We all know abut the geo targeting ads, those are cool and improve convertions, but there's no real profiles and I wouldnt believe those girls were really in my town in Portugal, their nicks and descriptions are all in english.
But I see some sites using another aproach, and the profiles are real, and the girls are really in my town and speak my language, and that is awesome! I clicked a few ads myself. Look at
http://www.stickyhole.com/ and
http://www.socalmovies.com/ , there's more out there, and see what I mean. How are they doing it? I bet those pull a lot more clicks than the ones I'm using.
