# Paid Acquisition Playbook

## Purpose

This recipe sets up and operates paid advertising campaigns on Google Ads, Meta Ads (Facebook/Instagram), and LinkedIn Ads — with platform-specific setup guides, campaign structures, targeting strategies, benchmark CPAs by industry, and optimization workflows. The output is live advertising campaigns with conversion tracking, proper targeting, and a weekly optimization process that drives predictable customer acquisition within CPA targets. [src1]

## Prerequisites

- [ ] **Landing page** optimized for conversion goal — fast-loading, clear CTA, mobile responsive — with conversion tracking pixel installed
- [ ] **ICP definition** with demographics and firmographics — [ICP Definition Framework](/business/customer-research/icp-definition-framework/2026)
- [ ] **Marketing strategy** confirming paid as a channel with allocated budget — [Marketing Strategy Framework](/business/startup-marketing/marketing-strategy-framework-for-startups/2026)
- [ ] **Google Analytics 4** installed with conversion events configured
- [ ] **Ad platform accounts** created: [Google Ads](https://ads.google.com), [Meta Business](https://business.facebook.com), [LinkedIn Campaign Manager](https://www.linkedin.com/campaignmanager)
- [ ] **Minimum $500/platform** for initial testing budget

## Constraints

- Minimum $500-1000 test budget per platform before evaluating — smaller budgets lack statistical significance for optimization. [src5]
- Google Ads average CPA: $40-50 (search), $75 (display). B2B SaaS: $100-200. CPA rose 12% YoY in 2025. [src1] [src7]
- Meta Ads average CPA: $30-40 (B2C), $100-150+ (B2B). Costs rose 8-12% YoY. [src2]
- LinkedIn Ads CPC: $5-8 (2-3x Google). Only viable for B2B with ACV > $5K or LTV > $15K to justify costs. [src6]
- Conversion tracking must be configured before spending any budget. Untracked spend is wasted spend. [src3]
- Do not scale budget more than 20% per week — larger jumps destabilize algorithm optimization (especially Meta's Advantage+). [src2]

## Tool Selection Decision

```
Which platform(s)?
├── B2B SaaS (ACV < $5K)
│   └── Google Search Ads (high intent) + Meta retargeting
├── B2B SaaS (ACV $5K-50K)
│   └── Google Search + LinkedIn Ads (firmographic targeting)
├── B2B SaaS (ACV > $50K)
│   └── LinkedIn Ads (primary) + Google Search (branded + competitor)
├── B2C SaaS / App
│   └── Meta Ads (primary) + Google Search (branded)
├── E-commerce
│   └── Google Shopping + Meta Ads + Google Search
├── Marketplace
│   └── Meta Ads (demand side) + Google Search (intent capture)
└── Developer tools
    └── Google Search (primary) + Reddit Ads (community)
```

| Platform | Best For | Avg CPC | Avg CPA | Min Budget/mo | Setup Time |
|----------|---------|---------|---------|--------------|-----------|
| Google Search | Intent capture (searching for solutions) | $2-5 | $40-200 | $500 | 2-3 hours |
| Google Display | Retargeting, brand awareness | $0.50-2 | $50-100 | $300 | 1-2 hours |
| Meta Ads | B2C acquisition, lookalike audiences | $0.50-3 | $20-150 | $500 | 2-3 hours |
| LinkedIn Ads | B2B with firmographic targeting | $5-8 | $75-300 | $1000 | 2-3 hours |

## Execution Flow

### Step 1: Set Up Conversion Tracking

**Duration**: 30-60 minutes per platform
**Tool**: Google Tag Manager + platform pixels

Set up conversion tracking on every platform before creating any campaigns. This is non-negotiable. [src3]

```
Google Ads Conversion Tracking:
─────────────────────────────────────────
1. Google Ads → Tools → Conversions → New conversion action
2. Choose "Website" → enter conversion URL or use GTM
3. Set conversion value (LTV-based: e.g., $500 for SaaS signup)
4. Set attribution model: Data-driven (default, recommended)
5. Link GA4 property: Google Ads → Linked accounts → GA4
6. Install Google Ads conversion tag via GTM:
   - Trigger: form submission or thank you page view
   - Tag: Google Ads Conversion Tracking

Meta Ads Pixel:
─────────────────────────────────────────
1. Meta Business Suite → Events Manager → Connect Data Sources
2. Install Meta Pixel via GTM or directly in <head>
3. Configure standard events: Lead, CompleteRegistration, Purchase
4. Set up Conversions API (server-side) for iOS 14+ accuracy
5. Verify with Meta Pixel Helper Chrome extension

LinkedIn Insight Tag:
─────────────────────────────────────────
1. Campaign Manager → Account Assets → Insight Tag
2. Install tag via GTM or directly in <head>
3. Set up conversion tracking: URL-based or event-based
4. Define conversions: Sign Up, Demo Request, Content Download
```

