Brands will make it easy for you to separate different kinds of Facebook pages that have nothing to do with each other. For example, if you have different accounts for different countries (Media Injection NL, Media Injection FR and so on), you can create a different brand for the different countries. Another example is an agency. Agencies work with several customers that have nothing to do with each other and shouldn’t intervene with each other. You can create a different brand for every customer.
You can simply add brands by going to ‘Manage settings’, ‘Brands’ and clicking the plus icon in the top right corner. Don’t forget to add channels to the brand, otherwise, the brand will stay empty. Note that a channel can only be added to one brand. After adding channels, you shouldn’t forget to add users to the brands too. Admins have access to all brands, so you won’t have to add these. Just normal users must be added to a brand. You can also give users access to a brand when you add them to the system.
