Budget bid strategy includes campaigns that use a shared budget

Although a budget bid strategy can't adjust the budgets of Google Ads and Microsoft Advertising campaigns that use a shared budget, the strategy does set bids for campaigns in shared budgets. However, for budget bid strategies with auction-time bidding enabled, Google Ads campaigns can be in shared budgets. Search Ads 360 automatically creates shared budgets and puts campaigns in them.

For budget bid strategies without auction-time bidding enabled, the budget bid strategy will only optimize the daily budgets of the campaigns that aren't using an engine's shared budget. For budget bid strategies with auction-time bidding enabled, the budget bid strategy will optimize the daily budgets.

Auction-time bidding for budget bid strategies is available as a preview for customers who have agreed to be early testers and reviewers. If your agency or advertiser would like to test this feature, contact your Search Ads 360 account manager.
