How much traffic from Ad networks can get conversions?

[viking91]

I presume that your income from one sale will be more then $1.
There is so specific way to determine that how many clicks will get you conversions but if you are using any decent ad network then the number could be high enough to make you profit.

Well approximately, I will make $10 profit from each sale so in order to make good ROI I will have to get 11 conversions from $100.
