‘Facebook’s Lookalike Audiences Lets Advertisers Expand Targeting’ – ‘Mashable’

Todd Wasserman says, “Facebook on Tuesday offered advertisers another tool to target consumers on the platform with Lookalike Audiences, a feature that lets them reach users similar to those in their Custom Audience databases.

Launched in late 2012, Custom Audiences lets marketers use existing data like email addresses, phone numbers and user IDs to inform their Facebook strategy. As the name implies, Lookalike Audiences is a tool that alerts advertisers to similar consumers.

In a blog post heralding the new feature, Facebook noted that marketers can buy Custom and Lookalike audiences in conjunction with any ad buy”.
