Tag Review is a privacy option that lets you approve or reject tags that friends add to your posts. When you turn it on, then anytime a friend wants to add a tag to a photo or post you make, that tag won't appear until you approve it.

To turn on Tag Review:

1. Click the account menu at the top right of any Facebook page and choose Privacy Settings.
2. Under the How Tags Work section, choose Edit Settings.
3. Click to edit your Tag Review setting.
4. Turn on Tag Review.

When Tag Review is on, you’ll get a notification every time you have a post to review. You can approve or ignore the tag request by going to the content itself.

When Tag Review is off, you can skip reviewing tags friends add to your content before they appear on Facebook. When someone who you're not friends with adds a tag to one of your posts you'll always be asked to review it.

Remember: when you approve a tag, the person tagged and their friends can see your post.
