# Meta Ads Campaign Builder

## Purpose

This recipe produces a fully configured Meta Ads campaign in Ads Manager — with the correct objective mapped to business goals, audiences built from pixel data, customer lists, and interest signals, compliant creative assets uploaded to spec, and Pixel + Conversions API tracking verified for accurate attribution. The output is a launch-ready campaign delivering ads across Facebook, Instagram, Messenger, and Audience Network with proper conversion tracking. [src1]

## Prerequisites
<!-- Agents: verify ALL prerequisites before executing. Missing prerequisites = failed execution. -->

- [ ] **Meta Business Suite account** — verified business at [business.facebook.com](https://business.facebook.com/) with ad account created
- [ ] **Facebook Page** connected to the Business Suite (required for ad delivery)
- [ ] **Instagram Business/Creator account** connected (required for Instagram placements)
- [ ] **Landing page URL** — live, mobile-responsive page where ad traffic will land
- [ ] **Ad creative assets** — at least 3-5 image or video variants (see creative specs in Step 4)
- [ ] **Payment method** added to the ad account (credit card, PayPal, or manual payment)
- [ ] **Website access** — ability to add code to site header or access to Google Tag Manager (for Pixel installation)

## Constraints
<!-- Hard rules. Agents: enforce throughout execution. Violating these = broken output or legal risk. -->

- Meta Pixel + Conversions API must both be active for reliable conversion tracking. Pixel-only setups miss 40-60% of conversions post-iOS 14.5. [src2]
- Custom Audiences require a minimum of 100 matched users to be deliverable. Seed lists below this threshold will not populate. [src5]
- Ad images: max 30 MB, JPG or PNG. Ad video: max 4 GB, MP4 or MOV. Stories/Reels must be 9:16 aspect ratio. [src4]
- Campaign budget minimum is $1/day per ad set. For meaningful optimization data, budget at least $20-$50/day to exit the learning phase within 7 days. [src3]
- All ads must comply with Meta Advertising Standards — no discriminatory targeting for housing/employment/credit (Special Ad Categories required), no misleading health claims, no before/after imagery. [src1]
- Advantage+ Sales campaigns auto-expand targeting beyond manual audience selections. Do not use for narrowly targeted campaigns where audience control is critical. [src1]

## Tool Selection Decision

<!-- Agent selects the right tool path based on user inputs.
     Each path leads to a different execution flow below. -->

```
Which path?
├── User is non-technical AND budget < $2,000/mo
│   └── PATH A: Ads Manager GUI — manual setup, Advantage+ audiences
├── User is non-technical AND budget >= $2,000/mo
│   └── PATH B: Ads Manager + third-party optimizer (AdEspresso/Revealbot)
├── User is semi-technical AND any budget
│   └── PATH C: Ads Manager + GTM for Pixel/CAPI + manual audiences
└── User is developer AND any budget
    └── PATH D: Marketing API + server-side CAPI + automated rules
```

| Path | Tools | Cost | Speed | Output Quality |
|------|-------|------|-------|---------------|
| A: GUI Basic | Ads Manager, Events Manager | $0 + ad spend | 2-3 hours | Good — relies on Advantage+ AI |
| B: GUI + Optimizer | Ads Manager, AdEspresso or Revealbot | $49-$99/mo + ad spend | 2-3 hours | High — automated testing and optimization |
| C: GTM Integration | Ads Manager, Google Tag Manager | $0 + ad spend | 3-4 hours | High — precise tracking control |
| D: API + Code | Marketing API, server-side CAPI | $0 + ad spend | 4-6 hours | Highest — full automation and custom events |

## Execution Flow

### Step 1: Install Meta Pixel and Configure Conversions API

**Duration**: 30-60 minutes
**Tool**: Meta Events Manager, Google Tag Manager (optional)

Install the Meta Pixel base code on every page of your site. Then configure the Conversions API for server-side event deduplication.

