1. What is a Facebook Lookalike Audience?

A Lookalike Audience is a targeting option on Facebook that helps you find new users who resemble your current customers. It works by analyzing your existing audience’s interests, behaviors, and demographics, then finding people who "look like" them.

This tool is super helpful when:
Your original audience list is limited
You want to expand without losing ad effectiveness
You’ve already excluded old users and need fresh leads

2. Create a Lookalike Audience based on Audience

Steps:

Go to Facebook > Audience > Lookalike Audience

You can do this directly in the app.

Choose "Audience Based" as the Lookalike Mode

Select Your Ad Account

Pick the one you’re using for your campaign.

Choose Base Audiences

Pick one or more of your existing audience files
Each file will generate a separate Lookalike Audience

Set Your Target Area

Country-based Targeting
- Combine Countries: One Lookalike Audience for all selected countries
-Separate Countries: One Lookalike Audience per country
Region-based Targeting
-Only one Lookalike Audience will be generated regardless of country settings

Select Audience Size

Ranges from 1% to 20%

Smaller percentages (1-2%) = higher similarity to your original audience

Larger percentages (7-20%) = broader reach but less precise targeting

Notes:

You can select multiple sizes at once—each size creates its own Lookalike Audience.

The smaller the percentage, the higher the match quality.

3. Create a Lookalike audience based on Campaign

Steps:

Access Lookalike Audience from the App

Choose "Campaign Based" as the Lookalike Mode

Select the Campaign and Ad Sets

You can choose one or more

The app will generate just one Lookalike Audience total

Set the Target Area and Audience Size

Same process as in the audience-based setup

Click "Create"

Your Lookalike Audience will sync with your Facebook Business account

Done! What’s Next?

You’ve now created a Lookalike Audience that can help you find new potential customers based on your best-performing audiences or campaigns. This is one of the most effective ways to scale your ads without wasting budget on the wrong crowd.
