So it will be really difficult for the Advertisers to pick out an option where to advertise. As the use of Social media is growing incredibly..
Seems like the Facebook system is already taking care of that problem. Facebook databases has the general user pattern activity of nearly all their users. They can boil it down to "18 y/o females living in New York City, who like the brand Prada are most likely to also like Coach". This kind of pattern is in intense algorithms. This way Facebook may post their customers' ads similar to the way Adsense does, except through the Facebook system, redirecting them back to the Facebook based fan-page.. Just a theory..
