Updated for the Andromeda era of Meta Ads (2025)

Scaling Meta ads isn’t supposed to feel random - but for many advertisers, performance becomes unpredictable the moment they try to increase spend. One day your ROAS is stable, the next day everything collapses. If you’ve ever wondered why Meta ads stop scaling even when the product is strong, you’re not alone.

This guide breaks down the most common reasons scaling stalls in 2025, based on public Meta guidance, independent testing, and patterns commonly seen across performance accounts.

1. You’re Not Feeding Meta Enough Creative Volume

With the rollout of Meta’s Andromeda updates, the platform now relies more heavily on automation to match creative → audience → intent.

Meta’s public recommendation has been consistent:

Use more creative variations, not fewer.
Give the system more options to find incremental pockets of performance.

Low creative volume (e.g., 2–3 ads) limits the system’s ability to adapt as spend rises. This becomes especially obvious when increasing budgets - Meta simply runs out of fresh combinations.

What to do instead:

• Aim for 10+ creatives per ad set (hooks, formats, aspect ratios).
• Refresh creatives weekly for higher-spend accounts.
• Introduce variety: UGC, product demos, testimonials, and static ads.

When creative volume increases, scaling becomes more stable because Meta has more “paths” to spend efficiently.

2. Your Audience Selection Is Too Narrow (or Too Broad)

In the Andromeda era, Meta does a better job at exploring audiences automatically. But this doesn’t mean every brand should rely only on broad targeting.

A common scaling blocker:

• Only running broad when your account needs additional signals.
• Only running interest stack tests when the audience pool is too small.

Both extremes cause scaling issues.

When broad works:

• High creative variety
• Conversion-rich accounts
• Strong site/LTV data
• Wider product-market fit

When broad struggles:

• Small audience signal
• Niche product
• Weak creative diversity
• Low daily spend

The most scalable approach today:

Run a portfolio of audiences, not just one.
This includes:

• Broad
• Interest clusters
• Lookalikes
• Historical winners (when refreshed)

This mirrors how Meta explores audiences automatically - you’re simply giving it more structured options.

3. You’re Scaling Budgets Faster Than the System Can Stabilize

One of the most common scaling mistakes is increasing budget too aggressively.

Examples:

• Jumping from $50/day → $200/day overnight
• Scaling multiple ad sets at the same time
• Introducing new creatives while scaling

When this happens, Meta resets portions of learning and has to re-stabilize performance. During that period:

• CPMs rise
• CPCs increase
• ROAS drops
• Delivery becomes uneven

What to do instead:

• Scale 20–30% increments on strong performers
• Use horizontal scaling (additional ad sets) alongside vertical scaling
• Protect scaling on days where performance is already volatile (seasonality, competition spikes)

Slow + steady almost always outperforms aggressive scaling.

4. You’re Keeping Fatigued Audiences Running Too Long

This is one of the least understood scaling blockers.

Even if an audience was a “winner,” it will eventually hit a temporary saturation stage. During scaling, this shows up as:

• Stable CPMs → suddenly rising
• Strong ROAS → suddenly dipping
• Spend → suddenly volatile
• A consistent ad set → becomes inconsistent overnight

This is known as the audience fatigue or saturation effect.

The solution isn’t to abandon the audience - it’s to rest it.

Most audiences rebound if you:

• Pause them for 1–3 weeks
• Reintroduce them with new creative
• Rotate them as part of a broader audience portfolio

Scaling requires a steady rotation of fresh audiences, not just fresh creatives.

5. Your Account Doesn’t Have Enough “Signals” for Scaling

Meta’s ads system optimizes based on signals - especially purchase or app event signals.

If your account has:

• Low volume
• Inconsistent purchase patterns
• Narrow windows of activity
• Small daily budgets

Then scaling becomes hard because Meta doesn’t have enough reliable conversion patterns.

How to fix signal issues:

• Consolidate campaigns
• Use fewer ad sets with larger budgets
• Improve landing page conversion
• Use Advantage+ Shopping when applicable
• Feed Meta more events (add-to-cart, view content, etc.)

The more signals Meta sees, the more confidently it scales spend.

6. You’re Scaling Without Strong Foundational Metrics

Marketers often scale based on short-term metrics (e.g., yesterday’s ROAS).
But scaling requires trend-based metrics, not snapshots.

You want to see:

• 2–3 consecutive “win” days
• Stable CPMs
• Strong audience engagement
• Consistent conversion rate
• No early signs of creative fatigue

Scaling is safer only when the trendline is positive.

7. You’re Relying on Guesswork Instead of Consistent Analysis

Most scaling failures come from uncertainty about:

• Which audiences are improving
• Which audiences are fatiguing
• Which audiences to rotate next
• How long winners typically last
• When performance is truly declining vs temporarily unstable

You can’t scale Meta ads effectively if you’re guessing.

A data-driven, trend-oriented approach — whether manual or tool-assisted — makes scaling more predictable, especially during volatile periods.

Key Takeaways

Scaling Meta ads in 2025 requires:

• Higher creative variety (aligned with Meta’s Andromeda guidance)
• A portfolio of audiences instead of a single broad ad set
• Gradual budget scaling, not aggressive jumps
• Rotation of fatigued audiences
• Strong foundational signals
• Trend-focused metrics instead of daily snapshots

Most advertisers don’t struggle because Meta is “inconsistent.”
They struggle because scaling magnifies issues that were already there — creative gaps, narrow audiences, limited signals, or inconsistent decision frameworks.

When those are addressed, scaling becomes far more stable and predictable.
