Get a monthly Libsyn downloads report for sponsors

1. Click Stats at the top of Libsyn, check that the toggle shows IAB, and use Statistics By Date Range to select last calendar month.
2. Scroll past Downloads by Episode to Downloads per Country, Downloads per User Agent and Downloads per Destination (Advanced Plan and higher); every table below Statistics By Date Range follows the selected dates, and tables such as Downloads by Episode have their own CSV or PDF download.
3. Or click Download Report for the Stats Export zip, which offers only Last 30, 60 or 90 Days or All Time, not a calendar month.
4. Open Episode Totals to compare episodes by their first 7, 30 and 90 days, then copy everything into one sheet for the sponsor, every month.

On the 2nd of every month, give me last month's IAB downloads by country and by listening app, the top 5 episodes of the month and a CSV I can forward to sponsors.

1. 01

   Fix the month and the metric

   The agent sets the first to the last day of the previous month and uses IAB downloads unless you ask for unique. It names the metric in the report, because sponsors compare IAB numbers across hosts.

2. 02

   Total, then split three ways

   get_show_stats gives the month total and the daily curve. get_downloads_breakdown runs for country, user_agent and destination over the same dates, so the three tables add up to the same total.

3. 03

   Rank episodes fairly

   list_episodes finds what was released in the month and get_episode_stats reads each one's first 30 days, so a new release is not beaten by an older episode that simply had more time.

4. 04

   Explain the gaps

   The agent notes that Apple Podcasts is counted inside the Apple Podcasts / Libsyn Classic Feed destination, and that YouTube views are not downloads. On a plan below Advanced the breakdowns fail with a plan error, and the report says so and keeps the totals.

5. 05

   Attach a file when asked

   export_stats_report adds the Libsyn Stats Export zip in csv, xlsb or pdf when a sponsor wants Libsyn's own file, with the nearest fixed range noted next to it.

• Libsyn's country, user agent and destination tables and the Stats Export are part of advanced stats, which come with the Advanced Plan and higher; Basic and Plus show episode, all-time and daily stats.
• Libsyn counts Apple Podcasts through the Apple Podcasts / Libsyn Classic Feed destination, which may also include other directories reading the same feed.
• Libsyn's IAB downloads follow IAB 2.1 guidelines, need at least one minute of content and exclude known datacenter IP ranges, so they normally come out lower than Unique downloads.
• Libsyn lists YouTube views in their own section and does not add them to downloads or any other statistic.
• Libsyn's This Month figure counts from the first of the current month, while Last 30 Days reaches back into the previous month.

Every tool here only reads, so it can run monthly from n8n, Make, Zapier or cron without waiting for your OK.
