As long as a campaign is making a profit, I keep it going, even if it is only making a 10% return, that is better than my money sitting in the bank. If I ever need to cut back on expenses, then that is when I cut down on the lowest performing campaigns. You would be suprised how fast a few low ROI campaigns can add up to total profit.
I do get good ROI like that, my best so far is ~600% I think. But I never would have gotten that if i hadent been trying out many different campaigns.
