After creating a new Sales, Lead Generation, or App Promotion campaign, you'll choose your budget strategy, either at the Campaign or Ad Group level.

  • Full automation: To automatically optimize your budget allocation across ad groups, choose the Automatic campaign budget (CBO) option. Enter your campaign budget as needed and choose between daily or lifetime budget. Note: When you set a budget at the campaign level, you must have the same optimization location, goal, and event, and target CPA across all ad groups.

  • Minimal automation: For more manual control, select the Custom ad group budgets option, which lets you choose different budget and bidding settings for each ad group.
