buzincarl, Depends on site. Really, I don't low about the lowest, but not more than $35 and it's very very optimistic. In your sig I see proxies...well then, one more of a million you will earn not much
contents to draw traffic with proper placement of ads will increase your earning, however, how much you can earn per day? is hard to know. Experiment with the keywords you use and then keep using high paying keywords.
I suggest that you make more content rich websites. this is the key to making the amount you want. There is no short cut to it. If you want to make it with just one site, it wuill take you a lot of time and effort which is better distributed on other websites that you will make.
Content websites are the way to go. Build a HUGE content site! SEO as much as you can! and $100 is not very far...
