Why would you want to add captions to your YouTube videos? I can think of a few reasons:
- Your videos become accessible to people who cannot hear.
- Your videos become more accessible to search. (Check out this search for three terms that only appear in the captions for this video. They’re not in the description text.)
- People watching your videos in an office/library can do so without headphones.
- Non-native speakers may find it easier to read the text.
- Captions can be translated (manually or automatically) into other languages, becoming subtitles and expanding your audience without you having to create multiple videos for multiple languages.
- Fun hacks.
