Some YouTube videos are so funny, inspirational or interesting that you immediately want to share them with the rest of the world. You can share a video to your own Facebook Timeline by clicking on the Share to Facebook button under it. Alternatively, you can post a link to a video to someone else's Timeline, to a page or to a group by copying its link on YouTube and pasting it in a new Facebook post.
Click on the Share icon under the YouTube video you want to share.
Select the Share to Facebook icon to open a pop-up window for customizing your post.
Type a message in the *Say Something About This... field if you want to add a custom description or message to your Facebook post. For example, you can use this field to tell your friends why they should watch this video and what you thought of it.
Click on Friends to open a menu for selecting a specific audience for your post. While the default option displays the post to all of your Facebook friends, you can select alternate groups of people from the list, such as Everyone to even allow complete strangers to view your post or Close Friends to display the post only to contacts you added to your Close Friends list.
Select Post to Facebook to share the video on your Timeline.
Click on Share under the YouTube video, place your cursor anywhere in the address to select the link and press Ctrl-C to copy it to your Windows Clipboard.
Visit the Facebook page, group or Timeline to which you want to share the video. Place your cursor in the Write Something... field and press Ctrl-V to paste the link you copied from YouTube. Optionally, enter a message or description to tell your friends or fans more about the video.
Select Post to post the video link to the page, group or Timeline.
