doese the advertisers on popads choose directly which site to show their ads on? i readed about bidding in their site but don't fully understood how its work. i have an adult blogger blog and use popads to show pop-unders on my site(started with popads two days ago), but it doesn't seems like i get any money, i got only 0.02 dollars and its quite low even for a blog with only around 200 pageviews perday, shouldn't i get more than that or its all depends on the advertisers themselves?. should i just wait for someone to start advertising on my blog? anyway what popunders do my watchers get when they use my blog when there is nobody that advertise on my blog?.
