When does Adsense starts racking in dough of about atleast $20 a week or so or approximately $100 a month? What is the general number of unique visitors a day does one need to reach. What numbers were you at when you reached this point (no. of visitors, no. pf articles, etc.)? Just a few questions I thought I should ask.
There are to many variables to make any assumptions with visitors/articles/etc. You can have 30 visitors on one site and make just as much as 500 on another. Then you can have three articles on one site but have a generic domain name and have three articles on another domain but really crappy and not indexed properly. I would say the average before getting $100/month would probably have to be at around ~3000 uniques. Just a guess.
Like Fka said, there is no set number of visitors or articles and such. I started getting around $100/month with about 1000 impressions per day...(stupid low paying keywords)