**Pixel installation via Google Tag Manager:**

```html
<!-- Option 1: Direct installation in site <head> -->
<!-- Replace YOUR_PIXEL_ID with actual Pixel ID from Events Manager -->
<script>
!function(f,b,e,v,n,t,s)
{if(f.fbq)return;n=f.fbq=function(){n.callMethod?
n.callMethod.apply(n,arguments):n.queue.push(arguments)};
if(!f._fbq)f._fbq=n;n.push=n;n.loaded=!0;n.version='2.0';
n.queue=[];t=b.createElement(e);t.async=!0;
t.src=v;s=b.getElementsByTagName(e)[0];
s.parentNode.insertBefore(t,s)}(window, document,'script',
'https://connect.facebook.net/en_US/fbevents.js');
fbq('init', 'YOUR_PIXEL_ID');
fbq('track', 'PageView');
</script>
```

**Standard events to configure:**

```javascript
// E-commerce events
fbq('track', 'ViewContent', {content_ids: ['SKU123'], content_type: 'product', value: 29.99, currency: 'USD'});
fbq('track', 'AddToCart', {content_ids: ['SKU123'], content_type: 'product', value: 29.99, currency: 'USD'});
fbq('track', 'Purchase', {content_ids: ['SKU123'], content_type: 'product', value: 29.99, currency: 'USD'});

// Lead generation events
fbq('track', 'Lead', {content_name: 'demo-request'});
fbq('track', 'CompleteRegistration', {content_name: 'signup'});
```

**CAPI setup** — use Meta's partner integrations (Shopify, WordPress WooCommerce, GTM server-side) or implement directly via the Conversions API endpoint. Ensure each event includes an `event_id` matching the browser pixel event for deduplication. [src2]

**Verify**: Open Meta Events Manager > Test Events. Trigger a test conversion on your site. Both Pixel (browser) and Server events should appear with matched `event_id`. Event Match Quality (EMQ) score should be 6.0+.
**If failed**: If only Pixel events fire, check CAPI gateway configuration. If EMQ is below 6.0, add more customer parameters (email hash, phone hash, fbp, fbc cookies). [src6]

### Step 2: Choose Campaign Objective and Structure

**Duration**: 15-30 minutes
**Tool**: Meta Ads Manager

Select the objective that matches your business goal. Meta's 6 objectives in 2026: [src1]

```
Business Goal → Objective Mapping:
├── "I want people to know my brand exists"     → Awareness
├── "I want visits to my website/app"           → Traffic
├── "I want likes, comments, shares, or views"  → Engagement
├── "I want form fills, messages, or calls"     → Leads
├── "I want app installs or in-app actions"     → App Promotion
└── "I want purchases or signups on my site"    → Sales
```

**Campaign structure best practices:**

```
Campaign (1 objective, 1 budget strategy)
├── Ad Set 1: Prospecting — broad/Advantage+ audience
│   ├── Ad 1: Image creative A
│   ├── Ad 2: Video creative A
│   └── Ad 3: Image creative B
├── Ad Set 2: Retargeting — website visitors 30 days
│   ├── Ad 1: Social proof creative
│   └── Ad 2: Offer/urgency creative
└── Ad Set 3: Lookalike — 1% of purchasers
    ├── Ad 1: Image creative A
    └── Ad 2: Video creative A
```

For e-commerce with $2,000+/month budget, use **Advantage+ Sales campaigns** which auto-optimize audience, placement, and creative across up to 150 combinations. [src1]

**Verify**: Campaign objective matches business KPI. Structure has 2-4 ad sets with distinct audiences. Each ad set has 3-6 creative variants.
**If failed**: If only 1 ad set with 1 ad, add at least 2 more creative variants. Meta needs 3+ variants to optimize delivery.

