Meta Andromeda, explained for premium and luxury brands
Andromeda is the AI that decides which of your ads each person could see. Here's what it is, what changed in 2026, and how luxury brands should adapt their creative, structure and measurement, in plain English.
Your creative is now your targeting.
Every time someone opens Instagram or Facebook, Meta has millions of ads it could show them. Andromeda is the first filter: it reads every ad and every person and shortlists the few thousand ads most likely to be relevant. Only ads that make that shortlist go on to be ranked and bid on.
Because Andromeda judges the ad itself, not just the audience you picked, the creative you upload now does most of the targeting. Different ads reach different people. Near-identical ads compete for the same people.
Meta's ad retrieval AI
The system that narrows tens of millions of possible ads to a shortlist for each person, in milliseconds.
The ad finds the audience
Detailed interest targeting matters less. The content of each ad tells Meta who it's for.
Variety beats volume
Ten tweaks of one ad act like one ad. Genuinely different concepts open up new pockets of customers.
Simplify, diversify, refresh
Fewer campaigns, broader audiences, more distinct concepts, and a steady pipeline of new creative.
Three stages, in the blink of an eye
Andromeda is one part of a bigger system. Think of it as the casting call that decides which ads even get an audition.
Retrieval: Andromeda
Scans every eligible ad and shortlists the few thousand most likely to suit this person right now. If your ad doesn't make the shortlist, it can't be shown.
Ranking: GEM and Lattice
Meta's large ranking models score the shortlist, predicting who is likely to click, watch or buy. GEM is Meta's ads foundation model; Lattice consolidates many smaller models into fewer, larger ones.
Auction
The top-ranked ads compete on bid and predicted value, and the winner is shown. Better creative wins more auctions for less.
What Meta has said about Andromeda, and when
The figures below are Meta's own reported numbers from its engineering posts and earnings updates. They're platform-wide averages, not promises for any single account.
What Andromeda does and doesn't mean
There's a lot of noise about Andromeda. Meta hasn't published creative quotas, similarity scores or a magic number of ads, so treat anyone who quotes one with caution.
“More ads always means more reach”
Uploading 50 near-identical variations doesn't help. Similar ads are treated alike and compete for the same people. Distinct concepts are what widen reach.
“Targeting is dead”
Audiences still matter for exclusions, geography and Advantage+ suggestions. They just matter less than the ad. The creative now does most of the finding.
“Luxury brands should go lo-fi”
Variety doesn't mean cheap. A luxury mix can include creator and founder content, but every piece should still look and sound like the house.
“A strong hook is enough”
Stopping the scroll is the minimum. Meta learns from what people do next: watch time, clicks and purchases decide which ads keep winning.
Six ways premium brands should use Andromeda
The goal is simple: give Meta enough genuinely different, on-brand creative to find every type of buyer, without diluting what makes the brand premium.
Build concepts, not tweaks
A new background or headline isn't a new ad. A new idea is: craft, heritage, the product in use, a customer's story, a founder's point of view. Start with three to five distinct concepts, then vary within them.
Mix formats and voices, keep the standard
Studio film, editorial stills, creator content, founder-to-camera and product close-ups each reach different people. Hold them together with consistent type, colour, tone and finish.
Simplify your account
Fewer campaigns and ad sets with broad audiences give Andromeda more room and more data. Use Advantage+ campaigns where they fit, with exclusions and brand safety in place.
Feed the system steadily
Add new concepts on a regular rhythm, roughly every two to four weeks depending on spend, rather than one big drop a season. Retire fatigued ads instead of letting them drag.
Stay in control of the brand
Meta's generative creative tools can change your images, text and music. Review each enhancement before switching it on, and keep anything that alters the product or the house look off.
Measure beyond ROAS
Judge creative on hook and hold rate, then on new customers, blended MER and full-price revenue. Platform ROAS alone can reward ads that sell to people who would have bought anyway.
Six concepts every luxury account should have live
Each concept speaks to a different reason to buy, so Andromeda can match it to a different type of customer. Make two or three executions of each in different formats.
Eight questions to ask of your Meta account this month
Do we have three or more truly different concepts live?
If every ad would be described the same way, Meta sees them that way too.
Is our structure as simple as it can be?
Consolidate overlapping campaigns and ad sets so each gets enough data to learn.
Are our audiences broad enough?
Let the creative find people, and use exclusions to protect existing customers and brand.
When did we last add a new idea?
If it's been more than a month, performance is probably running on fatigued ads.
Do we have video, stills and creator content?
Different formats reach different people across Reels, Stories and Feed.
Have we reviewed AI creative enhancements?
Switch on what helps, switch off anything that changes the product or the look.
Are we tracking hook and hold rates?
They tell you why an ad works, not just whether it did.
Do we report on new customers and blended MER?
So growth is real, not just retargeting people who were buying anyway.
More on Meta from The Journal
Andromeda is Meta's AI system for ad retrieval. For every person, it narrows tens of millions of possible ads down to a shortlist of a few thousand, which are then ranked and auctioned. Meta introduced it in December 2024 and upgraded it significantly in October 2026.
No. There is no Andromeda setting in Ads Manager. It runs behind every Meta campaign. What you control is the creative, structure and signals you give it.
Meta hasn't published a number. What matters is how different the ads are. For most premium brands, three to six distinct concepts, each with a few executions across formats, refreshed every few weeks, is a sensible starting point.
Not cheap UGC. Creator and customer content can add a valuable new angle, but it should be briefed and shot to the brand's standard and sit alongside campaign and studio work.
Usually yes, as the core of a simplified structure, because they give Andromeda the most room to match creative to people. Keep exclusions, placements and creative enhancements under review to protect the brand.
Meta says Andromeda now evaluates over a billion ads per second, around 100 times the 2024 version, using a more advanced model and faster hardware, and reports a 2.4% lift in Facebook conversions since 2025. The advice for advertisers is unchanged: give it distinct, high-quality creative.
