Social media marketing has changed the way people advertised and managed their target markets. Business houses use the different types of media platforms online to ensure maximum reach and higher conversion rates. Facebook lookalike audiences are tools that are developed using Pixels and software kits to analyze and segment out preferred users. The tool finds relevant Facebook users by matching their demographics and preferences with audiences already available on your channel/page.  

But these lookalike audiences aren’t just potential new customers — they can also be used to exclude unwanted customers in the future, creating a sort of ad targeting demographic blacklist.
