I saw last thread on daily earning. It is very interesting! But without information on visitors, it is hardly to make a case and find some useful information. Plus, the daily earning flunctuates so much. It makes more sense to calculate the ratio of monthly earnings per visitors. I just started adsense ca ten days ago and got earning so far as $23 per 3500 visitors that is 0.65 per 100 visitors. So is this good or bad? what is your number?
