Transcription boosts SEO, and who doesn't love that? Search engines can't listen to audio, so by publishing transcripts of your podcasts and vodcasts, all of that content can now be read and analyzed by search bots, thereby increasing your web traffic.
Broadening your audience should always be top of mind for all podcasters. What better way to extend your content than by offering transcripts for those who are deaf or hard-of-hearing, people whose first language is not English and have difficulty keeping up with audio, those with situational circumstances, ADD, or Auditory Neuropathy?
Make your content go so much further with transcripts by double-dipping, in a sense. Easily cut and paste the transcript to create show notes, social media posts, blog posts, articles, and more. In addition, your content is more likely to be quoted by external sources if it's easily taken from an already existing transcript of your show.
