Depends on : 1. Your CTR 2. CPC for the keywords Assuming you have 10% CTR and $1 CPC, you can earn $20 per day.
It depends on how much Google pays you for click. Adds related to some hot keywords pays up to $1.5 per click, but for most of the keywords you will get paid something around $0.05. Do the math.
Various factors are involved in figuring the net revenue so add the codes to find how much you make a month.
With 200 uniques/day I'd try CPA rather than Adsense. Of course it depends on what your blog is about - it may not be suitable for CPA at all. But in general, it's not easy to make money with Adsense.
With that new of a blog, I bet those 200 visitors are not actual visitors but spammers, bots, etc. Pennies if anything I'd say.
If your blog is keyword rich and has very good content, on the initial month you will earn around 30$, you need to improve the site traffic to earn more and also concentrate on keyword rich contents.
