Lookalike Audiences are one of Meta’s most powerful targeting tools. They help you find new potential customers who are similar to your best existing ones.
If you’ve ever wanted to scale your campaigns while keeping quality high — this is your best weapon.
🔍 What Is a Lookalike Audience?
A Lookalike Audience is a group of people who share similar behaviors and characteristics with your source audience (such as buyers, fans, or site visitors).
Meta analyzes your source and finds new users who are “lookalikes” based on:
- Interests
- Online behavior
- Demographics
- Device usage
🎯 Examples of Source Audiences
- Your top 5% customers
- Website visitors (via Pixel or CAPI)
- People who engaged with your Facebook or Instagram pages
- Email subscribers or phone numbers you uploaded
🔧 How to Create a Lookalike Audience
- Go to Meta Business Manager → Audiences
- Click “Create Audience” → Lookalike Audience
- Choose your source audience
- Choose your target location
- Select your similarity percentage:
- 1% = most similar (high quality, smaller reach)
- Up to 10% = broader but less precise
🚀 Best Practices
- Start with a 1% Lookalike of purchasers or high-value users
- Layer with interest targeting for sharper focus
- Test different sizes (1%, 3%, 5%)
- Refresh your source audience regularly
- Combine with Custom Audiences for full-funnel strategies
✅ Why Use Lookalikes?
- Reach new people with a higher chance of converting
- Save time on manual targeting
- Ideal for scaling your ads
- Keeps performance consistent at scale
💡 Final Thought
If Custom Audiences help you retarget, Lookalikes help you expand.
Use them when you’re ready to grow smarter, not just bigger.
