Advantage+ is the starting point now, not an option, so the paid-media job shifts from configuring campaigns to governing an automation you no longer fully steer.
A director opens Meta Ads Manager to launch a campaign and finds the machine already holding the wheel. The audience, the placements, the budget split, and the creative treatment come pre-selected. Nothing was announced in the room. The defaults simply flipped, and control left by inertia.
The Day the Defaults Flipped
The incumbent way put the marketer in charge of structure. You chose the audience, set the placements, split the budget, and the platform executed. Reporting that cites Meta's own Advantage+ help page states that as of February 2026, every new campaign starts with Meta's AI in charge of who sees your ads, where they appear, and how your money is split, launching with Advantage+ Audience, Advantage+ Placements, creative enhancements, and campaign budget optimization all pre-selected (The Memo).
This is secondary reporting; Meta's own Advantage+ help page could not be fetched in this research session, so the exact Meta wording should be re-verified before you rely on it in a board setting (The Memo). The direction is clear regardless. The default is now automation, and manual is the exception you have to choose.
What Meta Now Controls By Itself
Read what "default on" transfers. Three decisions move from the marketer to Meta: who sees the ad, where it runs, and how the budget is spent. A vendor setup walkthrough confirms Advantage+ Placements is on by default at the ad-set level, which is one more control leaving the operator's hands by default (AdNabu). That is a commercially biased source, so weight it as confirmation of the default, not as a benchmark (AdNabu).
Then read the tell. Reporting states that in March 2026 Meta added a control to cap spend on existing customers (The Memo). Meta shipped that control because broad automation over-spends on people who already buy. The platform conceded the failure mode in the form of a knob.
The 22% ROAS Claim, Read Skeptically
Meta has a number for this. A Danish practitioner write-up states Meta reports roughly 22% higher return on ad spend for Advantage+ versus manually set-up campaigns, while stressing this is Meta's own benchmark and independent advertisers' results vary widely (Manids Marketing).
Attribute that 22% to Meta, because Meta is grading its own automation. A vendor-reported lift from the vendor that profits when you cede control is a marketing claim, not an independent benchmark. It may be directionally real. It is not board-grade evidence, and a director who repeats it as neutral fact is doing Meta's copywriting.
Creative and Signal Are Your Last Levers
When structure automates, the levers that remain are the ones the machine cannot set for you: the ad creative and the first-party conversion data you feed back. Creative quality decides what the automation has to work with. Clean conversion signal decides whether the automation optimizes toward real revenue or toward noise.
The operator edge moved. It is no longer campaign structure. It is creative volume and signal quality.
The Fork You Now Face
You have two ways to run Meta now. Accept the defaults, let the automation own who, where, and how much, and call the platform's 22% your result. Or govern the automation: audit every new campaign for silently-on settings, set the existing-customer budget cap deliberately, and reinvest the freed setup time into creative volume and server-side conversion quality.
That is not campaign management. That is oversight of a system you rent.
Automation you do not audit is a budget you do not control. A ROAS claim you do not question is a vendor's headline. A creative pipeline you do not fund is a machine running on weak inputs.
Govern the automation, do not trust it. The machine will decide who, where, and how much unless you decide first. Keep the two levers it cannot pull for you, and treat every default as a setting to review, not a recommendation to accept.
