Hi, I need to find a STABLE traffic source. That means once I found a profitable compaign I want to be sure, that nothing will happen with the traffic over time. It shall not get worse, or less, or something else not desirable. My first thoughts are: a SINGLE traffic source like fb or youtube/ google might be better, because in this one source probably not so much can happen. But when you go to an ad network, this network is giving you traffic from many different sources. So there are more variables, which you cannot control. So, changes may occur faster and you cannot do much against it. My thoughts are right? Any other ideas which traffic source stays stable over time?
