Maybe you can request adsense robots in your site. then, make some advertisement adjustments. With that much visitors, you should be aerning atleast $15/month if you know what you are doing.

If your page views are good.. You can go for Adbrite..!
They page for page views too!

That's very low earning. I got about 300 visitors a day. And i earned average 10-15$ a day. Can you tell me which niche you are in.........

yeap, got to agree.... mine still earning less than 50cts per day... I hope to learn and earn to increase traffic and target audience visitors to $5 per day perhap within a year
