When you create a Bing Ads campaign, one of the first things you have to do is set a budget. Your budget tells Bing Ads the limit you want to spend per day on your campaign. When you reach your budget, Bing Ads will stop displaying your ads until the next day.
Your budget helps keep your online advertising costs under control. By carefully selecting the correct budget amount, you spend only as much as you want to.
If you don't want to spend more than $50 per day on your Bing Ads campaign, simply set your daily budget amount to $50. Once your reach $50 in clicks, Bing Ads will stop displaying your ads until the next day.
