I'm running Adbrite on my site www.studybabes.com (Adsense pulled their ads because they thought pictures of girls in bikinis counted as "adult content" - but Adbrite is basically the exact same thing), in 2 places: (1) in-post, between the title and body of every other post, and (2) the 300x250 square in the top right. The site gets about 250 uniques and 800 pageviews a day, 90% of which coming from referring sites. Organic traffic is very low since the site is only a month old. These ad units together only make about $1 a day. I'm thinking about adding a horizontal banner at the very top of the page, but I'm not sure yet. Any ideas?
