As practice has shown, affiliate networks like to change their offers SUDDENLY! And sometimes they even forget to you notify about it. All of a sudden you may find that the payment has fallen down beyound the limits or the traffic is flowing nowhere.
Of course, you can follow the news of all the networks you are interested in manually, looking at them every morning and checking for updates on your offers. Especially when you work as a reseller or as a team, and you have a thousand offers. Or you can monitor social networks in which affiliates post their changes - Facebook, VK, Twitter,
Tinder, MySpace and a dozen more. And look for accurate data on the news "Payments for dick extender changed!", trying to find out what kind of rates, for which countries and which cream have changed.
Agree, it is much easier when all the changes flow in one place? But the most interesting thing is that they are doing it absolutely free for now.
