Ok my site is new the first day i made 9dollars (not what i made but im just using it as a perpestive)...The next day i made 10, then 19... today i had 9000 unique visits (due to digg)... and i only make $9? today i had 15x more traffic then any other day and i make 1/20th the amount of money? Why is this??...Wow are they cheating me?
First up, the $9 day isn't that unusual as it's Sunday in the US I think? You'll find there're less clickthroughs on weekends, and the $9 is in line with your previous earnings. Next up, Digg visitors are EXTREMELY ad blind and almost never click on ads. You'll have to monetize traffic that in other ways
Maybe, you have been smart priced because your clicks are not converting for the advertisers. However, it may be too early to confirm it is smartpricing.
That depends on a lot of things. What niche are you in? What keywords are you targetting? How are your ads layed out? Where is your traffic coming from (besides digg)? Etc
