Hello there guys. I've just ran into some problems and am looking for somebody with experience. So, I've ran a couple campaigns on PropellerAds. On first and seconds campaigns I used Google Analytics to track my traffic. With the CPM of 1.3 to 2$, in the propellerads dashboard I've seen a number of 5-10k impressions for each campaign (depending on the budget). On GA I saw like 300 unique users... I messaged them and they said that GA tracks PopUnder clicks incorrectly. Okay... I created another campaign. I've setup Yandex Metrika on it and my own simple node.js server to track user activity. Both YM and my server showed results ~ 20 times less than the number I saw in the propellerads dashboard. So, seeing like 8k impressions on propellerads dashboard, I got like 400-500 unique IPs/users in Yandex Metrika and my own server. Again, they said YM can show stats incorrectly and they also ignored that I wrote about my own server counter. They said to use something like Voluum to track impressions. Though I don't think it would show something better, since my server has been counting impressions so simple, just like when a user loaded a page I automatically sent a message to my server and tracked him. I could understand ~50% of traffic loss (though it wouldn't be cool) , but not 90%?! Am I wrong? Can someone put his own experience here? Maybe advice about another popunder/popup/whatever traffic source? Why should I pay like 5-8$ CPM if 1-2$ CPM shows only 5-10% of all impressions, I don't believe something would change with a higher CPM. CPM rate determines if my ad will be shown or not if there is another competitor, so there is no way I could lose 90% of my paid traffic. Thanks in advance guys!
