We all know closed captioning is the feature on your TV, DVD, or online video player that allows you to click a button and see a written transcript of what is being said on the screen. But if you don’t happen to be hearing impaired, closed captioning is often an after thought…but it shouldn’t be.
There are three major benefits from captions on Youtube:
1. It allows hearing impaired viewers to still understand your message.
2. Youtube allows for caption language to be changed, so now your video can be understood by non-English speakers.
3. Captions are SEO gold. Search Engines can not watch videos and understand what is happening, that is why descriptions and keywords are needed. But with captions, the entire video becomes readable to search engines who can then index your video properly allowing it to be seen in the right searches.
And captioning couldn’t be easier. Youtube offers an amazing new captioning service that finally makes captioning simple. Caption Tube  allows you to write and upload captions to any of your youtube videos within seconds. Now there will of course be some work transcribing your video and if you can’t be bothered, there are several low cost services that will transcribe the videos for you. You should begin to consider captioning an essential step in getting your videos discovered.
