name	meta-ads-optimizer
description	Optimize running Meta Ads campaigns — audience refinement, budget scaling, learning phase management, placement optimization, automation rules, and creative rotation coordination.

Process

1. Diagnose — Identify the specific performance issue (rising CPA, declining ROAS, learning phase stuck, placement inefficiency, etc.)
2. Check tracking first — Most Meta performance issues trace back to signal quality. Verify CAPI, EMQ, event deduplication before optimizing bids/audiences
3. Analyze root cause — Use the Diagnostic Decision Tree
4. Select optimization lever — Match problem to framework
5. Implement changes — Respect learning phase (don't touch ad sets <7 days old or with recent edits)
6. Monitor for 5-7 days minimum — Meta needs time to stabilize after changes
7. Iterate — Small, incremental adjustments

Diagnostic Decision Tree

Symptom	Most Likely Cause	Start Here
ROAS declining over 2-4 weeks	Creative fatigue (most common)	Creative Rotation → use meta-ads-creative-engine skill
CPA rising, frequency >4	Confirmed creative fatigue	Creative Rotation
CPA rising, frequency normal	CPM inflation or competition	Budget/Bid Optimization → review CPM trend
Ad sets stuck in Learning Limited	Too many small ad sets OR weak signals	Learning Phase Management
Delivery dropping suddenly	Check disapprovals, Special Ad Category flags, payment issues	Account Health Check
Conversions dropped but clicks stable	Tracking issue — Pixel/CAPI problem	Use meta-ads-tracking-setup skill
ASC underperforming	Weak tracking, insufficient creative, or ratio wrong	ASC Optimization
Great CPA but can't scale	Audience saturation or budget jumps too aggressive	Scaling Playbook
Retargeting CPA worse than prospecting	Audience too small (<1K) or fatigued	Audience Refinement

Learning Phase Management

Meta's most critical optimization principle: keep ad sets OUT of learning phase as much as possible. Meta research: advertisers with <20% of spend in learning see up to 68% lower CPA.

Learning Phase Rules

Rule	Detail
Duration	5-7 days minimum (50 events needed to exit)
What resets learning	Budget change >20%, audience change, creative swap, bid/optimization change, attribution window change
What doesn't reset	Adding new ads (without removing old), small budget changes (<20%), pausing within ad set
Goal	<20% of total spend in learning phase
Event volume needed	50+ conversions/week per ad set to exit learning optimally. 25+ minimum for stability

Fixing "Learning Limited" Status

Cause	Fix
Budget too low for optimization event	Increase budget OR optimize for higher-funnel event (e.g., switch Purchase → AddToCart if <25 purchases/week)
Audience too narrow	Expand audience (broader lookalikes, remove restrictive filters)
Too many ad sets competing	Consolidate ad sets with overlapping audiences
Weak Pixel/CAPI signals	Fix tracking first — use meta-ads-tracking-setup skill
Creative failing to attract conversions	Test new creative (use meta-ads-creative-engine skill)

Consolidation rule of thumb: If you have 5+ ad sets stuck in Learning Limited, consolidate to 2-3 larger ad sets with pooled budget. The algorithm prefers fewer, larger ad sets with sufficient event volume.

Audience Optimization

Audience Refresh Triggers

Trigger	Action
Frequency >4 at creative level for 7+ days	Audience fatigue — expand audience or refresh creative
CPA rising with stable creative	Audience saturation — expand lookalikes or add broader audience
Retargeting audience <1,000 users	Too small — expand recency window or consolidate with cold
CRM list >60 days old	Refresh customer match list
Custom audience not growing	Check event pixel firing; audiences capture from creation date forward

Expansion Tactics

Current State	Expansion Move
1% lookalike saturated	Test 2-3% lookalike
3% lookalike saturated	Test 5-10% or broad targeting
Narrow interest targeting	Remove interests, test Advantage+ audience
Country-specific lookalike	Expand to new countries with localized creative

2025 best practice: Accounts with strong Pixel + CAPI signals typically find that broader audiences outperform narrower ones. The algorithm does the targeting work — your job is providing creative that converts.

Exclusion Maintenance

Post-March 2025: Detailed targeting exclusions removed. Use customer list exclusions instead.

