What Is Advantage+ Campaign Budget in Meta Ads?

With Advantage+ campaign budget you hand Meta a single campaign-level amount and let it decide how much each ad set gets. The amount can be daily or lifetime. Meta’s help centre says the feature was formerly known as campaign budget optimization, and it also calls it “campaign budget” or “budget with Advantage+ on”. Because spend follows opportunity, judge results at the campaign level, not ad set by ad set.

How does Advantage+ campaign budget decide where money goes?

Meta distributes the campaign budget continuously, in real time, to the ad sets it sees as having the best opportunities, and spends less on underperforming ones. It does not aim for an equal split. With 2 active ad sets, Meta says it might spend most of the budget on one of them if that gets the best overall result. For that reason Meta advises analysing results at the campaign level. Meta also says the feature is best suited to campaigns with at least 2 ad sets; a campaign with one ad set works the same as an ad set budget.

Is your campaign eligible?

Meta lists these requirements for every ad set in the campaign:

Requirement	What must match
Budget type	All ad sets use the same type, lifetime or daily
Bid strategy	All ad sets use the same strategy: highest volume, bid cap or cost per result goal
Optimization event	All ad sets share it, when the bid strategy is highest volume
Delivery type	Standard delivery on all ad sets

Sales, leads and app promotion campaigns have Advantage+ campaign budget turned on by default. A campaign can hold more than 70 ad sets, up to 200, but Meta limits the edits you can make after publishing at that size.

How do you turn it on?

1. Turn on the Advantage+ campaign budget toggle when you create the campaign.
2. Choose whether the campaign budget is daily or lifetime.
3. Enter the budget amount.
4. Choose a campaign bid strategy.
5. Set a schedule inside each ad set if you use a lifetime budget and want ads to run on a schedule.
6. Click Next, pick your start date under Budget & schedule, and finish the ad set settings.

Meta enforces a 2-hour minimum between switching the feature on and off. If you need it off sooner, Meta suggests pausing the campaign and creating a new one with ad set budgets.

Can you still control spend on one ad set?

Yes, with ad set spend limits, set as a percentage or an amount. A maximum spend limit caps an ad set over a Sunday-to-Saturday week at 7 times the limit, so a single day can run higher. A minimum spend limit is a target, not a guarantee, and Meta issues no refunds for missing it. Meta recommends using as few limits as possible and not setting both a minimum and a maximum on the same ad set. If you switch from campaign budget to ad set budgets, your spend limits reset.

When are ad set budgets the better fit?

Meta points to ad set budgets when you need to control the amount each ad set spends, when ad sets differ greatly in value or audience size, or when ad sets use mixed optimization goals or bid strategies. A middle option, ad set budget sharing, keeps your own ad set budgets but lets Meta move up to 20% of the daily budget between ad sets.

FAQ

Is Advantage+ campaign budget the same as CBO?

Yes, if by CBO you mean campaign budget optimization. Meta’s help article on lifetime budgets describes Meta Advantage+ campaign budget as “formerly known as campaign budget optimization”. Meta’s other budget articles also call it “campaign budget” or “budget with Advantage+ on”.

Why is one ad set getting almost all the budget?

That is how the feature is designed. Meta moves the campaign budget toward the ad sets with the best opportunities and may spend most of it on one ad set. If you need a floor or ceiling for a specific ad set, add a minimum or maximum ad set spend limit.

Can I turn Advantage+ campaign budget off right after turning it on?

Not straight away. Meta requires at least 2 hours between switching it on and off. If you turned it on less than 2 hours ago and need ad set budgets now, Meta suggests pausing that campaign and creating a new one that uses ad set budgets.
