Broad targeting is the default recommendation in nearly every Meta keynote, help article, and partner guide.
And for the top 1% of accounts, broad works flawlessly because Meta has enough historical data to predict behavior at scale.

But for many advertisers, especially those under $2k/day, with inconsistent tracking systems, or with a narrow product niche, broad fails.

This article breaks down exactly when broad doesn’t work, why, and how to fix it under Meta’s Andromeda delivery system.

The Myth: “Broad Works for Everyone”

Broad is not magic.
It’s not “smart.”
It’s not a silver bullet.

Broad only works when the algorithm has enough signal density to predict who will buy from you.

If your account lacks historical signal quality, broad feels like throwing money into a black hole.

The Real Reason Broad Fails: Missing Signal Architecture

Under Andromeda, Meta relies on:

• historical conversion clusters
• creative pattern mapping
• product-match modeling
• predicted behavior signals
• attribution density
• in-channel event reliability

Broad is not an audience.
Broad is an environment the system operates in.

And the system can only operate properly when the account has:

1. Enough conversion density
2. Reliable event quality
3. Strong creative relevance
4. Stable optimization windows
5. Consistent pixel firing
6. Cohesive account structure

No amount of “go broad” advice can overcome missing signals.

Reason #1 - You’re Not Generating Enough Signals for Broad

Broad requires velocity.

The system needs a minimum threshold of optimization events every week to create pattern stability.

If you’re below ~50 conversions/week per optimization event, broad usually fails.

Because the algorithm can’t “learn fast enough,” it defaults to random delivery.

If you see:

• Rising CPMs
• Rising CACs
• No clear delivery pattern
• Rapid cycling through pockets

→ Your signal count is too low for broad.

Solution:
Switch to a more restrictive audience for 1–2 weeks to build signal density → then go broad again.

Reason #2 - Your Creative Has No Defined Angle

Broad requires creatives that clearly tell Meta:

• who this is for
• what outcome it drives
• why they should care

If your creative is generic, diluted, or unfocused, broad delivery has no “anchor” to latch onto.

Meta isn’t choosing audiences manually.
Meta chooses audiences based on creative semantics + early behavior.

If those signals are weak, broad scatters.

Fix:
Use clear angle-driven creatives:

• Test 3–5 angles per batch
• Ensure each angle has a recognizable thematic pattern
• Refresh 2–3 times per week during heavy spend

Reason #3 - You’re Changing Too Much, Too Often

Broad thrives on stability.

If you’re changing:

• budgets
• ads
• placements
• bidding strategies
• attribution settings

…every 24–48 hours, Andromeda cannot detect meaningful patterns.

Fix:
Let broad run for at least 5–7 days with minimal interference.

Reason #4 - Your Account Structure Is Fragmented

If your account has:

• 10+ campaigns
• overlapping audiences
• inconsistent objectives
• scattered pixel events
• multiple conversion events running

→ The system is constantly forced to re-learn.

Broad punishes fragmentation more than any other audience type.

Fix:
Move toward a clean 2025 structure:

• 1 Scaling CBO
• 1 Creative Testing CBO
• 1 Retargeting BO or CBO
• Stable optimization event
• Stable attribution

Less is more.

Reason #5 - Your Conversion Event Isn’t Clean Enough

If your pixel is firing:

• duplicates
• delayed events
• out-of-order events
• missing values
• inconsistent parameters

→ Broad collapses.

Broad needs clean event hygiene to train properly.

Fix:
Audit your pixel for:

• event deduplication
• redundant GTM layers
• outdated scripts
• server-side inconsistencies
• misfiring Purchase or CompleteRegistration events

Reason #6 - Your Product Has Niche Demand

Broad works best for:

• mass-market products
• impulse-buy categories
• large TAM
• common user behaviors
• offers that appeal widely

Broad often fails for:

• narrow B2B
• complex funnels
• luxury price points
• localized services
• niche hobbies
• medically regulated products
• long contemplation cycles

If 95% of the world is not your customer, broad needs more data to find the 5%.

Fix:
Warm up with a constrained audience → then expand.

Reason #7 - Attribution Windows Are Shrinking

With shorter attribution windows (1-day click is now common), broad loses context unless the creative is extremely compelling.

Short windows = less signal.
Less signal = broad struggles.

Fix:
Ensure strong on-platform behavior signals:

• high click-through
• strong hook rate
• high watch times
• high add-to-cart volume

These help broad “fill in the gaps.”

Reason #8 - Your Creatives Fatigue Too Quickly

Broad delivers aggressively across large populations.
This means fatigue accelerates.

If you’re not refreshing at least 2–4 creatives weekly, broad slows down.

Fix:
Adopt a “creative pipeline”:

• 5–10 creatives per test batch
• 2–4 creatives per scaling refresh
• angle-driven system
• ongoing cluster testing

How to Fix Broad Fast (2025 Checklist)

If broad is not working, follow this sequence:

1. Stabilize event quality

Audit pixel + CAPI.

2. Increase signal density

Raise spend or choose a more restrictive audience temporarily.

3. Consolidate account structure

Reduce the number of campaigns.

4. Refresh creatives by angle

Introduce 3–5 distinct angle clusters.

5. Extend stability periods

Stop making daily tweaks.

6. Reintroduce broad once data stabilizes

Usually after 7–14 days.

The Truth: Broad Works - But Not Immediately

Broad is not a beginner’s strategy.

Broad is an advanced strategy that performs beautifully only when the foundation beneath it is solid.

Once your system has:

• strong creative
• consistent conversions
• stable data structures
• long-term learning
• consolidated delivery

→ Broad becomes the most efficient and scalable path.

Until then, it’s normal for broad to fail.
