Which are the best Mobile Traffic sources?

[white knight]

These are basically apps for finding restaurants, GPS guide etc.

So, we want suitable mobile traffic source for them. Currently we are running fb sponsored ads.

Media.net is also good. But it is great only for North American and Western European traffic.

If you don't have serious big budget then I wouldn't recommend media.net

Their campaigns need to get paced to work and for that you need money first.
