I read clydes post about a year ago of how he lost 2,400 of his MFA sites. I'm just thinking if each of those made $1 dollar per day (and they probably made more), then that's a lot of money.. A lot of people apparently do this on a smaller scale, but I've never heard of it until now. I understand it's a website that's geared towards ranking with adsense, but where is the money made? Do you need a CPA, are they tiny tiny niche stores, or are they just content sites with ads on them? See, I get the idea of what they are, but I don't understand how money is made with them.
