Then you have to factor in whether or not any of those blogs has substantial traffic.
If you have 100 blogs with 200 hits on them daily, then it's going to be difficult to make money with that 20,000 hits.

If you had one blog with 20,000 unique visitors then YES you can make nice money with that. All spread out though...it's harder to get a sale off a few hits. Sites just don't convert like they used to thanks to the fact that everything is now free. So it's tough.
