Podcast analytics questions

Are Castos analytics IAB-compliant?
Yes. Castos analytics are IAB v2-compliant. Downloads are filtered following the IAB v2 podcast measurement guidelines: known bots and data center traffic are removed, preflight requests are ignored, a play has to reach about a minute of audio to count, and repeat downloads from the same listener on the same day count once. That makes your numbers comparable with other IAB-compliant hosts, and they're the numbers sponsors expect.

What is the Followers metric?
Followers counts the unique listeners who receive a new episode within 48 hours of its release, which usually means their app downloads it automatically. It's the best measure of how many people are subscribed and listening regularly. Followers is included on Growth and up.

Can I see where my listeners are?
Yes. The Geographic Stats report shows listens by country and city on a map you can filter by date range.

Does Castos show Spotify data?
Yes. Castos brings in your Spotify listening data, streams and listeners, and shows it next to your download numbers.

Can I send reports to sponsors?
Yes. On Growth and up, you can build and download PDF reports or export CSVs of your listens, episodes, apps, and locations.

Do my old stats come with me if I switch to Castos?
No. Castos can't import historical analytics from another host, so your Castos stats start the day you move. Export any reports you want to keep before you leave your old host.
