In 2014, Facebook introduced Business Manager as an easier way for agencies and social media companies to manage multiple Facebook Business Pages and ad accounts. In 2020, the Facebook Business Manager will be even more important, as the platform becomes necessary to use some features of Facebook for business. If you've been putting off making the switch, you might not even know what Facebook Business Manager is.  We don't blame you! It looks pretty daunting from the outside. But Facebook Business Manager is really just a single hub for agencies to manage Facebook accounts outside of personal accounts.
