Core Rule: Meta Thinks in Weeks, Not Days

Single-day or 3-day fluctuations are normal. Meta rotates audiences, tests delivery patterns, and adjusts. Never make decisions based on less than 7 days of data. Check results weekly, not daily.

The most common way to kill a winning campaign: Making changes every 2-4 days because a metric dipped. Let it run.

Decision Tree 1: CPA Increasing

Trigger: CPA rises 20%+ above target for 2+ consecutive days.

CPA rising?
│
├─ Step 1: Check tracking
│   ├─ Pixel firing correctly? → If broken, fix immediately
│   ├─ CAPI sending events? → CAPI recovers 20-30% of lost conversions
│   └─ Attribution window correct? → B2B needs 7-day click minimum
│
├─ Step 2: Check frequency + creative fatigue
│   ├─ Frequency > 4.0? → Immediate creative refresh
│   ├─ CTR dropped 20%+ from baseline? → Creative fatigue, new concepts needed
│   └─ Frequency 3.0-4.0? → Warning zone, prepare replacement creative
│
├─ Step 3: Check learning phase
│   ├─ Made changes in last 7 days? → Learning phase reset. Wait.
│   ├─ Under 50 conversions this week? → Still in learning. Don't touch.
│   └─ Budget changed > 30%? → Learning phase reset. Roll back.
│
├─ Step 4: Check audience
│   ├─ Audience overlap between ad sets? → Consolidate or add exclusions
│   ├─ Audience saturated (small pool)? → Expand targeting or create lookalikes
│   └─ Irrelevant placements draining budget? → Check Audience Network, exclude if needed
│
├─ Step 5: Check landing page
│   ├─ Page load > 3 seconds? → 20% of clicks drop before page loads
│   ├─ Message mismatch between ad and LP? → Align copy
│   └─ Bounce rate spiked? → LP issue, not ad issue
│
└─ Step 6: External factors
    ├─ Q4 CPM spike? → Accept higher costs or reduce spend
    ├─ New competitor in auction? → CPM increase may be permanent
    └─ Seasonal demand shift? → Adjust expectations

Quick action table:

Cause	Action	Timeline
Tracking broken	Fix CAPI/Pixel, pause until resolved	24-48 hrs
Frequency > 4.0	Refresh creative immediately	24 hrs
Learning phase reset	No changes, wait 7 days	7 days
Audience saturated	Expand targeting, add lookalikes	3-5 days
Landing page issue	Fix LP, don't blame ads	48 hrs
Seasonal CPM spike	Reduce budget or accept	Variable

---

Decision Tree 2: CTR Dropping

Trigger: CTR drops 20%+ from established baseline.

CTR dropping?
│
├─ Creative fatigue (most common cause)
│   ├─ Frequency > 2.5 (cold)? → Fatigue likely. Rotate creative.
│   ├─ Same ads running 14+ days? → B2B creative loses efficiency in 14-21 days
│   └─ Only 1-2 creative concepts? → Algorithm needs variety. Add 3-4 new concepts.
│
├─ Audience exhaustion
│   ├─ Small audience + high frequency? → Expand or pause
│   └─ Same audience running 30+ days? → Refresh or create new segments
│
├─ Ad format stale
│   ├─ All static images? → Test video (9:16 vertical with audio = 12% higher conversions)
│   └─ All video? → Test static carousels or single image
│
└─ Messaging misalignment
    ├─ Offer still relevant? → Check if market/season shifted
    └─ Copy too generic? → Add specificity, urgency, ICP callouts

Fix priority: Creative refresh (highest impact) → New ad formats → Audience expansion → Copy rewrite

---

Decision Tree 3: Lead Quality Bad

Trigger: Leads have wrong job titles, wrong company sizes, personal emails, or say "I don't remember signing up."

Bad lead quality?
│
├─ Form issues
│   ├─ Work email required? → If no, enable immediately
│   ├─ Custom qualification questions? → Add 1-3 (role, company size, budget)
│   ├─ Using "More Volume" form type? → Switch to "Higher Intent"
│   └─ Social amnesia reports? → Add friction (questions + confirmation screen)
│
├─ Targeting issues
│   ├─ Running broad targeting? → Add job title + interest stacking
│   ├─ Advantage+ expanding too wide? → Switch to Original Audience or add "Further Limit Reach"
│   └─ Audience Network enabled? → Disable - often low-quality traffic for B2B
│
├─ Creative issues
│   ├─ Ad copy too generic? → Add ICP specificity ("For B2B SaaS teams with 50+ employees")
│   ├─ Missing "mosquito repellent"? → Creative must filter OUT non-ICP
│   └─ Offer too low-friction? → Move from ebook to calculator/assessment (higher quality)
│
├─ Optimization issues
│   ├─ Optimizing for leads (volume)? → Try optimizing for qualified leads via CAPI
│   ├─ Sending qualified lead events back to Meta? → If no, set up CRM → CAPI pipeline
│   └─ Only counting form fills? → Send MQL/SQL events for better algorithm training
│
└─ Placement issues
    ├─ Check placement breakdown → Which placements drive low quality?
    └─ Feed placements typically higher quality than Stories/Reels for B2B

The nuclear option: If quality is consistently bad across all changes, the offer is wrong. Go back to offer-strategy.md and redesign.