**Verify**: Fire test conversions on each platform. Google Ads: check "Conversions" column shows data. Meta: Events Manager shows events firing. LinkedIn: Insight Tag shows "Active".
**If failed**: Use Google Tag Manager debug mode to verify tags fire on correct triggers. Check for ad blockers interfering with pixel loading.

### Step 2: Build Campaign Structure

**Duration**: 1-2 hours per platform
**Tool**: Ad platform dashboard

**Google Ads Campaign Structure:** [src3] [src4]

```
Account
├── Campaign 1: Brand Search
│   ├── Ad Group: [Brand Name] keywords
│   └── Budget: 10-15% of total (protect brand terms)
│
├── Campaign 2: Competitor Search
│   ├── Ad Group: [Competitor 1] alternative
│   ├── Ad Group: [Competitor 2] alternative
│   └── Budget: 20-30% of total
│
├── Campaign 3: Non-Brand Category Search
│   ├── Ad Group: [Problem/solution keywords]
│   ├── Ad Group: [Product category keywords]
│   └── Budget: 40-50% of total (main growth driver)
│
├── Campaign 4: Retargeting (Display)
│   ├── Ad Group: Website visitors (last 30 days)
│   ├── Ad Group: Pricing page visitors (last 14 days)
│   └── Budget: 10-15% of total
│
└── Campaign 5: Performance Max (optional)
    └── Budget: 10-20% of total (test after manual campaigns)

Bid strategy progression:
1. Start: Manual CPC or Maximize Clicks (learning phase)
2. After 30+ conversions: Switch to Target CPA
3. After 100+ conversions: Test Target ROAS or Maximize Conversions
```

**Meta Ads Campaign Structure:** [src2]

```
Account
├── Campaign 1: Prospecting — Broad
│   ├── Ad Set: Lookalike 1% (from customer list)
│   ├── Ad Set: Interest-based targeting
│   ├── Ad Set: Advantage+ Audience (AI-optimized, broad)
│   └── Budget: 60-70% of total
│
├── Campaign 2: Retargeting
│   ├── Ad Set: Website visitors (7-30 days)
│   ├── Ad Set: Engaged with ads/page (90 days)
│   └── Budget: 20-30% of total
│
└── Campaign 3: Testing (CBO)
    ├── Ad Set: New audience tests
    └── Budget: 10% of total (creative and audience experiments)

Optimization tips:
• Use Advantage+ placements (let Meta optimize across FB, IG, Messenger)
• Start with broad targeting — Meta's algorithm finds converters
• 3-5 ad creatives per ad set (mix of image, video, carousel)
• Use UTM parameters on all ad URLs for GA4 attribution
```

**LinkedIn Ads Campaign Structure:**

```
Account
├── Campaign 1: Sponsored Content — Decision Makers
│   ├── Targeting: Job titles (VP, Director, C-level)
│   ├── + Company size (50-5000 employees)
│   ├── + Industry filter
│   └── Budget: 60% of total
│
├── Campaign 2: Sponsored Content — Practitioners
│   ├── Targeting: Job functions + seniority
│   └── Budget: 25% of total
│
└── Campaign 3: Retargeting
    ├── Targeting: Website visitors + video viewers
    └── Budget: 15% of total

LinkedIn-specific rules:
• Minimum audience size: 50K+ for sponsored content
• Use Lead Gen Forms (higher conversion than landing page)
• CPC bidding recommended — avoid CPM for lead gen
• Exclude current customers using company list upload
```

**Verify**: Campaign structure matches the templates above with proper targeting, budgets, and conversion actions assigned. Preview ads on all device types.
**If failed**: If campaigns are rejected, check ad copy for policy violations (Google, Meta, and LinkedIn each have specific ad policies). Fix flagged issues and resubmit.

