With Website Builder, you can add Facebook® Personal pages to your website as a promotional tool. First, you must activate Facebook pages through a Facebook account. Once you finish the basic setup at the Facebook website, you can then complete your pages using the Page Designer in Website Builder.
Facebook pages are for business use, and they don't modify your personal profile's content. For more information about Facebook pages, see Facebook's Help Center. For information about connecting Website Builder to your personal Facebook profile, see Adding Facebook.
