On a more serious note, i'm making about $25 per day with a CTR of 0.07%. Getting about 50,000 steady impressions now.
PER DAY ??????????? AND YOU ONLY MAKE $25 PER DAY???? THAT IS TOO LOW !!!! WOW!!! how many websites do you have?
I'm currently at 29 sites, no niche and targetted at webmasters... $25 is good to be honest lol http://cl.ly/2oro - so far today (sideways ftw)
Varies dramatically by day of the week, time of day, and lots of other stuff I never quite managed to put my finger on. I get anything from $2 to $30 a day. Edit: apparently I average 10k impressions a day, and 8.5k UV a day. Not all of those see the ads though I'd imagine, since I have 16k page views a day.
YAY yesterday I got $3.. $2 more and I can buy me a subway! now I never make a $0. And IM VERY happy about that!
