Want to scale your Meta Ads without starting from scratch every time? Then Lookalike Audiences are your best friend. This powerful feature helps you reach brand-new people who are highly likely to be interested in your business—because they resemble your existing customers.
In this blog, we’ll break down what a lookalike audience is, why it works, and how to build and use it like a pro.
What Is a Lookalike Audience?
A Lookalike Audience is a group of users that Meta creates based on the characteristics of your existing audience. It analyzes your source audience (like your customer list, website visitors, or people who engaged with your content) and finds new people with similar traits.
For example: If your source audience is 1,000 past customers, Meta will find millions of people with similar interests, behaviors, and demographics.
Why Lookalike Audiences Work
- High relevance: You’re targeting people like your proven converters.
- Scalable: Reach thousands or millions beyond your current base.
- Cost-effective: Better targeting = higher ROI, lower ad spend.
Best Source Audiences for Lookalikes
Not all audiences are created equal. Stronger source = better results.
Here are some high-performing source audiences:
- Website visitors (with Meta Pixel)
- Purchase event audience (buyers only)
- Email list or customer list
- Facebook/Instagram engagers
- Video viewers (50% or more watched)
How to Create a Lookalike Audience (Step-by-Step)
Step 1: Go to Meta Ads Manager > Audiences
Step 2: Click “Create Audience” > Lookalike Audience
Step 3: Select a Source
Choose a custom audience like your Pixel data, CRM list, or Facebook page engagement.
Step 4: Choose Location
Pick the country (or region) where you want to find new users.
Step 5: Choose Audience Size
From 1% (most similar) to 10% (larger but less precise). Start with 1% for best match.
Pro Tips for Using Lookalike Audiences
1. Use High-Quality Source Data
More purchases, page views, or interactions = more accurate lookalikes.
2. Segment Lookalikes
Create separate lookalikes for buyers, engagers, and leads. Test each one.
3. Combine with Interests
Layer interests or behavior targeting to narrow down large lookalikes.
4. Refresh Regularly
Update your source data every 30–60 days to keep lookalikes fresh.
5. Exclude Original Audience
Avoid overlap by excluding your custom audience in the ad set.
When to Use Lookalike Audiences
- When scaling campaigns beyond your existing audience
- When launching a new product with limited reach
- When your custom audience is too small or stale
