Similar to how descriptions work, closed captions and video transcripts will make it much easier for search engines to determine the relevance and value of your video. However, the difference with captions is that they have the added benefit of making your videos accessible to people for whom English is not their first language. While transcripts can take a long time to implement, they allow your videos to reach a much wider international audience. YouTube does offer an automated captioning facility, but this is unreliable at best and can misrepresent your content at worst. If you want to learn how to perfect your captions, YouTube has created a very informative guide to help you get it right.
