Hey,
so I have been recently experimenting with many traffic sources and trying new ones every day. What i have found out that even if I make a campaign profitable, after cutting all the pubs and optimising variables the amount of traffic is not enough to make it a x,xxx / xx,xxx a day campaign.
What are the sources you use for scaling (pops, display, interstitials, anything really)?
I have heard good things about AdCash, what else is there in order to hit the bank?
With mobile you can make almost any campaign profitable. The problem is that if you have to do so much optimization that there's very little traffic left in the end. There's nothing more draining than running "baby campaigns" on 20 different ad networks.
Focus on campaigns with wide appeal and/or broad targeting. You won't hit $10k/day if you target 2 carriers on Android in Brazil.
Almost all the major ad networks have enough traffic to do $10k/day if you target broad enough - Airpush, Decisive, Exoclic, Millenial, inMobi, Leadbolt (USA for volume) and there are a few more