### Step 3: Create Ad Creative and Copy

**Duration**: 1-2 hours
**Tool**: Canva + ad platform editors

```
Ad Copy Framework (AIDA for paid ads):
─────────────────────────────────────────
Headline (Attention):
  • Lead with benefit, not feature
  • Include number or specific result
  • Match search intent (Google) or stop the scroll (Meta)
  Good: "Cut Onboarding Time by 60% — Free Trial"
  Bad: "Project Management Software — Sign Up Now"

Description (Interest + Desire):
  • Address specific pain point
  • Include social proof (customers, results)
  • Create urgency without being spammy
  Good: "Join 5,000+ teams using [Product] to ship 2x faster.
         14-day free trial. No credit card required."

CTA (Action):
  Google: "Start Free Trial" / "Get a Demo" / "See Pricing"
  Meta: Use platform CTA buttons (Sign Up, Learn More, Get Offer)
  LinkedIn: "Download Guide" / "Request Demo"

Creative formats by platform:
  Google Search: 15 headlines (30 chars each), 4 descriptions (90 chars)
  Meta: Image (1080x1080), Video (15-30s), Carousel (3-5 cards)
  LinkedIn: Single image (1200x627), Video, Carousel, Document
```

**Verify**: Minimum 3 ad variations per ad group/set. All ads have UTM parameters. Landing page matches ad messaging (no disconnect between ad promise and page content).
**If failed**: If CTR is below 2% on search or below 1% on social after 1 week, rewrite headlines to be more specific and benefit-focused. Test radically different approaches, not minor variations.

### Step 4: Launch with Controlled Budget

**Duration**: 15 minutes to launch, 1-2 weeks learning phase
**Tool**: Ad platform dashboard

```
Launch Checklist:
─────────────────────────────────────────
□ Conversion tracking verified (test events firing)
□ Budget set to daily amount (total monthly / 30)
□ Bid strategy set to learning mode (manual CPC or maximize clicks)
□ Geographic targeting confirmed
□ Device targeting: all devices (optimize later with data)
□ Ad schedule: all hours (optimize later with data)
□ Negative keywords added (Google): irrelevant terms, "free" if paid product
□ Frequency cap set (Meta display): 3-5 impressions per user per week
□ All ads approved by platform review

Budget pacing by phase:
  Week 1-2: 50% of planned budget (learning phase — data collection)
  Week 3-4: 75% of planned budget (optimization phase)
  Week 5+:  100% of planned budget (scaling phase)

  Never increase budget by more than 20% per week.
```

**Verify**: Campaigns are live and spending. Impressions, clicks, and conversions are being tracked. No campaigns stuck in "Learning" for more than 7 days.
**If failed**: If not spending, check targeting (audience too narrow), bid (too low for auction), or ad approval status. If "Learning" persists, increase budget or broaden targeting.

### Step 5: Weekly Optimization Cycle

**Duration**: 1-2 hours weekly
**Tool**: Ad platform dashboard + reporting spreadsheet

```
Weekly Optimization Checklist:
─────────────────────────────────────────
Performance review (30 min):
□ CPA by campaign vs target — pause campaigns 2x+ above target
□ CTR by ad — pause ads below 1% (search) or 0.5% (social)
□ Conversion rate by landing page — flag pages below 2%
□ Budget pacing — on track, underspending, or overspending?
□ Quality Score (Google) — fix keywords below 5/10

Optimizations (30-60 min):
□ Add negative keywords (Google): search terms report → irrelevant queries
□ Adjust bids: increase on high-converting keywords, decrease on low
□ Pause underperforming ads: replace bottom 25% with new creatives
□ Audience refinements: exclude non-converting demographics
□ A/B test: launch 1 new ad creative or landing page variant per week

Monthly deep review (2 hours):
□ Calculate blended CPA across all platforms
□ Compare CPA to industry benchmarks (see Cost Breakdown)
□ Evaluate channel mix: reallocate budget from worst to best platform
□ Review attribution: first-click vs last-click vs data-driven
□ Forecast: project next month costs at current efficiency
```

**Verify**: CPA trending down or stable week-over-week. At least 1 A/B test running at all times. Negative keyword list growing weekly (Google). [src4]
**If failed**: If CPA is consistently 2x+ above target after 4 weeks: narrow targeting, test completely different ad creative, or evaluate if landing page is the bottleneck (run a landing page A/B test).

