I have some decent traffic from all over for one site of mine. Demographics are distributed and selling products is not working. Adsense is not an option. I need your advice on how I can monetize this traffic. What are the best "pay per impression" programs out there? I could think only till that. Sometimes the traffic comes in hordes from Digg etc. but they are there only to read on page/post and go off. How do you monetize Digg kind of traffic? Pl. do advice.
