What Are Lookalike Audiences?

A Lookalike Audience is an advanced targeting feature that allows you to find new potential customers who share similarities with your existing audience. Platforms like Meta (Facebook & Instagram) and Google Ads analyze data from your current customers and use AI and machine learning to find new people with similar interests, demographics, and behaviors.

‍

Think of it this way: Imagine you own a successful online fashion store, and you have 1,000 customers who have purchased items in the past six months. A Lookalike Audience will find new people who have similar buying patterns, income levels, interests, and behaviors as those 1,000 customers, increasing your chances of making sales.

Step-by-Step Guide to Creating Lookalike Audiences for Sales Growth

‍

Step 1: Choose a High-Quality Source Audience

Your Lookalike Audience is only as good as the source audience you provide. You need a list of your best-performing customers or engaged users.

‍

Best Source Audience Examples:

 Existing Customers: People who have purchased from you.

 Email List: Engaged subscribers who open and click your emails.

 Website Visitors: Those who have visited your site and spent time browsing.

 Add to Cart & Checkout Abandoners: People who showed high intent to buy.

 Engaged Social Media Users: Those who like, comment, and share your content.

‍

Pro Tip:

For best results, your source audience should have at least 1,000 people but not exceed 50,000 for high accuracy.

‍

Step 2: Upload & Create a Custom Audience

On Facebook (Meta) Ads Manager, follow these steps:

Go to Audiences in your Meta Business Manager

Click Create Audience → Custom Audience

Select a source (Website traffic, customer list, social media engagement, etc.)

Upload your customer list (if using emails) or select website visitors

Name your audience and save it.

Once your Custom Audience is created, you can move on to Lookalike Audiences.

‍

Step 3: Create Your Lookalike Audience

Click Create Audience → Lookalike Audience

Select your Custom Audience as the Source

Choose your target country or region

Select Audience Size (1%-10%)

1% Lookalike = Closest match to your best customers (High quality, but small size)

5% Lookalike = Balanced match with a larger audience

10% Lookalike = Broader audience but slightly less accurate

Click Create Audience

‍

Pro Tip: Start with 1% or 2% Lookalike Audiences for the highest quality leads, then scale up to 3%-5% as your budget increases.

‍

Step 4: Run Ads & Test Performance

Once your Lookalike Audience is ready, you need to launch ads to drive conversions.

Create a new Conversion or Sales Campaign

Under Audience, select your Lookalike Audience

Write compelling ad copy and use high-quality visuals

Track your performance metrics and optimize based on results

‍‍

Pro Tip:
