Leadbolt? Anybody doing volume with them?

Hey guys!

I’m having a hard time getting any decent traffic from Leadbolt .. I can barely spend $20 daily on each campaign.

I have 320×50 banners and text ads in the campaign and I tried skyrocketing my CPC and making the budget unlimited with no different results.

My question is, Can anybody get good volume out of them? Because I’m sure they do. Not sure what am I doing wrong.

Thanks