Exclusion	Apply To	Refresh Cadence
Past purchasers (all time)	Prospecting campaigns	Monthly
Recent purchasers (30 days)	Retargeting campaigns	Monthly
Active subscribers	Prospecting	Monthly
Engaged leads in pipeline	Prospecting	Weekly

Budget Scaling Playbook

Vertical Scaling (increase budget on winners)

Action	Rule
Budget increase	20% maximum per change
Frequency	No more than once per 3 days
Requirement	Ad set in Active status (not Learning), CPA at or below target for 3+ consecutive days
Monitor	Watch for efficiency decay after each increase
If efficiency drops	Hold for 7 days before next increase, or roll back

Why 20%? Larger jumps can reset the learning phase or destabilize delivery by shifting the algorithm's pacing too quickly.

Horizontal Scaling (duplicate or expand)

Action	When
Duplicate winning ad set with new audience	Current ad set saturated (rising frequency)
Launch new lookalike tier (1% → 2% → 5%)	Need new audience pool
Launch in new geographies	Validated product-market fit in existing markets
Add new creative variants	Fatigue detected (frequency >4)

CPM Context (Critical 2025 Factor)

Meta's average ad price rose 9% in 2025 (Meta Q1 2025 earnings). When diagnosing rising CPA, always check if CPM inflation is a contributing factor — it may be partial cause of efficiency decline, not creative or audience failure.

Placement Optimization

Advantage+ Placements (Default)

Let Meta distribute across all eligible placements. Recommended default unless:

• You have creative only in certain specs (e.g., only 1:1 square — missing 4:5 Feed and 9:16 Reels)
• You have strict brand safety requirements
• You've verified via placement breakdown that specific placements consistently underperform

Manual Placement Review

Check placement-level performance monthly:

Placement	Watch For	Fix
Facebook Feed	Strong baseline — primary performance	Ensure 4:5 vertical creative
Instagram Feed	Strong for younger audiences	Ensure 4:5 vertical creative
Instagram Stories	Ephemeral, high engagement	9:16 full vertical, captions mandatory
Reels	Fastest-growing, mobile-first	9:16, attention-grabbing hooks
Audience Network	Clicks but low quality?	Exclude if conversion quality poor
Messenger	Specific use cases	Only include with messaging objective
Right Column	Lower CTR but cheap CPM	Include for remarketing

Decision rule: Exclude a placement if its CPA is >2x account average for 30+ days with sufficient volume (100+ clicks).

Automation Rules

Set up rules in Meta Ads Manager OR use third-party tools (Birch — formerly Revealbot, Madgicx).

Core Automation Rules

Rule	Trigger	Action
Pause underperformers	CPA > 2x target for 3 days AND 100+ clicks	Pause ad
Budget scale winners	CPA < 70% of target for 3 days AND in Active status	Increase budget 15%
Frequency control	Frequency > 5 at creative level	Pause creative (or notify)
Low-quality placement exclusion	Placement CPA > 3x account avg for 7 days	Exclude placement
Budget reallocation	Ad set A CPA < B CPA by 30%+	Shift 20% of B's budget to A
Creative refresh alert	CTR drops 20% below 7-day average	Notify team to add new creative

Best practices:

• Start with notification-only rules before auto-actions
• Set conservative thresholds first — tighten over time
• Always require minimum volume (100+ clicks, 10+ conversions) before rules trigger
• Exclude learning phase ad sets from optimization rules

ASC Optimization

Advantage+ Shopping Campaigns have limited manual levers. Optimize these:

Lever	How
Creative quality and volume	Add new creatives weekly. Maintain 15-30 active creatives (max 150 per campaign)
Customer ratio (new vs existing)	Test 70/30, 80/20, 90/10 splits based on your actual new customer acquisition needs
Catalog quality	Keep product feed fresh and complete — ASC uses catalog for dynamic product ads
Budget sufficiency	Need 100+ conversions/week for ASC to work well. If volume insufficient, switch to manual campaigns
Pixel + CAPI strength	ASC relies entirely on signal quality. EMQ below 6.0 = ASC underperforms

When to ditch ASC: If ASC underperforms manual campaigns after 30 days with strong creative and tracking, the account may not have sufficient conversion volume or signal quality for ASC to work. Fall back to manual 3-campaign structure (Prospecting + Retargeting + Testing).

Example

Input: "I run an ecommerce store on Meta. Spending $12K/month. ROAS was 4.5x last month, now 2.8x. Frequency on my top ad set is 5.2. Using ASC. What should I do?"

