It depends on your strategy on how you place your ads in your website if you are using google adsense program. You have more traffic but if your visitors won't see the ads, you can't make money.
I think You should make atleast 2 $ from these visitors !! Use best methods to increase adsense !! I have best trick to get good number of clicks from adsense !! I use default ads for adsense !! Therefore I have much more clicks !! Color matters a lot !! Use best color which matches like your web templates !! use at least ONe with 000ff title color.
Hey AR - I would focus on ad placement and style to start. If you place the ads in the right place and blend them into your site nicely you can increase your earnings overnight! Then beside that yeah I would work on getting more traffic. However is 200 - 400 UH if they are targeted traffic you could easily make over $10 / day minimum. Maybe even more like $20 / day or so. Depends on the keywords you are targeting on your site.
