True or false? Your campaign should be limited by its budget setting when you want to limit losses on unprofitable campaigns that are being optimized.

True. Setting a budget limit is a crucial control mechanism for unprofitable campaigns undergoing optimization. It prevents excessive spending on strategies that are not yet yielding positive returns. Without a budget cap, an underperforming campaign could deplete resources rapidly, leading to significant financial losses while you are still experimenting with improvements. This allows for controlled testing and iteration without risking the entire marketing budget.
