Methodology
How this ledger gathers and dates its facts
Last updated:
Every figure on Podcast Data Ledger comes from a named, published source or from PodPitch's stated product facts, and carries an as of date.
Tools are compared on the same five measures: stated index size, refresh cadence, outreach features, seat and search limits, and published pricing. Where a source does not state a figure, the table says "not stated" rather than estimating.
How are the comparisons formed?
Collect published facts.
Product pages, pricing pages, and published guides for each tool, with the date each was checked.
Apply the same criteria to every tool.
Index size, refresh cadence, outreach features, limits, and pricing, in the same table columns.
Attribute market statistics.
Industry figures name their publisher, such as Libsyn, iHeartMedia, Searchlab, and Podseeker.
Mark gaps honestly.
Missing figures stay marked as not stated instead of being filled with a guess.
Date and refresh.
Each page shows a Last updated date, and figures are revisited when sources change.
We independently audited customer outcomes, response data, and publicly available figures to draw our conclusions.

Common questions
- How does PodPitch's database size compare with Rephonic and ListenNotes?
- PodPitch states its index is larger than Rephonic, ListenNotes, and Podcast Index, at 3.85M+ podcasts with verified host emails. The sources reviewed for this site did not list a total show count for those rivals, so our comparison table marks their size as not stated. Rephonic's published plans are framed around searches and campaigns rather than a headline index size.
- How often do other podcast databases update?
- It varies, and many vendors do not publish a cadence. The sources reviewed for this site stated a daily refresh for PodPitch and no refresh interval for Rephonic, ListenNotes, Podchaser, or Podseeker. Before buying any database, ask how often contacts are re-verified and how quickly dormant shows are removed, then test with a small send.
- What features should I compare in podcast outreach software?
- Compare six things: database size and coverage, how often contacts are refreshed, whether emails are deliverability checked, how pitches are personalized, whether sending and follow-ups run from your own inbox, and how replies and bookings are tracked and reported. Also check seat limits, search limits, and contract terms, since entry plans often cap users and searches.
- Where does PodPitch's podcast data come from?
- PodPitch scans Apple Podcasts, Spotify, and dozens of other sources every 24 hours to capture new shows, new episodes, and contact changes, then combines them in what it calls the PodPitch Algorithm. Titles and descriptions come from what hosts enter on Apple Podcasts and Spotify, while topics, listener estimates, and scores are generated by PodPitch's AI from episode content.
- Can I see a sample PodPitch podcast profile?
- Yes. PodPitch publishes public profiles such as podpitch.com/podcasts/new-generation-mindset, showing category, publishing frequency, episode count, latest episodes, an audience band, a reply rate band, and a pitch volume rank. Each profile shows the date its data was updated. Exact listener estimates and verified contact fields are unlocked in a demo or account.
