If you mean a pay per click affiliate program, then I need to introduce you some resources where you get paid based on pay per click action. In fact, there are some revenue sharing programs which enable you put some ads on your web pages and pay commissions whenever someone clicks on the ads. Google Adsense is the number one program in this field. Adbrite is another example. Bidvertiser is the third one. Well, i hope it will help. Good luck!
I am trying to look for some that have quality close to Google adsense. Perhaps a good payout is nice.
I have done alright with Chitika. They are sort of like a product network where they show product details on your site from banner ads and they then pay per click. How much they pay I am not sure, but they do pay per click as I have received one check from them so far. Also, it is not my site. It is a site that I earn from.
