There are no required inputs for Always-On Budget Optimization

Each goal can only be in one Always-On Budget Optimization Strategy.

We recommend turning on Always-On Budget optimization for ALL of your goals, even if you have a fixed budget.

If you have a flexible budget, you will get recommendations when your goals are performing below target ACoS and you have an opportunity to spend more at or below your target ACoS to generate more sales. This will ensure you aren't missing out on sales later in the day.

If you have a fixed budget, you can make decisions on potentially transitioning budgets from certain goals to the goals that are going dark prior to the end of the day. Even if you aren't able to transition budget from certain goals to other goals, it may be helpful to have visibility into which goals are doing dark, as you may want to slowly lower the ACoS targets on these goals.

As there are no inputs, the recommendations you receive for this Strategy will be the same no matter how you group your goals into strategies. You may want to separate goals if you have certain goals where you have a flexible budget and other goals where you have a fixed budget within your account.
