What Meta says Advantage+ does
Meta's pitch for Advantage+ is straightforward: hand the algorithm a URL, a creative asset, and a budget, and it handles targeting, placement, bidding, and optimisation automatically. No audience segments to build. No A/B test structures to manage. The system learns and improves as it runs.
The headline numbers Meta publishes are good. Brands restructuring campaigns to maximise Advantage+ chat signal integration are reporting an average 18% improvement in ROAS. Advertisers consolidating fragmented campaign structures into Advantage+ report up to 32% reduction in cost per acquisition.
What agency leads are actually saying
Marketing Brew published practitioner interviews this week that put the numbers in a different light. Three agency perspectives worth reading carefully:
Hawke Media's SVP of services said Advantage+ now accounts for 60–70% of the agency's Meta spend, but said the tools have a habit of steering ads toward low-quality placements. The attribution metrics are directionally useful, not precise. And a full account structure hasn't been replaced — the agency is still running manual campaigns alongside Advantage+ to maintain control.
A media director at Deutsch described the experience of clients being opted into new AI features without notice — having to "play Whac-A-Mole" to identify what Meta had turned on in the background. She said she's encouraged clients to test Advantage+ creative tools but hasn't found a single brand willing to hand creative decisions to the AI. The reason: brands invest heavily in their visual identity and aren't comfortable with automated creative modifications.
Growth marketing agency We Scale Startups reported seeing performance gains from Meta's non-creative automation tools — audience optimisation and budget allocation — but consistently worse results from Meta's AI creative tools compared to their own AI-generated creative with specific brand guardrails. Their teams now produce AI creative externally with detailed brand guidelines and feed it into Advantage+ rather than using Meta's in-platform generation.
⚡ The pattern
Advantage+ audience and budget automation: generally works. Advantage+ creative generation: underperforms against human-directed AI creative for brands with established visual identity. The automation layer that matters is the one you feed with strong inputs.
Why the ROAS numbers need context
The 18% ROAS improvement figure from Meta comes with a caveat buried in the data: it reflects early adopters — brands with strong tracking infrastructure, high creative volume, and well-structured existing campaigns. These are not brands that turned on Advantage+ and waited. They built the conditions that make the algorithm work.
A study from Measured found that Google's comparable product, Performance Max, had incrementality rates consistently lower than what the in-platform attribution suggested. The concern with Advantage+ is identical: the system is optimised to deliver the conversion, not to prove it was incremental. It gravitates toward users who were already likely to convert — existing customers, warm retargeting audiences, people deep in the funnel — because they're the easiest win.
That inflates ROAS in Meta's reporting. It doesn't necessarily inflate actual business outcomes. An apparel brand test found only 17% of reported Advantage+ conversions were truly incremental.
Where Advantage+ genuinely works
The real practitioners — not Meta's case studies — are converging on specific use cases where Advantage+ earns its place:
- E-commerce at meaningful scale. Accounts spending above $10K/month with catalogues of 20+ products see real gains. Below that threshold, the algorithm doesn't have enough conversion data and manual campaigns outperform.
- Scaling proven creative. Advantage+ excels when you have a creative combination that already works and you want to find more buyers. It's a scaling engine, not a discovery tool.
- Audience and budget optimisation on all campaign types. Even advertisers who won't touch Advantage+ creative report value from automated audience expansion and budget allocation.
- High-traffic event periods. Black Friday, product launches, seasonal sales — Advantage+ can react to market signals faster than manual optimisation during compressed timeframes.
Where to be cautious
Three specific situations where practitioners are pulling back:
- Brand-sensitive creative. Advantage+ creative modifications can go off-brand without warning. As of March 2026, Meta has added a persistent opt-out for creative automation, but you have to set it. Check your Ads Manager.
- B2B and complex funnel campaigns. Advantage+ is optimised for purchase signals. It performs worse for lead generation with long sales cycles, where conversion intent is harder to read from behavioural data alone.
- Accounts without solid first-party data infrastructure. Advantage+ amplifies good inputs and bad inputs equally. Without a properly configured Conversions API feeding clean first-party signals, you're giving the algorithm less to work with than its headline performance implies.
The shift this creates for marketing teams
The strategic question for paid social is changing. When Advantage+ handles audience selection, bidding, and placement optimisation, the lever you control is creative strategy and data quality. The agency that wins isn't the one that builds the most intricate audience segments. It's the one that feeds the algorithm the strongest, most diverse creative assets and the cleanest conversion signal.
That's a significant skills shift. Media buying expertise — the craft of building layered audience structures, optimising bids by segment, testing placement splits — is being absorbed into the platform. Creative direction and data architecture are becoming the differentiators.
This is uncomfortable for teams that built their value proposition around campaign management. It's an opportunity for teams that were already focused on creative strategy and measurement infrastructure. The marketers who get ahead of this reframe won't need to rebuild their approach when Advantage+ becomes even more dominant. They're already practising it.
