Hi Friends, this is my first posting here! So I hope I have posted in the right category. So, I have my own network of domains that receive steady traffic from all around the world. Recently I got banned from adsense and so in order to keep the system running I had to shift to other ad networks preferably CPM based networks. There are over 100 domains and so placing ad codes on each one of them is seriously tiring. So how can this be addressed? I know nothing about ad servers. Which ad server is free and can be good for my scenario? Any CPM networks that you would recommend?
