A URL prepend (or prefix) is the addition of a URL in front of a URL. This enables you to use third-party analytics services.
For example, if your file URL hosted at Libsyn normally looks like this:
…and you want to have an external service track stats for your show. That company may give you a URL Prepend you can add to your normal file URLs. Let’s say your URL Prepend looks like this:
If the URL Prepend gets added to your regular media file URL, your media file URL will suddenly look like this:
The service must be whitelisted. Keep in mind that sending your listener to another service to track things means that you need to care a lot about that third party service protecting the privacy of you and your listeners. Libsyn’s prepend system whitelists services with prepends that have already been vetted to be GDPR and CCPA compliant. If the service is not part of Libsyn’s whitelist, it cannot be used for a prepend. Currently, the whitelisted services providing prepends are:
- Charisma Media
There is a limit of three prepends. Redirects can be very useful. They can be used for a number of important processes performed for URLs across the internet. However, the internet will only tolerate so many changes of direction before it complains about too many redirects. Libsyn’s system, therefore, will limit you to adding 3 URL prepends to your show’s file URLs.
Don’t add multiple redirects pointing back to the same service. What we mean by that is, even if you have more than one assigned prepend URLs from a company, it doesn’t mean that company supports having a single show sent to their service multiple times. In other words, if you have two Chartable prepends (for example), only add one in Libsyn. Adding both will actually break your file delivery to listeners as it isn’t supported by most third-party services.
So, I have a URL Prepend. How do I add it to my show?
To add a prepend to your show:
Click Settings at the top of your Libsyn account to display the Settings page.
Click Advanced Tools.
In the row for URL Prepends, click Edit.
Add up to three Prepend URLs.
- If you enter a URL that is not whitelisted, the system will give you an error stating that the URL couldn’t be saved as it doesn’t meet specifications. If you still want to add the prepend, please reach out to email@example.com for consideration.
- Once the URL prepends are added, you will see that your file URLs will all be generating with the prepend attached automatically.
