I am more curious to know how much traffic it takes for a site like this to become profitable ads? Anybody has any details? ps: I guess quite a few of us have such "Oh that would be a fun site" ideas... I just don't know what traffic will make it worth the effort.
My rent is $1050 / month, I live with two friends. Adsense pays me per click, but when I charge advertisers, I charge them CPM.
August - 150k uniques
Sept. - 100k uniques
Nov. - 140k uniques
organic = ~20%
referral = ~30%
direct = ~50%
I don't get direct advertisers often, but when I do, I charge them anywhere from $2 - $5 CPM (obviously it depends on the company)
Edit: I forgot to mention, the AMA title was "I run ThatHigh and it pays my rent in SF" so I guess it's safe to say that he makes at least $1050/mo from the site.
