What's Included

Lookalike Audience Performance

Lookalike audiences deliver 30-50% lower cost per acquisition than cold targeting while maintaining quality. 1% lookalikes see best results (most similar to seed audience), while 1-10% lookalikes provide scale. Average performance lift: 33% more conversions at 27% lower CPA.

Seed Audience Selection

Build from highest-value sources: Purchase converters (best ROI), high-AOV customers (quality), email subscribers (engaged), website visitors (intent), and video viewers (engagement). Minimum seed size: 100 for Facebook, 1000+ recommended. Refresh lookalikes quarterly.

Layering & Optimization

Advanced targeting: Layer lookalikes with interests, behaviors, demographics for precision. Test 1% vs 1-3% vs 3-5% vs 5-10% audiences. Exclude seed audience, past purchasers, and cart abandoners. Use CBO to automatically allocate budget to best-performing lookalikes.

Platform Strategies

Cross-platform lookalikes: Facebook (broad reach, B2C), LinkedIn (B2B, job title matching), Google (search intent), and Pinterest (visual discovery). Each platform's AI uses different signals - test all for your vertical. Facebook lookalikes tend to perform best for ecommerce and DTC.

Testing & Scaling

Systematic approach: Start with 1% lookalike, measure for 7 days, compare CPA to cold audiences. If 20%+ better, scale budget and test broader percentages. Create multiple lookalikes from different value segments. Track: CPA, ROAS, conversion rate, quality score, and LTV.
