Don't know since I abhor them...I can tell you that they do cause "not good earnings per click" on sites they advertise on.
MFA with duplicate content especially do not earn a lot at all. If you have a site that is made for adsense but with quality unique content.. and if its marketed well can earn decent money..
Well as far my information MFA site does not have much earning from Google Adsense because of rare content on website.
I would think that they must make some sort of money, otherwise people wouldn't bother setting them up. Don't know how much though.
The main reason for setting them up is laziness I think. People not willing to invest the time in actually creating decent, unique, useful content. People with $-signs in their eyes who got taken in by the latest "guru" and think they are going to get rich by slapping up some POJ site and sitting back and going through the Ferrari catalog.
I believe that it depens on niche. If you choose mortgage or health niche, walla, you're on your way.. : )
It's not like all those myspace layout, arcade, directory and proxy sites are actually unique or useful. Plus, MFA pays pretty well.
The days of MFAs are gone.. Google has become wiser since then. MFAs used to earn a hell lot of money in the initial days, but now the only earnings potential about MFA are through Reseeling of MFA site lol.... All the "1000 MFAS sites with unique content" sales pitch from spammers to unwitting rookies on the online earners world.. But then most of the websites today are MFAs only... You research a few keywords, build a website around that, create unique content(no necesarrily original), try to rank well for those keywords, and bingo you have an MFA albiet unique and non-spammy but MFA nontheless. Thats what we all do... Evolution of MFA... When people proclaim that they hate MFA sites, they are just expressing their hatred for automated MFA sites.. Manual MFAs are Okay it seems .. How else would you explain trying to rank better than a genuine informative site with a good SEOd site on the same topic..
i dont have idea but i know that big sites are in alexa top 100 . image that how much they earn but i think they earn so much from cheating from us: mad:
$3000 per month does not include maintenance and promotion. I guess that they'll only make $1000 per month.