### Step 6: Scale Winning Campaigns

**Duration**: Ongoing
**Tool**: Ad platform dashboard

```
Scaling Decision Framework:
─────────────────────────────────────────
Ready to scale if ALL true:
□ CPA below target for 2+ consecutive weeks
□ 50+ conversions in the campaign
□ Positive ROAS (or CPA < 1/3 of LTV)
□ Conversion rate stable (not declining)

Scaling tactics:
1. Increase budget 15-20% per week (gradual)
2. Expand to new ad groups/audiences within same platform
3. Add new platform (if only on 1 platform, add a second)
4. Launch lookalike audiences (Meta) from converter list
5. Expand geographic targeting (if currently limited)
6. Test new campaign types: Performance Max (Google), Advantage+ (Meta)

Warning signs to pause scaling:
• CPA increasing 20%+ after budget increase
• Conversion rate dropping while traffic increases
• Frequency > 5 per user per week (ad fatigue)
• Quality Score declining (Google)
```

**Verify**: Scaling produces proportional increase in conversions without CPA degradation. If CPA rises > 15% during scaling, pause increase and let campaigns stabilize.
**If failed**: Reduce budget to last stable level. Let campaigns stabilize for 1 week before attempting to scale again with smaller increments (10% instead of 20%).

## Quality Benchmarks

| Quality Metric | Minimum Acceptable | Good | Excellent |
|---------------|-------------------|------|-----------|
| Conversion tracking | Pixel installed | All events tracked + server-side | Full attribution model |
| CPA vs target | Within 2x target | Within 1.5x target | At or below target |
| CTR (search) | > 2% | > 4% | > 6% |
| CTR (social) | > 0.5% | > 1% | > 2% |
| Landing page conversion rate | > 1% | > 3% | > 5% |
| A/B tests running | 0 | 1 per week | 2+ per week |
| Quality Score (Google) | > 5/10 | > 7/10 | > 8/10 |
| ROAS | > 1x (break even) | > 3x | > 5x |

**If below minimum**: Fix conversion tracking first, then landing page conversion rate, then ad creative CTR. Optimize in this order — upstream fixes have the largest impact.

## Error Handling

| Error | Likely Cause | Recovery Action |
|-------|-------------|----------------|
| Ads not spending | Audience too narrow, bid too low, or ad rejected | Broaden audience (increase size 2-3x). Raise bid to platform suggestion. Check ad approval status. |
| High impressions, zero conversions | Landing page issue or wrong audience | Test landing page directly (does it convert from other sources?). Check audience alignment with ICP. |
| CPA 3x+ above benchmark | Targeting too broad, weak creative, or poor landing page | Narrow targeting to highest-intent segments. Test new ad creative. A/B test landing page. [src1] |
| Conversion tracking shows 0 | Pixel not firing or wrong event configured | Use GTM debug mode, Meta Pixel Helper, or LinkedIn Insight Tag debugger to verify. |
| Campaign stuck in "Learning" | Insufficient conversion volume (< 50/week) | Increase budget, broaden targeting, or switch to broader conversion action (e.g., page view instead of purchase). |
| Ad account suspended | Policy violation or payment issue | Review violation notice. Fix flagged ad. Update payment method. Appeal if false positive. [src3] |
| CPA rising while scaling | Budget increase too aggressive or audience exhaustion | Reduce to last stable budget. Expand to new audiences. Refresh creative (ad fatigue). |

## Anti-Patterns

### Wrong: Launching paid ads without conversion tracking
Spending $2K+ on ads with no way to measure which clicks become customers. Result: no data for optimization, no ability to calculate ROI, pure guesswork on what works. [src3]

### Correct: Set up conversion tracking before spending a single dollar
Install and verify conversion tracking on all platforms (Step 1) before launching any campaign. Test with a real conversion. Only then start spending.

### Wrong: Starting with broad targeting and high budget
Launching with $5K/mo on broad audiences on day one. The algorithm has no data to optimize, and money is spent on irrelevant audiences during the learning phase. [src5]

### Correct: Start narrow, then expand
Begin with your highest-intent audience segment and $500-1K/mo test budget. Let algorithms learn (2-4 weeks). Expand targeting and budget only after achieving target CPA.

### Wrong: Judging paid ads after 3 days
Pausing campaigns after 3 days because CPA is too high. Algorithms need 50+ conversions to optimize, and early CPA is always inflated during the learning phase. [src2]

### Correct: Give campaigns 2-4 weeks and 50+ conversions
Set clear evaluation criteria before launching: "This campaign succeeds if CPA < $X after 50 conversions or 4 weeks, whichever comes first." Do not make judgment calls during the learning phase.

Requires a landing page, ICP definition, and budget allocation as inputs. This recipe handles paid ad execution, not overall marketing strategy.
