Too Long; Didn't Read
Facebook Ads allows advertisers to target users across all of Facebook’s main properties; Facebook itself, Instagram, Messenger and (soon) WhatsApp. Facebook has been cutting down on certain targeting options that pose too much of a threat to user privacy. Facebook itself doesn’t offer these targeting options, but they are available via third party tools such as LeadEnforce. Leadenforce offers advertisers the ability to pick specific Facebook groups or pages whose fans they want to target. It pulls together an audience of all of the people they can find who are members of that group, or who like the relevant page.
