Nice post Stephen, thank you!
I'll study more deeply these 2 programs ( Google Adsense & Yahoo! Publisher ) because they may fit on some of the sites I'm building.
Still, atm I'd have some questions: Do you have affiliate sites where your you mix PPC publishers ( ex. Google Adsense & Yahoo! Publisher ) and PPS ( pay-per-sale ) merchants?
And what's most important, how do these 2 types of programs return income ?
Hope I didn't ask any stupid questions, but I consider the "only stupid questions being those that remain unasked"
