Meta has quietly changed the rules of the game.

If your ad performance tanked in the last couple of months higher CPMs, fewer conversions, and zero new “winning” creatives, you’re not alone.

Welcome to Meta Andromeda, the new ad delivery system that’s transforming how ads are ranked, tested, and scaled.

TL;DR:

Meta’s new Andromeda ad algorithm update 2025 is revolutionizing how ads are ranked and delivered. The new AI-driven creative optimization system rewards ad diversity and penalizes repetitive formats. If your Facebook advertising performance declined recently, it’s not your targeting; it’s your creative strategy. To scale, marketers must feed the system with fresh, diverse creatives, adopt stealth-style formats, and leverage tools like Vibemyad to automate creative remixing and testing.

What Exactly Is Meta Andromeda?

Meta’s Andromeda update is an AI-powered ad delivery architecture built to make Facebook and Instagram smarter, faster, and more predictive. Unlike the old flat model that relied on user engagement history, the new hierarchical AI system uses multi-layered neural ranking to test, optimize, and serve ads dynamically, in real time.

Here’s how it works:

User Requests: Every time a user opens Facebook or Instagram, Meta receives billions of engagement signals.

Ads Corpus: These signals are matched with a vast pool of potential ads.

Hierarchical Ad Index: The system quickly narrows down relevant ad clusters.

Hierarchical Model: Different AI models predict which creative will perform best for that user in that moment.

Ad Candidates: The top-scoring ads are shown, and the process repeats in real time.

This all runs on Meta’s MTIA and NVIDIA Grace Hopper GPUs, making it incredibly fast but also more selective.

Why Your Ads Are Struggling Now

If your Meta ad performance dropped to higher CPMs, fewer conversions, and slower learning, Andromeda is the reason. The algorithm now prioritizes creative freshness and ad diversity. Repetitive or recycled UGC-style ads signal low novelty, leading to poor delivery.

Because the new system prioritizes creative diversity and engagement freshness, your old “winner” ads may be getting deprioritized.

In short:

• Meta’s AI now favors breadth over repetition.
• Too few creatives = low data variety = poor learning signals.
• Recycled UGC formats (the same talking-head style) trigger user fatigue, reducing your ad’s ranking in the new hierarchy.

Simply put:Meta’s AI now favors creative variety over repetition. If your ad account feels like it’s being throttled, this is why.

How to Fix It: Structure Your Ad Account for Andromeda

1. 15–50 Creatives per Ad Set

Group by angle (problem, desire, emotion) instead of concept.Example: If your concept is “eco-friendly fashion,” test angles like affordable luxury, celebrity-approved, sustainability for moms, etc.

2. Let the Budget Flow

Stop micro-managing spending. Let Meta’s system allocate budget automatically to the best-performing creatives.

3. 10–20 New Concepts Monthly

Meta rewards fresh inputs. The more unique ad signals it receives, the better it predicts conversions.

4. CBOs for Angles or Personas

Run Campaign Budget Optimization (CBO) around specific angles or personas, rather than focusing solely on a single product line.

With CBO, you set one campaign-level budget, and Meta dynamically distributes it across your ad sets based on performance. The system prioritizes the ad sets and creatives that drive the best results, saving you time and maximizing ROI.

5. Persona-Specific Landing Pages

Align your ads and LPs (landing pages) for each target audience to maximize relevance.

6. Creative Strategy Map

Maintain a tracker of what works angles, tones, hooks, and formats, and update it weekly.

What’s Actually Working: Stealth Creatives

Stealth creatives are ad formats that don’t look like ads. They mimic real social interactions, building trust and authentic engagement that Meta’s new algorithm now rewards.

Winning Stealth Formats:

• Podcast-style clips
• Skit-style conversations
• Mock reviews between friends
• Reaction videos on trending memes

They blend into social media feeds through natural dialogue, storytelling, and subtle selling.

Why They Work

Conversational Tone - Two characters talk like real people, not sales reps. - Builds trust and removes the “I’m being sold to” feeling.

Authority + Relatability - One person educates, the other represents the audience’s doubts. - Keeps the ad informative yet personal.

Strategic Selling Blocks - Storylines move naturally from curiosity - problem - solution - proof.

Many brands struggle under Meta’s Andromeda update because repetitive creatives and untested formats no longer get the engagement they used to. Ads may be shown less frequently, audiences may tune out, or conversions may drop unexpectedly.

• Creative Remixing: Refresh your existing campaigns by auto-generating new hooks, tones, and variations in minutes.
• AI-Driven Insights: Identify which audience personas and creative angles resonate best to boost relevance and conversions.
• Stealth-Style Templates: Use trending ad formats that blend naturally into feeds, increasing engagement without feeling like traditional ads.
• Real-Time Creative Analytics: Track which creatives Meta’s AI favors, so you can double down on what works and stop wasting spend on what doesn’t.
