1. Viewers with a hearing impairment would love to access your content.
People who are deaf and hard-of-hearing love YouTube as much as the next person. Images often fill in the blanks to make content more colorful for those who can't hear sounds.
Adding captions to a video certainly helps. But a full transcript of a YouTube video presents all the information in one easy-to-access file. Win over viewers who don't speak your language fluently.
2. Win over viewers who don't speak your language fluently.
As with captions, YouTube subtitles are a great option if you want to reach a global audience.
But offering a YouTube transcript may suit some viewers better. Instead of reading subtitles, a viewer may find it easier to read the full text or script all in one document. They can even use software to translate the transcript and read the whole thing in one sitting.
3. Help Google recognize your YouTube channel and videos.
Do you host videos on YouTube? In order to get search engines to recognize your YouTube channel and content, you must transcribe your videos so they can be indexed. Research shows that videos with transcripts consistently rank higher in search results.
As of this writing, search engines can't crawl through an audio file to identify keywords. Google, Bing, Yahoo, and others recognize written words, not sounds. Although technology will probably appear someday that lets search engines identify spoken language, it's not going to happen anytime soon.
Simply put, any video you post doesn't really count very much to Google. Unless you add text, that is.
That's why YouTube lets channel managers post a description of each video. But think how much more written content you can offer the search engines if you post a full YouTube transcript!
When you transcribe a YouTube video, you make it easier get your content indexed. And you know that more views equal higher Google ranking equals more views.
4. Get an automatic video script after the fact.
Why would you need a video script after producing a video? For many reasons.
First, you can analyze the script and see where better wording might help future videos get more views. If a particular video performs phenomenally, you might want to pinpoint just why it does.
Second, you can use a YouTube transcript as a template for producing future videos. The transcript can serve as an outline for your scriptwriters.
Third, you can post your video transcript in the form of a blog post. Although video content is popular, some of your audience members may still prefer to read a blog. Others may wish to do both. By offering a transcript, you satisfy everyone.
5. Keep a backup of your YouTube videos on file in different formats.
Tech stuff happens. Hackers hack. Videos disappear.
If you keep a YouTube transcript on file, you'll always have something to go back to when your video fails you.
Also, videos take up more storage space than text files do. It's easy to store all of your video transcripts in a small space on a separate drive or server. That way, if anything should happen to your data in one location, you can still recover your transcripts.
