We have tried this network on our mobile game(450k users/10-30k per day) but its generating very poor filrates all around world. The have no statistic, and support is very bad and slow.
They generate nearly nothing.They are not able to show you fillrates, requests, sorting per region etc. One day 0,01USD and another 1USD
I definitely not suggest this. Dot trust them. Most of the ad networks of these days are cheaters.

Leadbolt is great for advertisers if you can get their formats to work (notification ads, offerwalls, icon ads etc) - major advantage over banners if you can get them to back out.

Works well for certain types of mobile offers and they've got lots of inventory.

Leadbolt is earning us good revenues - way better than admob or adwhirl. You need to add all the different formats but it works!

Leadbolt are simply one of the most innovative mobile ad networks out there. They have been first to market with a lot of new formats such as App Icons, Notification ads and so on. These type of ads really convert well for advertisers and deliver way higher CPMs for developers. You can combine their various ad formats in a single app to create multiple revenue generation opportunities. This is way beyond basic banners and really starts to provide 'mobile native' approaches to advertising. We recommend giving Leadbolt a try.
