Distributing Podcasts: Publish your own podcasts on Spotify and iTunes
The good news: You do not need lots of marketing to get your podcasts on Spotify and Apple iTunes. Both platforms provide podcast hosts with free tools you can use to broadcast your podcasts.
The bad news: You are not reimbursed for the number of plays your podcast gets. However, you are allowed to place audio advertising in your podcast (for example, “This podcast is sponsored by company XYZ”) and finance the podcast with the revenue from advertising.
