CPA Explosion
CPA is a system that has the potential to pay you significantly more money than conventional campaigns. While with PPC you might be making $0.30 per click, with CPA you can make as much as $40 per action. You can drive less traffic, have fewer hits on your website, and still make MUCH more money.
CPA is an easy and innovative way to capitalize on whatever traffic you are getting, even if it's just a few dozen hits a day.