### Step 3: Build Audiences

**Duration**: 30-45 minutes
**Tool**: Meta Ads Manager > Audiences

Build three audience layers: Custom Audiences (warm), Lookalike Audiences (modeled), and Advantage+ / interest-based audiences (cold). [src5]

**Custom Audiences (retargeting):**

```
Source options:
├── Website traffic (Pixel-based)
│   ├── All visitors — last 30 days (broad retargeting)
│   ├── Product viewers — last 14 days (mid-funnel)
│   └── Cart abandoners — last 7 days (high intent)
├── Customer list (CRM upload)
│   ├── All customers (CSV: email, phone, name, city, state, zip)
│   └── High-LTV customers (top 20% by revenue)
├── Engagement audiences
│   ├── Video viewers — 75%+ completion, last 60 days
│   ├── Instagram engagers — last 90 days
│   └── Lead form openers — last 90 days
└── App activity (if applicable)
```

**Lookalike Audiences:**

```
Source audience → Lookalike size:
├── Purchasers (best source)    → 1% Lookalike (highest match)
├── High-LTV customers          → 1% Lookalike
├── Email subscribers           → 1-3% Lookalike (broader)
└── Website visitors            → 3-5% Lookalike (broadest)

Rule: Start at 1% (most similar). Expand to 3-5% only after 1% is
      saturated (frequency > 3.0 in 7 days).
```

**Advantage+ Audience (recommended for prospecting):**
In 2026, use Advantage+ Audience as the default for cold prospecting. Provide audience suggestions (interests, demographics) but allow Meta's AI to expand beyond them. This consistently outperforms manual interest targeting. [src5]

**Verify**: Custom Audiences show status "Ready" with 1,000+ matched users. Lookalikes are created from high-quality seed audiences (purchasers preferred over visitors).
**If failed**: If Custom Audience shows "Too Small" (< 100 matches), use a longer lookback window (180 days) or upload a larger customer list. If match rate on list upload is < 30%, clean data — ensure emails and phone numbers are properly formatted.

### Step 4: Create Ad Creative to Spec

**Duration**: 30-60 minutes
**Tool**: Meta Ads Manager > Ad Creation or Canva/design tool

Upload creative assets matching Meta's 2026 specifications. Provide a minimum of 3 variants per ad set. [src4]

**Image specifications:**

```
Feed (Facebook + Instagram):
  Aspect ratio: 1:1 (square) or 4:5 (vertical, recommended)
  Resolution:   1080x1080 (1:1) or 1080x1350 (4:5)
  Max ideal:    1440x1440 (1:1) or 1440x1800 (4:5)
  File format:  JPG (photos), PNG (text/logos)
  Max size:     30 MB

Stories + Reels:
  Aspect ratio: 9:16 (full-screen vertical, required)
  Resolution:   1080x1920 (minimum), 1440x2560 (ideal)
  Safe zone:    Keep text/logos away from top 250px and bottom 340px
  File format:  JPG or PNG
  Max size:     30 MB
```

**Video specifications:**

```
Feed:
  Aspect ratio: 1:1 or 4:5 (recommended)
  Resolution:   1080x1080 minimum
  Duration:     15-60 seconds (15s optimal for engagement)
  File format:  MP4 or MOV
  Max size:     4 GB

Stories + Reels:
  Aspect ratio: 9:16 (required — non-9:16 reduces engagement ~41%)
  Duration:     Up to 60 seconds (15s sweet spot)
  File format:  MP4 or MOV
```

**Ad copy guidelines:**

```
Primary text:    50-150 characters (125 chars before truncation)
Headline:        Up to 27 characters (40 chars max before truncation)
Description:     Up to 30 characters
CTA button:      Select from predefined options (Shop Now, Learn More,
                 Sign Up, Get Offer, Book Now, Contact Us)
```

**Verify**: All images pass Meta's ad preview without warnings. Video thumbnails display correctly. No text overlay exceeds 20% of image area. CTA button matches campaign objective.
**If failed**: If image rejected, check for policy violations (text density, prohibited content). Re-export at recommended resolution. For video, ensure first 3 seconds have strong hook — 65% of viewers decide to skip within 3 seconds.

