Your bid will go higher on searches that are more likely to convert and lower on searches less likely to convert. Over the long haul or at the end of the month, though, we will try to make sure that your average CPC is not higher than your bid.

In the unlikely event that your campaign's spend goes over your monthly limit, Microsoft Advertising will refund the overspend at the end of the month.