Decision Tree 4: Kill vs Optimize vs Scale

KILL (Pause Immediately)

• Zero conversions after spending 5-10x target CPA
• Frequency > 6.0 with declining performance
• Relevance score "Below Average" in all 3 diagnostic metrics
• ROI < -30% after 7 full days
• Failed to exit learning phase after 14 days

OPTIMIZE (Adjust and Monitor)

• CPA within 20-30% of target but inconsistent
• CTR 0.8-1.5% (room for improvement)
• Learning phase exited but plateaued
• Frequency 2.5-4.0 (creative refresh needed)
• Lead quality mixed (some good, some bad)

Optimization priority: Creative refresh → Audience refinement → Bid/budget adjustment → Landing page → Offer change

SCALE (Increase Budget)

All must be true:

• 50+ conversions/week for 2+ consecutive weeks
• CPA at or below target for 3+ consecutive days
• Frequency < 3.0 (audience not saturated)
• Lead quality confirmed in CRM (not just volume)

---

Scaling Protocol

The 15-20% rule: Increase budget 15-20% every 3-5 days. Never increase > 30% at once (resets learning phase).

Phase 1: Validation (Week 1-2)

• Wait for 50+ conversions in learning phase
• Establish baseline CPA over 7 days
• Verify lead quality in CRM
• Do NOT touch anything

Phase 2: Conservative Scaling (Week 3-4)

• Increase budget 15% every 3 days
• Monitor CPA daily: if increases > 15%, pause scaling
• Continue if CPA stable or improving

Phase 3: Aggressive Scaling (Week 5+)

• Increase budget 20% every 3 days (if performance holds)
• Stop if: frequency > 3.5, CPA increases 2 consecutive days, CTR drops > 15%

If You Break It (Recovery Protocol)

1. Roll back budget 20-30% immediately
2. Let stabilize for 3-5 days
3. Resume scaling at slower pace (10% every 5 days)

Learning Phase Rules

What It Is

Meta needs 50 conversion events per ad set per week to optimize properly. Until then, performance is volatile.

Budget Formula

Daily Budget = (Target CPA × 50 conversions) ÷ 7 days

Examples:
- $20 CPA → $143/day minimum
- $50 CPA → $357/day minimum
- $100 CPA → $714/day minimum

What Resets Learning Phase (Avoid)

• Changing audience targeting
• Budget increase > 30% at once
• Changing ad creative (new image/video)
• Changing optimization event
• Changing bid strategy

What Doesn't Reset Learning Phase

• Small budget adjustments (< 10%)
• Ad copy tweaks (headline, description)
• Pausing ad for < 24 hours

If Stuck in Learning Phase

• Not getting 7+ conversions per day? → Increase budget OR optimize for upper-funnel event (landing page views, form starts)
• Consolidate ad sets (1 ad set with $500/day > 5 ad sets with $100/day)
• Ensure CAPI + Pixel both firing (recovers missed conversions)

Weekly Optimization Cadence

Monday - Performance Review

• Review past 7 days: CPA, CTR, CPM, frequency, lead volume
• Check CRM: lead quality from last week's ads (job titles, companies, MQL rate)
• Identify top 3 performing ads → why are they winning?
• Flag creative fatigue signals (CTR drop, frequency > 3.0)

Wednesday - Creative + Targeting

• Launch new creative variations based on Monday's analysis
• Apply 50/30/20 budget allocation:
  • 50% → Proven winners
  • 30% → Iterative improvements (new hooks on winning concepts)
  • 20% → New concepts (completely different angles)
• Review learning phase status on new ad sets

Friday - Budget + Scaling Decisions

• Scale winners (15-20% budget increase if criteria met)
• Pause underperformers (see Kill criteria above)
• Check budget pacing (spent evenly through week?)
• Prepare next week's creative pipeline

Monthly

• Full account audit (structure, targeting, tracking, budgets)
• CRM deep dive: MQL-to-SQL rates, cost per opportunity, cost per closed-won
• Refresh audience lists (CRM re-exports, new retargeting segments)
• Review offers: still relevant? Market shifted?

Quarterly

• Campaign structure review (consolidation opportunities)
• CAPI + Pixel health check (Event Match Quality score)
• Competitive analysis (new entrants, CPM trends)
• Budget reallocation across channels based on pipeline ROI

The 80/20 Rule for Campaign Management

20% of your campaigns yield 80% of results. Apply this ruthlessly:

1. Identify your 20% - Which campaigns/ad sets/ads actually drive qualified pipeline?
2. Kill the 80% - Not "reduce budget" - pause them entirely
3. Reinvest in winners - Double down on what works
4. Test in controlled batches - 20% of budget goes to new concepts, not scatter-shot launches

Real example: An account needed to 3-5x ROI in 30 days. Solution: paused everything that wasn't driving revenue. The 80/20 applied, and cutting the waste was enough.

Automatic Placements vs Manual for B2B

Recommended B2B Placement Strategy

Campaign Type	Placement	Reasoning
Cold prospecting	Advantage+ (auto) OK	Let Meta find where your ICP responds. Review placement report after 7 days.
Retargeting	Manual: Feed priority	Users need to read, click, engage - Feed is best for consideration.
ABM	Manual: Feed only	Precise messaging, no waste on low-quality placements.
Brand awareness	Advantage+ (auto) OK	Maximize reach across surfaces.

Placements to Watch / Exclude

• Audience Network - Often low-quality traffic for B2B. Test, but exclude if lead quality drops.
• Stories/Reels - Works for awareness, poor for complex B2B messaging. Only use with dedicated 9:16 creative.
• Facebook Feed - Primary B2B placement. Most engagement, best for long copy.
• Instagram Feed - Secondary. Good for visual credibility, decision-maker presence.
