What is tagging and how does it work?

A tag is a special kind of link. When you tag someone, you create a link to their timeline. The post you tag the person in may also be added to that person’s timeline. For example, you can tag a photo to show who’s in the photo or post a status update and say who you’re with. If you tag a friend in your status update, anyone who sees that update can click on your friend’s name and go to their timeline. Your status update may also show up on that friend’s timeline.

When you tag someone, they'll be notified. Also, if you or a friend tags someone in your post and the post is set to Friends or more, the post could be visible to the audience you selected plus friends of the tagged person.

Tags in photos and posts from people you aren't friends with may appear in timeline review where you can decide if you want to allow them on your timeline. You can also choose to review tags by anyone, including your friends.
