How I Earned 1500 USD per month with Propeller Ads

I have a series of viral websites and they generate decent amount of traffic to be called viral. Most of my traffic comes from my social networks, SEO campaigns and a few paid strategies.

The best thing is that the traffic comprises of targeted audience. Adsense is my primary ad revenue generator, but I have always been looking for a few supplementary monetization programs.
I spent a few dollars here and there, tested a few ad programs, and it was Propeller Ads that eventually proved to be the perfect choice and did the job for us.
It is generating over $1,500 dollars a month from each site.
