Facebook Ads // Lookalike Audiences in 2019

With Lookalike Audiences you can deliver Facebook ads to people with the same demographics and behaviours as your existing customers.

A Facebook Lookalike Audience helps you to find people who are more likely to be interested in the services your business provides.

Lookalike Audiences allows you to reach users who are similar to;

  • People who like your Facebook page
  • Visitors to your website
  • People who engage with your mobile app

In this post we will explain the purpose of a Lookalike Audience and show you how to create a Lookalike Audience.

What are Lookalike Audiences?

Before targeting ads to Lookalike Audiences, it’s important to know what audience characteristics to match, and how close the people in the audience should match those in the original data source that it’s based on.
The two common use cases for Lookalike Audiences are Streamline Prospecting and Surface Your New Biggest Fans.

Streamline Prospecting

This uses a small custom audience to seed a Lookalike Audience that’s optimized for reach. This helps to find people on Facebook who are likely to be interested in your business but you haven’t connected with them yet.

Surface Your New Biggest Fans

This optimizes for similarity to display ads to the people most likely to love what you do or sell. This option helps your budget work more efficiently.

Plant the seed

The seed (or source) audience that you select as the starting place for your audience lets Facebook know what qualities to match with. The size of the audience you select informs Facebook how closely the Lookalike Audience should match the seed audience.

How to Create your Lookalike?

Firstly, to make a Lookalike you have to be the owner of Facebook Business page or have administrator access on a Facebook Ad account.

If you don’t have admin access or are unsure how to add people to your account, you can follow these steps.

Step 1: Seed Audience

A seed audience are people who are highly valuable to your business, like those who make purchases or are actively engaged with your Facebook page.

Your audience will resemble the audience you seed it with, but only pixel-based Lookalikes contain all members of the seed audience.
You can create a seed audience using data from;
  • A custom audience
  • Your customer information
  • Your Facebook Pixel
  • A mobile app
  • Facebook Page fans
