What is Meta’s Andromeda Update (2025)
In late 2024 and into 2025, Meta Platforms rolled out “Andromeda”, a new ad-retrieval engine built with the NVIDIA Grace Hopper Superchip and Meta’s own MTIA hardware. It’s designed to process vast volumes of ad creatives and narrow them down to the best few thousand candidate ads for any given user. Meta reports performance uplifts: for instance, +8% in ad quality when campaigns are set up properly. Let us explore Meta Andromeda Update (2025).
What Exactly Is Meta’s Andromeda
Meta’s Andromeda update is an optimisation tool, and it is also the retrieval stage of Meta’s ad system.

Before: manual audiences, small ad sets, lots of targeting precision.
Now: a system will ask “which ad should this person see?” rather than “which person should see this ad”?
Key technical features:
- Deep neural networks custom-built to run on new hardware.
- Hierarchical indexing to manage millions of creatives.
- Emphasis shifts from audience splitting to creative variability.
How the Meta Andromeda Update Affects Your Ad Strategy
Here’s how your strategy must adapt:
1. Broad targeting, fewer splits
Andromeda works better when you aren’t over-segmenting. One campaign, broad audience, let the system optimise delivery.
2. Creative diversity becomes king
Rather than minor tweaks (headline changes or background colours), you need truly distinct ads: different hooks, formats, and personas. For example: Static image + video + carousel; testimonials + demo + lifestyle; different pain-points.
3. Simplified structure, richer assets
Less time on audience layering, more time on creative production and iteration. Structure of one campaign → one ad set → many creatives.
4. Early signals matter
With Andromeda, the system will filter under-performing creatives much faster. Focus on metrics like thumb-stop rate, early engagement, and uniqueness of creative experience.
Impact & How to Adapt Andromeda Update
Impact you’ll see:
- Better performance for campaigns that feed the system distinct, high-quality creatives.
- Lower returns if you cling to old ways: heavy audience targeting + low creative variation.
- Faster creative fatigue: because the system tests more deeply, you’ll need to refresh more often.
What to do:
- Audit your ad library: Do you have 8-15+ truly different concepts per campaign? If not, you’re behind.
- Shift budget toward creative development: allocate resources for storyboarding, multiple formats, and dynamic hooks.
- Let the algorithm breathe: don’t micro-manage placement or targeting when the objective is conversion.
- Monitor creative fatigue: watch when performance drops, and have refresh plans ready.
Risks, Pitfalls & What to Watch Out For
Pitfalls:
- Creating “variants” that are too similar: If two ads share tone, background, and creator, the system may treat them as duplicates and penalise.
- Neglecting fundamentals: A great engine won’t fix a bad offer, weak landing page, or unclear CTA. Andromeda amplifies what works, exposes what doesn’t.
- Over-reliance on automation without oversight: Even though the targeting becomes more automated, your creative strategy must be sharp and varied.
What to watch:
- How is reach distributed across creatives? Is one asset dominating? Could indicate a lack of variation.
- Rising CPA or CPC despite broad targeting could signal creative fatigue or a similarity issue.
- Refresh cadence: if your creatives are 6+ weeks old, they may already be losing signal value.
Is your ad performance stalling? If you’re observing a dominant creative, rising CPAs/CPCs, or if your assets are over six weeks old, let’s connect for a consultation to diagnose creative fatigue and build a high-impact refresh strategy.
Conclusion
The Meta Andromeda update is a system upgrade along with a major shift in how ads are selected and delivered on Meta’s platforms. For advertisers, the rulebook has changed: creative diversity, simplified structure, and trusting automation are now key. If you adapt your campaign strategy accordingly, you’ll be well-positioned. If not, your old playbook may start underperforming.

FAQs
1. Is the Andromeda update about targeting or creative?
It’s primarily about creativity. While targeting still matters, the heavy lifting moves to creative variation and letting Meta decide the best match.
2. Do I still need interest-based audiences and mic-segments?
Broad audiences perform better under this system. Use interest layers sparingly and focus more on content that speaks to different personas.
3. What’s the connection between Andromeda and Meta’s Advantage+?
Meta’s Advantage+ automates ad creation and targeting — generating tons of ad variations. Andromeda is the new AI engine that powers this system behind the scenes. It helps Meta quickly choose the right ad from all those variations for each user. In short, Advantage+ creates smarter ads, and Andromeda delivers them to the right people faster.
4. How many creatives should I prepare per campaign?
Aim for at least 8-15 distinct concepts, each with a meaningful difference (format, message, hook) rather than minor tweaks.
5. Will Andromeda fix poor ads?
Andromeda doesn’t fix poor ads; rather, it rewards strong ads and punishes weak ones faster. It will amplify your creativity, not replace it.
