Your Facebook ad playbook isn’t outdated. It’s wrong. Meta’s Andromeda system completed its global rollout in October 2025 and changed the fundamental rules of how paid social works.
TL;DR
Meta’s Andromeda system replaced Facebook’s entire ad delivery infrastructure in October 2025. Creative signals now determine who sees your ads, not your audience settings. Campaigns following the new playbook (1-3 core campaigns, 10-15 distinct creative assets, Advantage+ enabled) report 20-35% higher ROAS. If you’re still running the old structure, you’re leaving money on the table. [1,2]
I’ve been running paid social campaigns for over a decade. I’ve seen algorithm updates, iOS changes, creative trends come and go. Most of the time, “the algorithm changed” is an excuse marketers use when their creative isn’t good enough. Andromeda is different. This isn’t an update to how Meta ranks ads within an audience. It’s a complete replacement of the underlying infrastructure that has powered Facebook advertising since the beginning. [1]
If your Meta ROAS has dropped in the last six months and you can’t figure out why, Andromeda is almost certainly part of the explanation.
Andromeda is powered by NVIDIA GH200 Grace Hopper Superchips and optimizes at the individual user level rather than the audience level. [3] That last part is the critical distinction.
The old system worked like this: you defined an audience (women aged 25-44 interested in yoga in the UK), and Meta served your ad to that audience. The algorithm optimized which people within your defined audience were most likely to convert.
Andromeda works differently. Meta scans its entire user base and retrieves matches based on the signals in your creative: the visual content, the copy, the emotional tone, the product category, the implied context. Your audience settings become a boundary condition, not the primary targeting mechanism. [1,2]
This is why advertisers who haven’t changed their campaign structure are seeing unexpected performance shifts. The system they optimized for no longer exists.
Here’s the thing that took me a while to fully accept: audience targeting matters less. Creative matters more. [2]
When Andromeda scans your creative to determine who should see it, every element of that creative becomes a targeting signal. The person in the ad, the setting, the product use case, the emotional register, the first three seconds of a video. These signals tell Andromeda who this ad is for, and it finds those people across its user base more accurately than most manually-defined audiences.
The practical implication: the strategy of running five variations of the same creative with different headlines or color schemes doesn’t feed the retrieval engine useful signals. You need conceptually distinct creative: different scenarios, different people, different emotional hooks, different use cases for the same product. Each asset teaches Andromeda something different about who your customer is.
The old structure that many accounts still run: 10+ campaigns, each targeting a different audience segment, with 2-3 ad sets per campaign and a handful of creatives. This made sense when you controlled the targeting. It doesn’t make sense now.
The new structure recommended by performance marketers who’ve adapted to Andromeda: [1,4]
Advertisers following these practices report 20-35% higher ROAS compared to those still running legacy structures. [2] Meta’s own data shows a 22% ROAS lift when advertisers turn on Advantage+ features. [3]
The “10-15 conceptually distinct assets” instruction is where most advertisers get stuck. What does “conceptually distinct” actually mean in practice?
It means different scenarios, not different colors. Here’s an example for a B2B SaaS product:
Each of those is conceptually distinct. Andromeda’s retrieval engine can extract meaningfully different signals from each one and use them to find different segments of your potential audience.
On copy: the first line still matters enormously. Andromeda may scan creative signals, but the hook that stops the scroll is still human psychology. Test bold claims, specific numbers, direct questions, and surprising contrasts. What’s changed is the volume of creative you need to be testing, not the fundamentals of what makes good copy.

Let me be straight about the frustrating parts, because not everyone is seeing the 22% lift.
Marketing Brew reported in April 2026 that some advertisers are finding Meta’s AI creative features turning back on after being disabled, spawning new creative assets that the advertiser didn’t approve, and overriding decisions that had already been made. [5] That’s a real problem, especially for brands with strict creative guidelines or regulated industries.
The “less targeting, more creative” approach also requires more creative production. If your team was already stretched on content output, being asked to produce 10-15 distinct concepts per campaign is a significant ask. The system works brilliantly if you have the creative volume. It’s less forgiving if you don’t.
And honestly: some verticals haven’t seen the gains. The 22% lift is an average across a vast range of advertisers and categories. Your mileage will vary based on your product, your audience, your margins, and how quickly your team can adapt its creative process.
These are the concrete changes worth making right now:
What is Meta Andromeda?
Meta Andromeda is a complete replacement of Facebook’s ad delivery infrastructure. Powered by NVIDIA GH200 chips, it optimizes at the individual user level using your creative signals, not your audience settings, to determine who sees your ads.
How does Andromeda change Facebook ad targeting?
Previously, advertisers defined audiences and Meta served ads to them. With Andromeda, Meta scans its entire user base and matches ads to users based on the signals in your creative. Audience settings are now boundaries, not the primary targeting mechanism.
How many creatives should I run per campaign in 2026?
Experts recommend 10 to 15 conceptually distinct creative assets per Advantage+ campaign. These should be genuinely different scenarios and concepts, not color or copy variations of the same idea.
Has Andromeda actually improved ad results?
Results vary. Advertisers following the new best practices report 20-35% higher ROAS. Meta’s official data shows a 22% ROAS lift with Advantage+ enabled. However, some advertisers report unwanted AI creative generation and feature override issues.
Should I still use custom audiences on Facebook in 2026?
Yes, for retargeting warm audiences (website visitors, email list, past purchasers) and exclusions. For cold prospecting campaigns, Andromeda typically outperforms narrow interest-based or lookalike targeting. Creative quality matters more than audience definition for new customers.
