Hi all,
I'm going through the grind on newbie tutorial #10 and calculating my confidence intervals. The question is; when doing CPC, how often do you calculate them? Is there a rule of thumb on CPC campaigns? Say, every 100 clicks, or everytime you spend a certain multiple of the offer payout?
I know it's recommended not to do this very often as your margin of error increases, but you obviously do need to update these stats at some point to cut out ads that have no potential to get into the green.
