Just found this in my AdSense control panel 🙂
PPA – Pay Per Action.
If you’ve been working with COPEAC or similar system you probably know how this works.
If not – I can describe in few words.
1. You place Google Ad code on your website.
2. When Visitor clicks on it you don’t get an revenue.
3. If Visitor make a lead (registration action or buy something) you’ll get the revenue.
Revenues are quite big in comparison with AdSense PPC system.
I just started testing it and will provide you with results soon.
Keep in touch.
