There are three main ways.
Here's the most straightforward, for when the podcast is already on Podscribe:
Find your publisher page on Podscribe by typing it in at the top until the name pops up below, or by searching for it in the publisher tab.
Click on Ad Show/YouTube Channel
Type in the show name until it pops up, then click on it.
Click Add. That's all!
If you add the wrong show (or taking screenshots for a tutorial), you can delete a show by searching for it and then clicking the trash can icon.
Follow steps 1-3 from above, except this time click on Add youtube by playlist/channel url or Podcast by Itunes ID
Find the show on Apple Podcasts, and then copy its link.
Copy the ID number at the end of the URL. For example, the ID for Wiser Than Me would be 1678559416. No need for the letters “id” to be added! Just the numbers.
podcasts.apple.com/ca/podcast/wiser-than-me-with-julia-louis-dreyfus/id1678559416
Paste into the field that lets you add an iTunes ID. Then click ADD
.
Double check that it's been added by searching for it on your show page.
It's also recommended that you check the show page itself to see that all episodes have been added.