Output:

Meta Ads Optimization Plan

Current Performance Summary

Metric	Current	Target	Gap
ROAS	2.8x	4.5x	-38%
Frequency	5.2	<4.0	+30% over threshold
CPA	(implied rising)	Historical	Needs calculation
Learning phase spend %	Unknown	<20%	Needs check

Root Cause Diagnosis

Creative fatigue is the primary driver. Frequency at 5.2 is well past Meta's fatigue threshold (>4). Meta's own research: 45% conversion rate drop at 4+ exposures. Your ROAS decline (-38%) is consistent with severe fatigue.

Secondary factor: Meta's average CPM rose 9% in 2025, contributing some background cost pressure.

Optimization Actions

Priority	Action	Lever	ICE Score	Timeline
1	Refresh ASC creative: add 6-10 new creative variants, pause highest-frequency creatives	Creative	10×9×8 = 720	Day 1-3
2	Verify CAPI + EMQ (ASC depends on signal quality)	Tracking	9×8×8 = 576	Day 1
3	Check customer ratio setting — if 50/50, test 80/20 (new/existing) to push more acquisition	ASC config	7×7×9 = 441	Day 2
4	Add fatigue automation rule: pause creatives at frequency 5+	Automation	7×8×8 = 448	Week 1
5	Mix formats — if ASC is heavy on static images, add video/Reels-native content	Creative	7×7×6 = 294	Week 1-2

Creative Refresh Plan

Use the meta-ads-creative-engine skill for systematic creative testing. Immediate priorities:

1. Pause 3 highest-frequency creatives today
2. Add 6 new variants across formats: 2 static, 2 video (15-30 sec, 9:16 vertical), 2 UGC-style
3. Ensure new creative has strong 3-second hooks and captions (85% of Facebook videos watched without sound)
4. Maintain 15-30 active creatives in ASC (max ceiling is 150)

Automation Rules to Add

Rule	Threshold	Action
Fatigue pause	Creative frequency > 5.0 AND 7+ days active	Pause creative
Low performer	Ad CPA > 2x campaign avg AND 100+ clicks	Pause
Creative refresh alert	3+ ads at frequency > 4	Notify team

Monitoring Plan

• Day 3: Verify new creatives are spending and delivering
• Day 7: Check frequency — should be dropping toward 3-4 range as new creatives absorb impressions
• Day 14: ROAS should start recovering toward 3.5-4.0x range as fatigue clears
• Success criteria: ROAS above 3.8x within 21 days, frequency stable below 4.0
• Rollback: If ROAS continues declining after creative refresh, the problem is deeper (tracking issue, offer/product problem, market shift). Use meta-ads-audit skill for full diagnostic.

Guidelines

• Don't optimize during learning phase. 5-7 days minimum. Changes reset learning. The only exceptions are clear tracking failures (stop the bleeding) or disapprovals.
• Don't change budgets by more than 20% at once. Even on winners, larger jumps destabilize Smart Bidding pacing.
• Don't ignore creative frequency. It's the #1 leading indicator of Meta performance decline. Measure at the CREATIVE level, not ad or ad set level.
• Don't over-segment ad sets. 2025 algorithm prefers consolidated ad sets with 50+ conversions/week. Combine warm and cold audiences. Let the algorithm sort.
• Don't run rules without volume minimums. Rules triggering on 5 clicks will false-positive constantly. Require 100+ clicks and 10+ conversions minimum.
• Don't skip tracking checks when performance drops. A "performance issue" is often a tracking issue. Verify Pixel fires, CAPI fires, EMQ is stable before touching campaigns.
• Don't forget CPM context. Meta's avg CPM +9% in 2025. Some rising-CPA cases are partial CPM inflation, not creative/audience failure.
• Offline Conversions API discontinued May 2025. If troubleshooting offline tracking, migrate to standard CAPI with action_source: physical_store or system_generated.
• Attribution API change (October 2025): 7d_view and 28d_view windows removed from Insights API. If reports pull these, update reporting.
• Instant Experience change (June 2025): No longer counts as a landing page view. Don't build funnel metrics assuming it does.
• Cross-references: For tracking issues, use the meta-ads-tracking-setup skill. For creative testing and fatigue management, use the meta-ads-creative-engine skill. For full account diagnostic, use the meta-ads-audit skill. For Google Ads optimization, use the google-ads-optimizer skill. For cross-channel budget allocation, use the ad-spend-allocator skill.
• Confidence: Automation rule thresholds are starting points — calibrate to your account's volume and variance. ASC's ~12% CPA reduction vs manual is a Meta benchmark; results vary significantly by account.
