Audience measurement with Castopod

Castopod provides great analytics data about your audience.

Castopod respects your listeners privacy. Their IP address is never stored on the server and all data are aggregated before being stored on the server.
With Castopod there is no one between your podcast and your audience.

Castopod follows the IAB Podcast Measurement Technical Guidelines Version 2.0:

  • Rolling 24-hour window
  • Castopod does not do pre-load
  • IP deny list
  • User-agent Filtering
  • Ignores 2 bytes range "Range: 0-1" (performed by official Apple iOS Podcast app)
  • In case of partial content, adds up all requests to check >1mn was downloaded
  • Identifying Uniques is done with a combination of IP Address and User Agent

Please note that Castopod is not certified by IAB and probably never will, since tampering with data is very easy with self-hosted open-source software. (Remember that no third party is involved.)
IAB guidelines were used because they seemed relevant to us and they are a great tool for benchmarking.

All the data from the charts below were added for demo purposes on a testing server.
