Prefixes in RSS feeds are a way to add a service, typically a tracking product to your podcast. While most prefixes are safe to add to your show, they can also be used to track, redirect or insert content in your podcast. In addition, too many prefixes for the same show can generate download issues in some podcasting apps and directories.
At RSS.com, we give our users the freedom of adding external tools, third-party services and custom prefixes. If you would like to add a Podtrac prefix to your show, please contact our Customer eXperience team at email@example.com.
