Lookalike Audience

What Is Lookalike Audience?

A Lookalike Audience is a targeted audience segment created by an advertising platform, such as Facebook or Google Ads, that resembles an existing customer base or audience. These platforms use algorithms to identify common characteristics, behaviors, and demographics of your current audience and find new potential customers with similar traits.

Key Features

  • Based on Existing Data: The audience is built using data from your current customers, website visitors, or social media page engagement.
  • Highly Targeted: Helps reach people who are more likely to be interested in your products or services.
  • Customizable: You can adjust the similarity threshold to balance broader reach and high similarity to your original audience.


  • Improved Targeting: Increases the chances of reaching new potential customers who are more likely to convert.
  • Efficient Advertising Spend: Optimizes ad budget by focusing on a relevant audience.
  • Scalability: Helps expand your customer base by finding new people similar to your best customers.


If you have a list of customers who have purchased a product from your online store, you can use this list to create a Lookalike Audience. The platform will then find other users with similar online behaviors and demographics, allowing you to target them with your ads.

Overall, Lookalike Audiences is a powerful tool for businesses looking to scale their marketing efforts and reach new, high-potential customers.

How To Find A Lookalike Audience

Select a Source Audience:

  • Customer Lists: Use lists of your existing customers, email subscribers, or leads.
  • Website Traffic: Utilize data from website visitors tracked by pixels (e.g., Facebook Pixel, Google Tag Manager).
  • Engagement Audiences: Include people engaged with your content on social media platforms.

Upload or Select Source Data:

  • Upload Lists: For platforms like Facebook or Google Ads, you can upload customer lists securely.
  • Use Pixels: Ensure tracking pixels are installed on your website to gather visitor data.

Create the Lookalike Audience:

  • Platform Tools: Use the ad platform’s tools (e.g., Facebook Ads Manager) to create a lookalike audience.
  • Define Audience Size: Choose the audience size, typically from 1% to 10% of the total population in your target country. Smaller percentages are more similar to your source audience, while larger percentages are broader.

Set Campaign Parameters:

  • Location: Specify the geographic location for the lookalike audience.
  • Additional Filters: Apply additional filters like age, gender, or interests if needed.

Why Lookalike Audiences Are Important For Marketers

Improved Targeting:

  • Precision: Lookalike audiences help marketers reach new potential customers who share characteristics with their best existing customers, increasing the likelihood of engagement and conversion.


Higher Conversion Rates:

  • Relevance: Since the audience is similar to those who have already shown interest in your products or services, the likelihood of conversion is higher compared to broader targeting.


Cost-Effective Advertising:

  • Optimized Spend: By targeting individuals who are more likely to be interested in your offerings, you can achieve better results with your ad budget, reducing waste and improving ROI.



  • Expansion: Lookalike audiences enable businesses to expand their customer base efficiently, reaching new segments that resemble their most valuable customers.


Enhanced Campaign Performance:

  • Better Metrics: Campaigns targeting lookalike audiences often see improved performance metrics, such as higher click-through rates (CTR) and lower cost per acquisition (CPA).



  • Automation: Lookalike audiences automate finding new potential customers, saving marketers time on manual segmentation and targeting efforts.


Data Utilization:

  • Leverage Insights: Marketers can use existing customer data to gain valuable insights that can inform and enhance their advertising strategies.


A small e-commerce store selling handmade jewelry can use its customer email list to create a lookalike audience on Facebook. This new audience will include individuals with similar demographics and online behaviors as their current customers, helping the store to target potential buyers more effectively and expand its customer base.

In summary, lookalike audiences are a powerful tool for marketers, enabling precise targeting, higher conversion rates, cost-effective advertising, and efficient scaling of

their marketing efforts. By leveraging data from existing customers, marketers can reach new, high-potential audiences more likely to engage with their brand and become loyal customers.
