Creative is the targeting now.
Meta's Andromeda update changed how ads find people. The algorithm reads what's inside your ad, the words, the voiceover and the visuals, and matches it to the people it thinks it fits. So the brief now does the job your audience settings used to do.
That's good news if you can make genuinely different ads and test them properly. It's bad news if your account runs on one winner and a pile of reskins.
This guide covers what changed, how many distinct concepts you need at your spend level, and how we test creative for ecommerce brands so every result explains itself.
What is Meta Andromeda?
Meta Andromeda is the system Meta uses to choose which ads, out of millions, are worth showing to each person. Instead of relying on the audience you picked, it looks at the ad itself and predicts who it's for.
It works alongside a second model that decides the order people see ads in. Every person gets their own running order of ads, with organic posts slotted in between. In practice, Meta doesn't show single ads any more. It runs sequences.
I break down what changed for ecommerce brands in this video:
What changed for advertisers
The audience did the targeting. The ad just had to convert whoever you chose.
The creative does the targeting. Different ads reach different people.
1. Targeting moved into the creative.
You used to pick an audience and load ads into it. Now you load ads, go broad, and Meta finds the people. Interest targeting and media buying hacks give very little edge.
2. Meta runs sequences, not single ads.
Andromeda matches ads to people, then the order is decided per person. A customer might see your founder story, then a testimonial, then an offer, and it's the combination that sells.
3. Audience pockets got smaller and more specific.
Two ads that say the same thing in different colours land in the same pocket. Only a real change in persona, angle or offer opens a new one.
4. Winners die faster.
The same ad shown a third or fourth time barely converts. A genuinely new ad at that point keeps the sale alive.
Our line on it: you are not making ads. You are training an algorithm.
Distinct concepts vs variations vs iterations
This is where most accounts go wrong after Andromeda. They make more ads, but not more different ads.
A distinct concept changes who you're talking to or what you're arguing. A variation changes how the same idea is packaged.
| Layer | What changes | Example | What it does |
|---|---|---|---|
| Distinct concept | Persona, angle or offer | The same supplement pitched to a new mum vs a man after a health scare | Opens a new audience pocket |
| Variation | Hook, CTA, text overlay or a minor visual | Four hooks on one body, same footage and copy | Finds out what stops the scroll |
| Iteration | A refinement of a proven winner | A winning hook rebuilt as a static ad | Extends a winner's life |
The reskin test: put two of your ads side by side. If a stranger can't say what question you were asking, you weren't asking one. A new background colour and headline on the same static is a reskin, not a test.
You need all three layers, in the right order. Variations are how you learn what works. Distinct concepts are how you reach new people. Iterations are how you keep a winner alive.
How many distinct concepts do you need?
It depends on spend. The more you spend, the faster you exhaust each pocket, and the more distinct concepts Meta needs to keep finding new buyers.
Here's what we plan for, per month:
A test unit is an ad that answers a question, not a reskin. Around 60% of the mix is static ads. Iterations sit inside these totals, and they're earned by winners, not guaranteed.
Producing that many genuinely different concepts is where UGC creators matched to each persona and AI ad creatives earn their place.
How to test creative after Andromeda
Here's the trap. When five things change between two ads, each ad lands in a different pocket. So when one gets a lower CPA, you can't tell if it was better creative or just a different group of people. You found a winner, but you can't explain it, and you can't scale what you can't explain.
That's why we test one variable at a time. It's the core of the WINMAP Method, the system behind every ad we make:
- Pick the variable. It's almost always the hook. Write 4 or 5 hooks and attach every one to the same body, footage, copy, CTA and format.
- Give it enough spend to mean something. Three hooks tested properly beat eight tested badly. If the budget can't separate a real difference from noise, run fewer variants.
- Write down what won and why. One line per test: the variable, the winner, the number. This is the step that compounds.
- Only then multiply. Build new bodies, statics, creators and formats around the proven hook. This is where the distinct concepts come from, and they're what open new pockets.
One variable keeps the read clean. The multiply step feeds Meta the variety Andromeda rewards. You need both.
