Sharing your videos on social is an easy way to add additional insights to your video and engage with viewers. YouTube makes it incredibly simple for you and others to promote your video across other social networks. To share a video, just click the “Share” tab underneath the video. There you can select where to market the video. YouTube even provides a shortened URL to your video for convenient posting. 
Not only do subtitles and closed captions help viewers, but they also help optimize your video for search by giving you another opportunity to highlight important keywords. You can add subtitles or closed captions by uploading a supported text transcript or timed subtitles file. You can also provide a full transcript of the video and have YouTube time the subtitles automatically, type the subtitles or translation as you watch the video, or hire a professional to translate or transcribe your video.
