Meta's Andromeda Update: What It Means for Ghanaian Advertisers

If your Facebook and Instagram adverts behave differently than they did two years ago, you're not imagining it. Meta rebuilt the system that decides which advert each person sees. It's called Andromeda, and it changes what works.

The short version: your creative is now your targeting.

What Andromeda is

Every time someone opens Facebook or Instagram, Meta has to pick a few adverts to show them out of millions that could run. Before the auction even happens, a retrieval system narrows that huge pool down to a shortlist for that person.

Andromeda is Meta's newer retrieval engine. Meta says it can consider far more adverts per person than the old system, and match them more personally. It was built partly because advertisers are now creating far more adverts, many of them with AI.

What changed for advertisers

Three things matter in practice.

1. Creative does the targeting

Andromeda looks closely at the adverts themselves: the visuals, the words, the format, who appears in them. It uses that to work out who each advert is for. A video of a young man unboxing sneakers in Kumasi tells Meta who to show it to more clearly than any interest you tick in Ads Manager.

That's why detailed interest targeting matters less than it used to, and broad audiences often perform well.

2. Variety matters, and look-alike ads count as one

If you upload ten adverts that are basically the same image with different headlines, Meta tends to treat them as near-duplicates. Advertisers and analysts report that very similar adverts get grouped together and compete for the same people. Ten genuinely different concepts give Meta ten different ways to find buyers.

"Different" means different at the level a person notices: a different hook, a different person, a different setting, a different format, a different reason to buy.

3. Simpler account structures win

Lots of small ad sets with narrow audiences split your budget and your data. Fewer campaigns, broader audiences and more creative inside them usually let the system learn faster.

What to do now

Make more concepts, not more copies

Plan creative around ideas, not variations. For one product, you might test:

• A problem-and-solution video ("Still buying bags that peel after a month?").
• A customer-style testimonial.
• An unboxing.
• A comparison with a cheaper alternative.
• A price and offer reveal.
• A founder talking to camera.
• A static image with a bold claim.

Each is a different door into the same product. See our creative testing framework.

Refresh often

Fresh concepts every week or two keep results from fading. Watch frequency and click-through rate for signs of fatigue. See ad fatigue.

Fix your tracking

Andromeda decides who might be interested. What Meta learns from your conversions decides who it thinks will buy. If your Pixel and Conversions API aren't sending accurate purchase data, the system can't learn what a buyer looks like. See setting up the Meta Pixel and Conversions API.

Go broader

Try broad audiences, limited only by where you deliver and sensible age ranges, and let creative do the work. Keep exclusions for existing customers when you're after new ones.

Consolidate

Fewer campaigns with more budget each. Let Meta move money between adverts inside a campaign. Meta's automated options can help here; see Advantage+ campaigns.

Why this is good news for Ghanaian businesses

The old game rewarded whoever knew the cleverest targeting tricks. The new one rewards whoever makes the most useful, varied, honest creative about their product. That's a game a small Ghanaian brand can win.

The obstacle has always been cost. If every new advert needs a photographer, a videographer, a model and a location, you can't afford ten concepts a month. That's what's changed with AI. You can now produce studio-quality video and images without a shoot, test many ideas quickly and put money behind the winners. See AI video ads in Ghana.

Common mistakes since Andromeda

• Running one or two adverts for months.
• Uploading near-identical variations and calling it testing.
• Splitting budget across many tiny ad sets.
• Judging adverts after one day.
• Ignoring tracking because "Meta does the targeting now".

Common questions

Do interests and lookalike audiences still work?

They can, but they're less important than before. Many accounts now do as well or better with broad audiences and strong creative. Test it in your own account.

How many adverts should I run?

There's no magic number. A practical starting point for most small accounts is several clearly different concepts per campaign, with a couple of versions of each. Add new ones as old ones tire.

Does this apply to Instagram too?

Yes. Andromeda selects adverts across Meta's apps, including Facebook and Instagram.