How we structure the account
- Broad targeting. Let the creative do the targeting.
- One concept per ad set, so the learnings stay readable. At lower spend, consolidate to one ad set per persona with the angles inside it, so conversion data pools. At higher spend, split to one ad set per angle.
- A spread of awareness stages. 1 to 3 genuinely different concepts per stage, from people who've never heard of the problem to people ready to buy.
- Never pull a winner out and relaunch it. Launch fresh ad sets of the same concept alongside it.
- Validate ideas organically first where you can, before putting paid spend behind them.
Keep or kill: the Sequence Read
Because Meta runs sequences, an ad with a poor ROAS can still be doing a vital job. So we never judge an ad on ROAS alone.
Put frequency and ROAS side by side at ad level, on your cold campaigns, over the last 30 to 60 days:
| Frequency | ROAS | What it is | What to do |
|---|---|---|---|
| Low | Low | Top-of-funnel fuel | Keep, if the campaign is on target |
| High | High | Bottom-of-funnel finisher | Keep, but don't pour budget on it |
| High | Low | Dead | Kill it |
| Low (with real spend) | High | A genuine winner | Scale it |
I walk through exactly how to read this in your own account here:
Diagnose at ad level, decide at campaign level. Use 7-day click attribution with existing customers excluded. CPA is the headline number; hook rate is a diagnostic, not the verdict.
Benchmarks we use
- Frequency: a weekly account frequency around 2 is healthy. Cold ads above 2 are fatiguing.
- The scaling signal: when frequency climbs towards 3 to 4, stop adding budget and make more top-of-funnel creative instead.
- The One-Variable Audit: look at your last 10 tests and count how many changed only one thing. Most accounts we audit score 1 or 2 out of 10. Under 3 out of 10 means you're not running a testing programme, you're guessing.
8 common mistakes after Andromeda
- Counting reskins as tests. New colours and headlines on the same ad land in the same pocket and teach you nothing.
- Testing hooks with different bodies underneath. If hook two wins, you don't know if it was the hook or the edit.
- Calling it too early. Killing an ad on day two with £40 and eleven clicks is reacting to noise.
- Scaling a winner without writing down why it won. When it fatigues, you start from zero.
- Killing the low-ROAS ad. It's often the top-of-funnel ad feeding your winner, and the winner slides a week later.
- Pouring budget on the high-ROAS finisher. Spend goes up, frequency goes up, returns stay flat.
- Letting one ad eat all the budget. It means Meta has no fresh top-of-funnel creative to work with.
- Blaming CPMs. Usually your CPMs aren't rising. You're showing the same people the same ad.
What this looks like in a real account
When All Real Nutrition came to us, the account leaned on static ads and there was no creative testing system. Nothing was tested in a structured way, so there was no way to know which ads were working or why.
We installed single-variable testing, launched 120+ creatives, and wrote down why each winner won. In 4 months, at the same spend, CPA fell 58% and new customers grew 50%.

What is Meta Andromeda?
Meta Andromeda is the system Meta uses to pick which ads to show each person. It reads the content of the ad, the words, voiceover and visuals, and matches it to the people it predicts it fits, rather than relying on the audience you selected.
Does interest targeting still work after Andromeda?
It gives very little edge now. Broad targeting with genuinely different creative usually performs better, because the creative tells Meta who the ad is for.
How many ads do I need for Meta Andromeda?
It depends on spend. As a guide, around 6 distinct concepts a month at $3k to $15k of monthly spend, rising to 36+ at $150k+. Distinct means a new persona, angle or offer, not a new colour or headline.
What's the difference between a creative variation and a new concept?
A new concept changes who you're talking to or what you're arguing, and opens a new audience pocket. A variation changes the packaging, like the hook or CTA, and tells you what stops the scroll.
How do I know when an ad is fatigued?
Watch frequency. Cold ads above a frequency of 2 are fatiguing, and when it climbs towards 3 to 4, adding budget stops working. That's the moment to launch new top-of-funnel creative.
