Tagging on Facebook is a way to mention and link to another user, page, or group in a post, comment, status update, or photo. When you tag someone, you create a link to their timeline, and the post you tag them in may also be added to their timeline. By tagging someone, you are getting their attention and letting them know you want them to see what you are tagging them in.

Tagging can be done in several ways, including:

• Tagging in a post or comment: To tag someone in a post or comment, start typing their name and select their profile from the dropdown menu that appears. When you tag someone in a post or comment, they will be notified.
• Tagging in a photo: To tag someone in a photo, click on the photo and select "Tag Photo" at the bottom of the picture. Your cursor will become crosshairs, and you can click on the area of the photo you want to tag (such as a persons face) and select them from the dropdown list. In some cases, the owner of the photo has to approve tag requests made by their friends.
• Tagging in a status update: To tag someone in a status update, start typing their name and select their profile from the dropdown menu that appears.

When you tag someone, the post could be visible to the audience you selected plus friends of the tagged person. However, tags in photos and posts from people you arent 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.

Tagging on Facebook can alert followers to posts and encourage engagement. It can also help businesses promote their brand and connect with other businesses and users.
