My first day was 0 I think lol. But, since then iv done my research, and i'll never be at that low again! *hopefully* lol
When I first started, AdSense wouldn't accept me so I settled for AdBrite. First day was like 10 cents with them. Then I redesigned my site with AdSense in mind, and ran it for about 2 weeks w/o ads. When I got accepted into Google, my first day was like 3.xx. I was real happy and it has been going up since.
first day, first week, first month = $0 2nd month was ok 3rd month i was satisifed 4th month i was shocked
