Facebook today expanded its advertising tool Lookalike Audiences to allow advertisers to target new users based on people who visit their websites, use their mobile apps, or are connected to their Facebook Pages. Until now, advertisers could only create “lookalikes” based on existing information like email addresses, phone numbers, and user IDs.

Facebook first announced Lookalike Audiences in March 2013. For those who don’t know, the feature is supposed to help businesses reach potential customers who share “similar characteristics with their current ones,” which the company refers to as “lookalikes.”

Today’s update means advertisers can:

  • Find more people who “look like” their website visitors by using data from their Facebook pixels to reach people who are similar to those who previously made purchases on their website.
  • Find more people who “look like” their mobile app users by creating lookalike audiences based on people that have used their mobile app, such as people who’ve downloaded songs from their music app or have made purchases via their shopping app.
  • Find more people who “look like” their Facebook fans by creating lookalike audiences based on their current fans.

The new features are available today in Power Editor to all advertisers worldwide. To start using them, head to Power Editor, click the “Audiences” tab, and then hit “Create New Audience” → “Lookalike Audience.”

As always with new advertising features, Facebook promises that lookalike audiences “are designed to protect people’s privacy.” This feature lets marketers reach specific groups of people without actually sharing with them who is in those groups.
