What Is Meta Andromeda? Why Ecommerce Brands Need Fresh Ad Creative Ready

Fourteen static ads shared a budget with established videos. By the end of the month, each static had received about 22 clicks on average. Our first read was that video had won. Looking back, the only decision we could defend was to give the statics a better test.

If you’ve heard that Meta’s Andromeda update means you need more creative, start with a different question. When you give Meta more ads, how will you know which ones actually earned a second brief?

What is Meta Andromeda, and how does it affect ad delivery?

Before someone sees an ad on Facebook or Instagram, Meta has to choose which ads are worth considering for that person. Andromeda handles that first pass. It takes a large pool of eligible ads and produces a shortlist. Later ranking models evaluate the candidates in more detail. Your ad has to enter that shortlist to have a chance of appearing. Meta’s original explanation of Andromeda.

In October 2026, Meta described an updated system that can score a larger pool of eligible ads in the same time. That helps explain why Meta can consider more creative for each person. It doesn’t tell you how many ads your brand should produce, or why a particular video received most of yesterday’s spend. Meta’s October engineering update.

We reviewed six months of creative from one booking-focused account. The data shows what happened after ads ran. We couldn’t see which ads made an individual person’s shortlist or isolate Andromeda’s effect. What we could see was where our own reading of the results needed work.

When one ad gets most of the spend, what did the others actually prove?

Go back to those 22 clicks. One additional booking from 22 clicks changes the observed click-to-booking rate by about 4.5 percentage points. That’s a thin basis for deciding what an entire creative team should stop making.

When we later gave refreshed statics a separate test, they generated 39% more bookings per click than the previous static set, at roughly the same cost per booking. Two things had changed: the creative and the way we funded it. We couldn’t credit either change alone. We could retire the claim that static ads had failed as a format.

Before the next launch, write down the decision the test should support. If you want to compare static with video, use the same offer and customer message, give both a meaningful opportunity to deliver, and decide how much a booking is worth before results come in. If the budget can’t support fourteen concepts, test fewer.

Can you forecast acquisition costs from an ad’s first month?

For videos with meaningful delivery in two months, we compared each ad’s cost per booking with the account average in the month it ran. The expensive starters went from 31% above average to about 1% above. The promising starters went from 36% below average to only 2% below. Both groups moved toward the middle.

The easy mistake was to pause a slow starter. The more tempting one was to put the strongest launch number in next month’s forecast. Across 20 ads we reviewed, those that received more spend had a median 35% increase in cost per booking. That association doesn’t establish that higher spend caused the increase. It does give a media buyer a good reason to check the spend behind a result before asking finance to count on it.

Does a stronger video hook lead to more conversions?

In one month, we compared ten videos with meaningful spend. The one with the highest completion rate had the second-highest cost per booking. The video with the lowest completion rate had the second-lowest cost. With only ten videos, we couldn’t establish a reliable relationship between viewing behavior and bookings.

We still use watch metrics when editing. If viewers leave before the demonstration, move it earlier and test the cut. When deciding whether to scale the ad, look at purchases or qualified bookings at a comparable level of spend. An editor and a media buyer can use the same report to answer different questions.

What should your next Meta creative brief look like?

Imagine a skincare brand whose highest-viewed serum video opens with a founder introducing the company. Customer reviews keep mentioning one more specific question: “Will this pill under my makeup?” That’s a second concept worth filming. Ask a creator to apply the serum, layer foundation over it, and show the finish up close. Keep the offer and destination consistent so the comparison is easier to interpret.

Write the decision into the brief: if the demo earns purchases at a sustainable CPA with enough delivery, commission a second demonstration for another customer question. If it holds attention but purchases lag, check what shoppers see after the click. If it barely spends, record the result as inconclusive. Those three outcomes call for three different next steps.

That’s where we’d put the creative budget after Andromeda: behind distinct reasons a customer might buy, with enough delivery to learn which reason earned the sale. For more on turning those questions into briefs, see our guide to UGC ads on Meta or explore Spray’s creator marketing services.
