It's done via RSS feeds that the podcast creators then submit to aggregators. Then apps pull that information down from said aggregators. This website explains the gist of it.
https://rss.com/blog/how-to-create-an-rss-feed-for-a-podcast/
So how do the aggregators sync with each other to get all the podcasts? Or is it up to the podcast to "post" to all the aggregators?
The aggregators don’t sync with each other. The podcast creators upload the new show to each aggregator (or use an app that uploads to multiple).
Okay cool, that I think explains everything I've wondered about this topic lol. Awesome, thank you!
And they don’t even have to go through an aggregator, it’s just for ease of use and discovery, pretty much every app will let you put in an rss feed url, so podcast could be self hosted only reliant on having an internet connection… well, hell…. Only reliant on having a shared network connection with your target audience
The one paid podcast I pay for does this.
You pay on their site and then you get a personal RSS URL to put in your catcher.
