Set a budget for your campaign
Google Ads uses daily budgets—if you’re working with a monthly budget, just divide that figure by 30.4 (the average number of days in a month). Google Ads aims to show your ads until your daily budget is met, and you pay only when someone clicks your ad. Learn more about charges and your daily budget
