There are a few reasons for transcribing your podcast:

• Posting the transcription of your podcast to your website provides the rich text content for search engines to index. Most search engines do not index your audio file. To get traffic to your site, you need regular, quality text content.
• Your podcast listeners will enjoy having a text version side by side while listening for reference and skim. By providing all the options for your audience, they will remember which podcasts are more user friendly than others. What is important is that the audience is given a choice.
  
• Some people simply prefer to read the content rather than listen. Many use the content as a reference for further studies and research. Reading a transcript can also be helpful if the voices on the podcast are hard to understand.
  
• By transcribing, you are broadening your audience and reaching more people, such as those who are hearing impaired.
  
• The transcribed podcast can be used with banner links in formatted and embedded form for advertising, to sell your podcasts.
  
• Transcribe your podcast into texts in order to e-book and sell them.
