Hi I got an old domain that I used to sell thing on. I've never sold anything on this domain and never done any CEO with it. But I'm on first page in google with a couple of keywords and have around 25-30 daily visitors. Do I have the posibility to earn a lot of money on this site if I start doing SEO and get 100 people a day (its in norway, so its not so many people here ) or do I need more than that to start earning on adsense. What I'm asking is, what is 100 visitors a day worth in google adsense?
