In the campaigns table, hover over the budget amount and click the edit icon (Edit Budget). In the Edit Daily Budget modal, type the new amount or use the minus and plus buttons, which open percentage shortcuts (10%, 15%, 25% and 35%) to quickly increase or decrease it. Click Save and the change is applied right away in Google Ads. To change several campaigns at once, turn on Bulk edits, select the campaigns and use the Change Budget button in the bar at the bottom of the screen. Note: campaigns that share a budget on Google may behave differently, since the amount you edit is the budget linked to the campaign.
