An affiliate nerwork told me: "You bid for traffic and the highest bidder gets the greater volume of traffic." Ok...so more money i spend, more views i'll receive. But if they suggest a bid from 0,03$ to 1$, why spend 1$ when you can spend 0,03$ and receive 1000 views? I can't understand this... Of course, if i spend 1$ probably my ads will show for example more times in a day (i believe), instead if i bid 0,03$ probably i'll get something like 100 views in a month... Isn't?
