Setting Up Your RSS Feed

As you're getting started with your new podcast one of the things that is necessary before you can submit your show to iTunes, Stitcher, or Google Play is to create a valid RSS feed for your podcast. Castos does not automatically distribute your RSS feed and you will need to create an account with the services where you want your show to appear. But once setup, your podcast episodes will publish automatically.

The RSS feed is the place these podcasting directories look to learn about your show as a whole (Title, Description, Keywords, Categories, Cover Image, etc.) as well as information about each episode.

Feed Details

To set up your podcast RSS feed in Castos first create your first Podcast by clicking the Add Podcast button in the Podcast area of your Castos dashboard. If you already have a podcast (or several) you can edit your podcast details by clicking the Edit Podcast link. Here you will be able to enter the details for your podcast. To maximize the SEO value of your podcast in iTunes and other podcasting directories it's best to include as much detail and information in the feed as possible. Things like Keywords and good, relevant descriptions of your show will increase the 'findability' of your show on these platforms.

Cover Image

Your podcast cover image has size specifications set by iTunes or your RSS feed will not validate. The image  must be:

  • square
  • between 1400x1400px and 3000x3000px
  • under 500mb
  • RGB format
  • jpg or png

The most common reason for podcast submissions not being accepted by iTunes is that feed includes a cover image that does not conform to their specifications.

***Note: You can change your podcast cover image at any time by coming back to the Edit Podcast page and clicking the Choose File button below your image***


One of the best ways for new listeners to find your podcast is by being highly ranked within a category.  

iTunes gives you 3 different categories that you can submit your show in, and we HIGHLY recommend that you take advantage of each of these.  This gives your show much broader exposure to potential listeners and is a great way to grow your audience.  


The last important section to set up your RSS feed for your podcast is Distribution. This panel allows you to see your RSS feed URL that you will submit to Apple Podcasts, Google Play, Stitcher and other platforms. This feed is automatically generated and based on your Podcasts Name and Castos Webpage URL.

Once submitted you can place the URL the sections for the subscribe links that are displayed on your Castos podcast webpage (i.e. 

Your Feed

Once your feed has been successfully created we recommend checking it on one of several feed validators.  The easiest to start with is - this is a free RSS feed validator specific for podcasting.  Once you've successfully validated your podcast RSS feed there then before you submit to iTunes you will be able to Validate your feed in iTunes Connect prior to submission.

Castos does not submit your RSS feed to these distribution channels automatically. You need to create an account and submit your URL. Click here to learn how to submit your podcast to iTunes. If you want to publish to Spotify you can use the Castos API or you can create your own account and use your RSS feed to submit.
