Affiliate works on the CPI model, so the payment is made for the unique installs. In this case every new banner display is a different application, so you can get 2 or more installations from one user. Unfortunately, the system does not allow to see promoted offers.
I've tested a lot of ad networks and advertising mediation Appodeal. I can say about AdtoApp – that it's the most profitable and convenient mediation for a developer. High eCPM, 100% fill rate! Payouts are once a month! Profits are 20-30% higher than those of Appodeal.
They cheat with displays. I go to the site from a mobile, I see that advertising is running, but in the there’s statistics nothing at all. Attendance - 1500 hosts per day. I’ve written to technical support, they say, where is your advertising, in the statistics there is 0.
In reply I got the following: "In recent years, advertising traffic for Russia significantly decreased, as a consequence of which the banner ads on the sites, the traffic of which is mainly from Russia, have been displayed very infrequently. Our specialists are already dealing with this problem and everything will be resumed in the near future, I apologize for the inconvenience.
