The Booking Probability Index

Most podcast databases tell you how big a show is. Very few tell you the thing that actually matters before you pitch: how likely it is to book a guest at all. Booking Probability is our attempt to measure exactly that, across a catalog of more than 850,000 shows.

What the number means

Booking Probability is a score from 1 to 99 that estimates how likely a given show is to say yes to a guest pitch. It is not audience size and it is not a quality rating. A large, prestigious show can have a low Booking Probability because it rarely takes outside guests, while a mid-sized show that interviews someone new every week can score high. The score answers a booker's real question: is it worth spending a pitch here.

How it is built

The index sits on top of two layers. The first is Pod Score, which reads a show's audience, publishing recency, cadence, and host signals. The second is Booking Probability itself, which weighs how open the show is to guests: whether it features interviews at all, how often, how recently, and how reachable the person who books guests is. Every show in the catalog is scored the same way and refreshed continuously, so the index reflects the landscape as it is now, not as it was when someone last updated a spreadsheet. The full scoring method is published on our methodology page.

How to read it before you pitch

Use it as a filter, not a verdict. A high score means the show books guests like clockwork, so your effort is well spent; a low score means you will need a warmer angle or a personal connection to break in. Sorting your target list by Booking Probability is the single fastest way to stop wasting pitches on shows that were never going to say yes.

The current top shows by Booking Probability, updated continuously, live on the index itself. The numbers move as shows publish, change cadence, or open and close to guests, so we keep them on a live page rather than freezing them here.
