A Facebook personal profile is what a user creates when they first create their account. A Facebook profile can have followers or friends, or both. You can message a profile whether or not you are connected. Once you build a Page, you can have someone help you manage it, but you should be directly connected (friends). You can’t boost a post or buy an ad. You can create a group, invite members to join, and manage it alone or assign moderators to help.
A Facebook Page is used by a business for promoting the business, celebrity, brand, cause, or politician. A user can only create a Page after creating the personal account. A Page can boost a post or buy an ad. A user can access the Meta Business Suite and schedule posts and/or Stories to either their Facebook Page or Instagram account. A Page can create a group, connecting it to the Page.
