Facebook Pages Manager is a social media application developed by Facebook. This application allows you to control multiple Facebook pages at once.
Developed directly by Facebook themselves, Facebook Pages Manager allows businesses and individuals to create and manage various Facebook pages without having them connected to their personal Facebook account. This is useful for businesses that eventually want to have a manager control the social media accounts for their business without having to have them sign-in to the personal account of a business leader.
Along with getting access to pages without being connected to a personal account, you'll have access to analytics. With analytics, you can get important data like where your visitors are coming from and by how much so you can divide your marketing money correctly.
Overall, Facebook Pages Manager is great for anyone that needs to manage multiple Facebook pages.
