How Does Ad Scheduling Work?
Ad scheduling lets you set times of the day and days of the week when you want to show your ads. It runs weekly, which means you cannot set weeks of the month or months of the year. You can use it to prevent your ads from showing completely outside of the times you set. If you want to make them appear outside of these times, you can still apply bid adjustments to increase your bids during your chosen times automatically.
In addition, ad schedules apply to all of your ad groups within your campaign. It means you are not allowed to set ad scheduling at the ad group level. However, if you really have to, you can get around this with custom rules. If you’re having a hard time figuring this out, you can seek help from Google Ads specialists.
