Transcripts are GREAT ways to add excellent, relevant content to your episode pages. Adding transcripts to your site is a great way to help Google understand what your episode is about.
If you're a Buzzsprout customer, transcripts added there will be automatically imported into Podpage. See info about that here.
If not, you can always manually add them:
Log into your Podpage dashboard
Click Episodes on the left to see your list of episodes
Click Edit on any episodes
Scroll down and past your transcript into the Transcript field
