Hi all, and first of all, thanks for your answer.
I´m just about to launch my first campaign, and im reviewing the traffic sources. I want to run mobile camps ( branded, utility apps and sweepstakes) in TIER 3 countries.
I think to sing with Go2Mobi, CPAlead and Avazu.
Any other recommendation, about sources or type of vertical/promo?
Thanks
Avazu and Go2mobi are great for sweeps promotion (specially Mobfox exchange) and also utility apps. Check out also PopAds, PopCash and Propeller for app installs and sweeps.
Thank you @antuen
