Why did I go over my average daily budget?

Your average daily budget for your Yelp Ads campaign does not reflect the maximum you might spend on a given day. Your daily spend may go up and down on different days depending on how many people click on your ads on a given day and the cost of each click. But your total Yelp Ad spend for the month will never exceed your monthly maximum ad budget, which is calculated by multiplying your average daily budget by 30 days.
