It is $~0.3 per 1000 of globally unique impressions, that correspond roughly to 45K non-unique impressions, or $0.02 per click. Advertisers, advertise!
I find the interface a bit fiddly! It's not the easiest site to advertise on, I've always stopped just short of actually sending the coins over.
I think the interface needs an overhaul! Other networks like MellowAds are taking things over.
Thanks for your feedback! It is supposed to take less than a minute to create an advertising campaign: http://a-ads.com/campaigns/new
Cold you please highlight particular problem with it?
