If your ads have felt unpredictable lately, you’re not crazy.
Costs shifting. Campaigns that used to scale suddenly stalling. Retargeting not behaving like it did six months ago.
This isn’t random.
Meta has officially entered the Andromeda era, and the way your ads are delivered, tested and scaled has fundamentally changed.
I didn’t just read the release notes. I tested it. Hard. Expensively.
Here’s what actually happened when real money hit the table.
Table of contents
First Test: 72X ROAS and I Still Didn’t Believe It
Large, well-known brand. Strong product-market fit. Solid backend.
Instead of building a complicated funnel, I leaned into high-performing organic Reels and structured the account like this:
- A broad Advantage Plus campaign letting Meta optimise
- A 30-day retargeting ad set, website visitors who viewed landing pages, added to cart or initiated checkout, excluding purchasers
- A 180-day retargeting ad set, excluding the 30-day cohort
Same creatives across all three.
The result?
The broad Advantage Plus campaign dominated.
- More than $12,200 generated in a few days.
- 22 percent conversion rate.
- 72X ROAS.
For every $1 spent, $72 came back.
I’ve worked in paid media long enough to be sceptical of “unbelievable” dashboards. This one was very real.
Key takeaways from test 1:
- Creative and broad optimisation are now doing the heavy lifting. Micro-managing audiences is losing influence.
- The traditional top, middle and bottom funnel structure still has logic, but it is no longer the primary growth lever. Automation is.
- If you’re still operating under outdated paid media assumptions, you’ll want to revisit some of the biggest myths in paid advertising and see what no longer holds up.
How you apply this
Test broad campaigns properly. Not emotionally. Not for two days. Properly.
Use creative that has already proven it can hold attention organically. If your content doesn’t convert on-site, revisit what actually makes content that converts before you blame the algorithm.
Second Test: $18K in Spend, One Clear Lesson
Different client. Large automotive brand.
This time, I consolidated campaigns and focused on creative variation.
One campaign. Three ad sets:
- Proven videos
- Proven videos plus top-performing static images
- Brand new videos for testing
Same copy. Same landing page. Maximum creative variations enabled.

After roughly $18,000 in spend:
Ad set two delivered the highest ROAS at 15.44X. $107K return of a $6.8K spend.
Sounds like the winner, right?
Not exactly.
I had to shut off all static images.
They carried the highest CPA.
The ad set looked strong at surface level, but inside it, certain creatives were bleeding efficiency while others were carrying performance.
Key takeaways from test 2:
Andromeda optimises at scale, but you still need creative-level oversight. High ROAS does not automatically equal healthy cost efficiency.
If you only look at campaign-level metrics, you’ll miss what’s actually driving profit. This is where strategic conversion rate optimisation becomes non-negotiable, because traffic quality and on-site performance now feed back into delivery learning.
How you apply this
Consolidate structure, diversify creative, but audit at the ad level. Kill what is inefficient, even if the overall ad set looks healthy.
Creative variety wins. Lazy duplication loses.
Creative Is Officially the New Targeting
Andromeda prioritises creative signals above manual audience inputs.
Your hooks, visuals and messaging now act as targeting instructions for the algorithm.
Small cosmetic tweaks are irrelevant. Entirely different angles, emotions and value propositions are what train the system.
How you apply this
Test different concepts, not different fonts.
UGC. Founder-led education. Problem-aware hooks. Offer-first messaging. Authority positioning.

Clean Data Decides Who Scales
You cannot optimise what you cannot measure.
Andromeda depends heavily on accurate optimisation signals. Pixel tracking, event configuration and attribution windows are foundational.
Bad data equals bad optimisation. Full stop.
How you apply this
Audit your tracking setup. Remove redundant events. Ensure conversion events align with actual business outcomes.
And here’s the uncomfortable truth: retention now influences acquisition.
If traffic hits your site and disappears, that behaviour feeds back into delivery optimisation. Email and SMS automation are no longer optional extras. They are performance multipliers.
If your backend systems are weak, no amount of paid traffic will save you.
The Funnel Isn’t Dead. It’s Evolving.
The old rigid funnel framework is losing control to automation and machine learning.
You’re no longer just building audiences. You’re architecting signals.
Structure clean campaigns.
Feed the machine strong creative.
Protect your data integrity.
Optimise inside ad sets, not just at surface level.
The Andromeda update isn’t something to fear.
It’s a filter.
Brands who adapt will scale. Brands who cling to outdated structures will stall.
And if you’d prefer not to learn that lesson after burning $18K yourself, you already know what to do.
