Podtrac

Podtrac is the podcast measurement OG — founded in 2005 and the default name media kits cite when describing audience reach. The free measurement service adds a prefix to your RSS feed, then publishes monthly Industry Audience Rankings that ad buyers and PR teams actually read.

Inclusion is automatic for any show using the Podtrac prefix, and the rankings are IAB-compliant. For shows pitching national sponsors, having a Podtrac number is table stakes. The free tier covers basic measurement and demographic surveys; a $20/mo Grow Your Show plan unlocks historical data, Smartlinks, and platform-by-platform tracking.

Where it shines is trust and legitimacy — Podtrac numbers carry weight in advertiser conversations in a way newer or proprietary metrics don't, particularly for big-tent shows aiming for the top of rankings. Where it falls short is everything modern analytics platforms have built since: no attribution, light demographics, no marketing tooling, no integrations, and a dashboard that frankly looks 15 years old.

You won't run growth experiments here or figure out which social channel drove your spike. Treat Podtrac as your sponsor-facing certification layer — the public scoreboard — and pair it with OP3 for transparency, CoHost or Magellan for attribution, and Voxalyze or Chartable for discovery analytics.

As one tool in the stack, it's essential. As the only one, it's a relic.
