You can connect with people on Facebook by adding friends or liking pages (the difference is explained below). What users see when they open Facebook is called their news feed. When a Facebook friend you have added or a business page you have liked creates a post, it will show up in your news feed.
This news feed is set by default to show you the top posts based on Facebook’s algorithm, but you can also customize it to simply show a timeline of the most recent posts from your friends and the pages you have liked.
