I've been running smileys, fun cards ads for the last 2 years and noticing the earnings has gone way down this month. I've seen more international installs and less US installs. I'm getting 3000 clicks a day and hoping around $0.01 eCPC for these campaigns. If I replace the campaign with adsense I'll be getting at least $0.03 but I prefer CPA more than CPC. Anyone know what else campaigns work on smiley, fun card sites? Thanks for your input.
