Meta’s Andromeda Update Explained (2026): Why Your Ads Crashed and How to Adapt

Andromeda is the biggest change to how Facebook delivers ads in years. It’s an AI overhaul, and it quietly raised the bar for who gets to scale. If your ads suddenly crashed or your CPMs jumped, this is probably why. The advertisers who adapt to it are thriving. The ones still running ads the old way are getting quietly cut out.

Meta rolled Andromeda out at the end of August 2025. Most advertisers only felt it in Q4.

Performance shifted. Old strategies died. Costs climbed for no obvious reason.

It’s still the framework that decides what works on Meta in 2026. Here’s what actually changed under the hood, and exactly how to adapt.

What the Andromeda update actually is

Andromeda is Meta leaning much harder on AI across the advertising side. How it reads your creatives. How it distributes budget. How it judges your business.

Underneath all the technical changes sits one clear intent. Meta wants advertisers to behave like established brands. Professional creative, real marketing strategy, and genuinely happy customers.

The update is built to cut out advertisers who don’t operate at that level. Adapt, and you get rewarded with cheap, stable delivery. Don’t, and your performance erodes over time.

There are four shifts that matter. The first two are about how you run ads. The last two are the ones almost nobody talks about, and they’re about your customer experience. They tie straight into your feedback score.

Change 1: every ad needs a different concept, not variations

This is the change that breaks the most accounts.

The old playbook was simple. Take one winning ad, then test 80% variations by swapping the hook, the voiceover, the B-roll. That no longer works. Andromeda’s AI recognizes when you’re just re-uploading the same ad with a new hook, and it penalizes you for it.

What Meta wants now is genuinely different concepts. Aim for around 20 brand-new concepts per week.

Think problem-solution ads, founder-story ads, UGC, street interviews, product-testing and how-to, “10 reasons this beats the competitor,” and so on. The more distinct concepts you keep in your portfolio, the more Meta spreads budget across them. And the more stable your performance stays.

Change 2: fewer, broader campaigns, and let Meta decide

Cramming 40 to 50 near-identical ads into one campaign to “test variations” is over. Here’s the structure that’s working across the accounts we manage.

• Fewer campaigns. One per objective, broad targeting, with at least 10 different creatives and enough budget in each.
• A CBO testing campaign you pour lots of distinct concepts into. Let Meta decide what to spend on. Don’t force spend like the old days.
• A CBO scaling campaign where you move the concepts that proved themselves, at higher budgets.

One tip that matters. Meta will sometimes over-optimize toward people who already bought from you. You’ll notice lots of returning customers but few new ones. Exclude your existing customer list on testing and scaling campaigns, so Meta optimizes toward fresh acquisition instead of quietly retargeting your buyers.

Change 3: customer feedback is now a much stronger auction signal

This is the side of Andromeda almost no one talks about.

Alongside the creative and structure changes, Meta quietly increased how much customer satisfaction weighs in the ad auction. In our experience, from around October your customer feedback became a far stronger signal driving campaign performance. Meta never communicated this clearly. And the visible page score has been glitched or hidden for over a year, which led plenty of advertisers to wrongly assume feedback stopped mattering.

It fits the whole philosophy behind Andromeda. If Meta is raising the standard for who gets to advertise, a huge part of that is making sure those businesses actually make customers happy. Here’s what Meta effectively rewards now.

• Be accurate. Creatives have to represent what you actually sell. Especially clothing, sizing, and results claims. Overpromising gets penalized.
• Clear delivery and returns. Make your shipping and return policy easy to find and easy to understand. Meta’s AI reads your website and can penalize you before a single customer complains.
• Provide tracking. It cuts the “I never received it” and “no response” complaints that are a huge red flag when the feedback survey hits.
• Step up customer service. Fast replies to DMs, email and comments. Honor returns and exchanges. Set clear reply-time expectations, and an auto-reply works. Tell customers about delays or out-of-stock items before they get angry, not after.
• Don’t outrun your inventory. Scaling too fast, say jumping past $5 to 10k a day within a couple of months, can be a red flag on its own. Meta may check your feedback signals before letting you scale further.

And it goes beyond post-purchase surveys. Those in-feed prompts, the “Do you like seeing ads like this? Was the website experience good?” ones, feed the same system. Unclear policies, unrealistic claims, and pushy tactics like fake countdowns or fake low-stock warnings can be penalized directly by Meta’s AI. No customer complaint required.

Change 4: turn on Facebook page reviews

Andromeda also pulled Facebook page reviews and recommendations into the mix. These are the responses to Facebook asking users whether they recommend your page, rolled into a rating from 0 to 100%. The higher that recommendation score, the better your ad performance.

So make sure reviews are turned on, and actively work the score up. It pairs with your customer feedback. Lifting one without the other has limited effect, so push both together.

What to do: the Andromeda adaptation checklist

The through-line is simple. Meta is filtering for businesses that look and behave like real brands. Professional creative and a genuinely good customer experience. Everything Andromeda rewards points back to that.

Why Andromeda made your feedback score the thing to fix

Here’s the strategic takeaway. Andromeda didn’t just change creative strategy. It turned customer experience into a core auction lever.

Your feedback score and page reputation now sit upstream of your CPMs and your delivery. So if your ads crashed this cycle and your creative is genuinely diverse, the problem is almost always on the customer-experience side. The exact signals behind your feedback score. That’s usually the highest-leverage thing you can fix.