### Step 5: Configure Budget, Schedule, and Placements

**Duration**: 15-20 minutes
**Tool**: Meta Ads Manager

Set campaign budget, delivery schedule, and placement selection.

**Budget configuration:**

```
Budget strategy decision:
├── Testing phase (first 2 weeks)
│   ├── Daily budget: $20-$50/day per ad set
│   └── Goal: exit learning phase (50 conversions per ad set per week)
├── Scaling phase (after winning creative identified)
│   ├── Increase budget 20-30% every 3 days (avoid resetting learning)
│   └── Switch to Campaign Budget Optimization (CBO) across ad sets
└── Advantage+ Sales campaigns
    ├── Set total campaign budget, let Meta distribute across audiences
    └── Minimum recommended: $100/day for meaningful AI optimization
```

**Placement selection:**

```
Recommended: Advantage+ Placements (let Meta optimize)
  - Facebook Feed, Instagram Feed, Instagram Explore
  - Stories (Facebook + Instagram), Reels (Facebook + Instagram)
  - Messenger Inbox, Audience Network
  - Right Column (desktop only)

Override only if: specific creative is designed for one surface
  (e.g., vertical-only video → Stories + Reels only)
```

**Verify**: Budget is sufficient to generate 50+ optimization events per week per ad set. Advantage+ Placements enabled unless creative requires specific surfaces. Schedule set to "Run continuously" for evergreen campaigns or specific dates for promotions.
**If failed**: If budget is below $10/day per ad set, consolidate ad sets. Fewer ad sets with adequate budget outperform many ad sets with insufficient budget.

### Step 6: Launch and Verify Tracking

**Duration**: 15-30 minutes
**Tool**: Meta Ads Manager, Meta Events Manager

Publish the campaign and verify all tracking fires correctly in production.

```
Pre-launch checklist:
├── [ ] Campaign objective matches business goal
├── [ ] Audiences are "Ready" status with sufficient size
├── [ ] Creative preview looks correct on all placements
├── [ ] Pixel events verified in Events Manager Test Events
├── [ ] CAPI events firing with matching event_id (deduplication)
├── [ ] UTM parameters added to destination URLs
├── [ ] Payment method active and billing threshold adequate
├── [ ] Special Ad Category selected if applicable (housing/employment/credit)
└── [ ] Campaign status: set to Active
```

**Post-launch verification (within 1 hour):**

```
Check in Ads Manager:
├── Campaign status shows "Active" (not "In Review" for > 2 hours)
├── Impressions > 0 within first hour
├── Link clicks registering if traffic/conversion objective
├── Events Manager shows live events matching ad traffic
└── No policy violation warnings or ad rejections
```

**Verify**: Ads are delivering, impressions accumulating, and conversion events match between Ads Manager and Events Manager. URL parameters (utm_source=meta, utm_medium=paid) visible in Google Analytics.
**If failed**: If ads stuck "In Review" for > 24 hours, check for policy violations or new account restrictions. If no impressions after 2 hours with active status, audience may be too narrow — broaden targeting or increase budget.

## Quality Benchmarks

<!-- How to evaluate if the output is good enough.
     Links to benchmark cards where applicable. -->

| Quality Metric | Minimum Acceptable | Good | Excellent |
|---------------|-------------------|------|-----------|
| Event Match Quality (EMQ) score | > 6.0 | > 7.5 | > 9.0 |
| Creative variants per ad set | 3 | 5 | 8+ |
| Custom Audience match rate (list upload) | > 30% | > 50% | > 70% |
| Campaign Setup Score (Ads Manager) | > 50/100 | > 70/100 | > 90/100 |
| Learning phase exit (50 events/week) | Within 14 days | Within 7 days | Within 3 days |

