Facebook on Monday launched Business Manager at business.facebook.com, a new tool that lets large advertisers manage all of their ad accounts, Pages, apps, and permissions from one place. Business Manager is currently available to a “limited number” of US advertisers, but the company says it plans to it roll out internationally “within a few weeks.” Since Business Manager integrates all your Facebook advertising campaign management efforts into one tool, here’s what it will show you if you’re advertising for your own company: The Pages, ad accounts and apps linked to your brand. The people on your team who can access these assets to do their job. External partners, like agencies or Preferred Marketing Developers (PMDs), with access to your Pages, ad accounts and apps. If you’re advertising for someone else (say you work for an advertising agency), Business Manager shows all the Pages, ad accounts, and apps that your clients have allowed you to access, as well as all the people on your teams who have access to them.
