The 5 reasons why you should add transcription to a video:

1. Viewers understand the video better with transcription when the video has a lot of background noise.
2. Transcription lets viewers overcome the accent barrier.
3. Google crawls the transcription for keywords and increases your SERP ranking accordingly.
4. Likewise, the video’s YouTube search ranking also improves tremendously with the transcription.
5. You can edit a video faster when you have the transcription. The longer the footage, the higher the time saved.