**If below minimum**: For EMQ below 6.0, add more customer information parameters to CAPI events (email hash, phone hash, external_id, fbp, fbc). For match rate below 30%, clean customer list data format and ensure email/phone normalization. For slow learning phase exit, consolidate ad sets and increase daily budget per ad set. [src2] [src3]

## Error Handling

<!-- Common failures and recovery actions. Agents need this to handle
     execution errors without human intervention. -->

| Error | Likely Cause | Recovery Action |
|-------|-------------|----------------|
| Ad rejected — policy violation | Creative contains prohibited content, misleading claims, or restricted category without Special Ad Category | Review Meta Advertising Standards. Remove flagged content. If housing/employment/credit, enable Special Ad Category. Request manual review. |
| Pixel not firing — no events in Test Events | Pixel code not installed or blocked by consent manager | Verify pixel base code in page source. Check consent banner — pixel must fire after consent. Use Meta Pixel Helper Chrome extension to debug. |
| CAPI events duplicated (double-counting) | Missing event_id for deduplication between Pixel and CAPI | Add matching event_id parameter to both browser Pixel event and server CAPI event. Meta deduplicates on event_name + event_id. [src2] |
| Custom Audience "Too Small" error | Fewer than 100 matched users from source | Extend lookback window (30 → 180 days), upload larger customer list, or use broader engagement source (page engagers vs. purchasers only). |
| Campaign stuck in "Learning Limited" | Insufficient conversion volume (< 50/week per ad set) | Consolidate ad sets to concentrate budget. Switch to a higher-funnel optimization event (e.g., AddToCart instead of Purchase). Increase daily budget. [src3] |
| High CPM (> $40) with low engagement | Audience too narrow, creative fatigue, or seasonal competition | Broaden audience to 3-5% Lookalike or Advantage+ Audience. Refresh creative. Check if competing with Q4/holiday advertisers. [src3] |

Benchmark CPMs by objective (US, 2026): Awareness $8-$15, Traffic $12-$20, Leads $25-$40, Sales $20-$30. Average CPC across all objectives: $0.50-$2.00. [src3]

## Anti-Patterns

### Wrong: Running pixel-only tracking without Conversions API
Pixel-only setups in 2026 miss 40-60% of conversion events due to iOS App Tracking Transparency, browser ad blockers, and cookie restrictions. Campaigns optimizing on incomplete data bid incorrectly and waste budget on the wrong users. [src2]

### Correct: Implement dual Pixel + CAPI with event deduplication
Install both Meta Pixel (browser-side) and Conversions API (server-side) with matching event_id parameters. Meta deduplicates automatically and uses the richer of the two signals. Target EMQ score of 7.5+.

### Wrong: Creating dozens of narrow ad sets with $5/day each
Splitting budget across many ad sets with tiny budgets prevents any ad set from exiting the learning phase. Each ad set needs approximately 50 optimization events per week, which requires sufficient daily budget to generate that volume. [src3]

### Correct: Consolidate into 2-4 ad sets with adequate budget
Use fewer ad sets with at least $20-$50/day each. Let Advantage+ Placements and audience expansion handle optimization. Consolidation gives Meta's algorithm enough data to optimize efficiently.

### Wrong: Using only 1:1 square creative for all placements
Square creative does not fill Stories and Reels placements, creating black bars that reduce engagement by approximately 41%. Meta increasingly prioritizes vertical 4:5 and 9:16 formats. [src4]

### Correct: Provide format-specific creative for each placement type
Upload at minimum: 1:1 or 4:5 for feeds and 9:16 for Stories/Reels. Use Ads Manager's placement asset customization to assign the right creative to each surface.

## When This Matters

Use this recipe when an agent needs to actually build and launch a Meta Ads campaign — not plan a strategy or discuss targeting theory. Requires a live website with landing pages, ad creative assets, and a Meta Business Suite account with payment method. This recipe covers the complete setup from pixel installation through campaign launch.
