Meta ads for ecommerce: Advantage+ sales campaigns and Andromeda
This page is about the technology and how to judge it. For the channel decision as a whole, read our paid media strategy for ecommerce.
What does it do?
Three things sit behind the word "Meta ads".
Advantage+ sales campaigns (formerly Advantage+ shopping campaigns). Meta's developer blog says the shopping version uses machine learning to automate audience, creative, budget, optimisation and destination1. That is what Advantage+ sales campaigns means in practice: fewer decisions are yours. In 2025 Meta's developer blog said advertisers would no longer have to choose between an Advantage+ shopping campaign and a manual one, with both in a single setup rolled out first to selected advertisers3.
Andromeda. Meta Andromeda is Meta's engineering name for the retrieval stage of ad recommendation. It narrows tens of millions of candidate ads to a few thousand, which larger ranking models then sort2. It is not a campaign setting. You feed it ads and it decides which ones get considered.
The account itself. Campaigns, ad sets and ads still exist. See the Meta Ads Manager account structure for where Advantage+ settings sit.
One more piece: the Meta learning phase, the period in which Meta's delivery system learns who to show an ad set to, and when.
Why do e-commerce brands use it?
Because the people are there and the catalogue maps to the ads. Our view: for a shop with a product feed and decent creative, Meta is usually the second channel to take seriously after search.
Automation also removes setup work. Fewer audiences to build. Fewer knobs to turn. That is the pitch, and for some accounts it holds.
How do we implement it?
Check purchase events
Meta can only learn from the events it receives. Clean purchase tracking comes before scaling.
Set the structure
Decide what Advantage+ may cover and what stays in manual campaigns. Plan changes in batches.
Plan the creative
Someone keeps producing new ads and watching for creative fatigue, because the ads carry more of the work.
Decide how to judge it
Agree in advance how you will judge Meta outside its own panel. If spend is large, plan a proper test.
When should you not use it?
Do not scale it if purchase tracking is broken. Fix that first.
Do not hand it the whole budget if you cannot see what it did. Our view: a campaign type you cannot question is a risk, not a plan.
Do not judge it by Meta's own dashboard alone. If the spend is large, plan a proper test.
What does it cost in effort?
No figures. The effort is:
- Creative. Our view: with audience choice automated, the ads themselves carry more of the work. Someone has to keep producing new ones and watching creative fatigue: a drop in results after people have seen an ad too often.
- Tracking. Meta can only learn from the events it receives. Clean purchase events come first.
- Structure. Decide what Advantage+ may cover and what stays in manual campaigns. The trade-offs are in Advantage+ vs manual campaigns.
- Measurement. Decide in advance how you will judge Meta outside its own panel. Meta incremental attribution is one option inside the platform: it optimises delivery for conversions Meta's model predicts the ads caused. It is still Meta's model.
- Reading. Someone has to question the reports, not only copy them.
Pitfalls
Advertising to people who already bought
A Meta-ads commentator said on his podcast that Advantage+ shopping campaigns gave no way to exclude people who bought the promoted product5. That matters for products people buy once. Check what your account allows today.
Changing controls
Meta's developer blog said the Existing Customer Budget Cap would be deprecated in the API together with the old Advantage+ shopping campaign API3. If your set-up relied on it, check what replaced it.
Reading platform ROAS as profit
It credits ads, not margin. See ROAS before you set a target.
Too many edits
Our view: constant tweaks make it hard to tell what changed the result. Plan changes in batches.
Believing explanations of Andromeda
Marketing blogs often turn it into creative rules. Our view: unless Meta says it, treat it as a guess.
Our take: Core
In our view, Meta is Core. That is our rating, not a market fact.
Our reasoning: Meta documents both Advantage+ sales campaigns1 and Andromeda2 in its own engineering and developer posts, so most shops will meet them either way. "Core" does not mean "trust the dashboard". Meta's own developer post includes results it claims for Advantage+ shopping campaigns1. Treat those as Meta's claims, not as your expected outcome.
A 2023 trade-press headline framed the choice as a dilemma: results or control4. Our view: that is the right question. Automation can work. You still need a way to check whether it worked for you.
Our view: A Meta report is not a lift test. It tells you what Meta credits. It does not tell you what would have sold anyway.
FAQ
What are Advantage+ sales campaigns?
Meta's automated campaign type for sales. Meta introduced the shopping version as automated ecommerce advertising1. It was previously called Advantage+ shopping campaigns.
What is Meta Andromeda?
Meta's engineers describe it as the retrieval stage of ad recommendation: it picks the candidate ads that a later ranking stage sorts2. It is not a setting you can switch on.
What is the Meta learning phase?
The period in which Meta's delivery system learns who to show an ad set to, and when. Our view: judge an ad set after that period, not during it. The full definition is in the Meta learning phase entry.
Is Advantage+ better than manual campaigns?
It depends on your account. Trade press has framed the choice as results versus control4. The way to know is a test on your own data.
Does Meta tell me what was incremental?
Not through its standard report. That shows credited conversions. Incrementality needs a comparison with people who did not see the ads.
Do I need to build audiences first?
Less than before, because Advantage+ sales campaigns automate audience choice1. Creative and purchase tracking matter more.
