messages and told me that I should send better quality traffic, even considering that I was redirecting mostly from tier 1 countries. Better to choose something more reliable that brings in a good percentage of revenue, and will be a win-win in the long run.
