Every time your friends tag you on Facebook, you will receive a notification on your activity log (click on the globe icon) and your timeline will also be updated by default. If you want to review and approve posts from anyone (including your friends) before they appear on your timeline, you may want to enable Timeline Review. Posts may already appear in other places on Facebook (and will remain there), but they won't appear on your timeline until you approve them. When you have a post to review, it will show up in your activity log. You can enable Timeline Review in your Privacy Settings. Note that tags from non-friends require your approval before they appear on your timeline, even when Timeline Review is off. Make sure you understand how Facebook tagging works and actively monitor status updates that you are tagged in. This can help preserve your online reputation in the event embarrassing or damaging content about you is posted on Facebook.
