Indexing
Technically, podcasts are XML files that index the MP3 files and metadata that represent each episode. Content management systems like Squarespace and the aforementioned WordPress, with a plugin like podPress, can generate a podcast XML feed. Regardless of which way you author your podcast’s XML file, be sure to follow Apple’s podcast specifications for the best results. Afterward, once your XML file is online, use an RSS validator like feedvalidator.org to make sure you didn’t make any mistakes before submitting your feed to the iTunes store. Don’t forget to submit your show to other podcast platforms, including Google Music, Stitcher, and Soundcloud.
