Which Podcast Niches Actually Book Guests?

The same three checks, across 16 topics

Every readable feed in the directory, grouped by the topic we file it under, ordered by the measure most people would rank on. Read the "books guests" figures down first, then the "passes all three" ones.

Two things happen between "books guests" and "passes all three". The spread shrinks: 41 points of difference between the best and worst topic on guest evidence becomes 24 points on the conjunction. And the order stops holding. Startups leads on guest evidence at 58% and finishes 2nd on the conjunction. Leadership sits 2nd on guest evidence at 48% and lands 15th of 16 once the other two checks are applied. 9 of the 16 topics move at least 3 places between the two orderings.

The "network-run" column is there for a different question, and it is worth reading on its own terms rather than against the others. Topics differ in who makes the shows in them: 57% of the Business shows we read are published by a network, a studio or a media brand, against 0% in Sobriety & Recovery. That is a fact about who you will be writing to, not about whether they say yes. Build a list in Business and 57% of it has a booking desk somewhere between you and the host; build one in Sobriety & Recovery and 100% of it is a person with their own inbox. Those are two different pitches, and this column tells you which one you are writing before you write it.

It does not explain the column next to it, and the numbers say so plainly. Across topics the network share spans 57 points. Across individual shows, where the comparison is like for like, network-run shows publish visible guest evidence 27% of the time and independents 32%, 5 points in favour of the independents. A difference that small cannot be what produces a 41-point spread between topics, so do not read the two columns as one finding.

The same split run through all three checks, with what the label is and is not worth to a guest, is our network-versus-independent comparison. It reads the same 362 feeds the table above reads, sorted by who publishes the show instead of by what it is about.

The topics that advertise guests are the topics that stop publishing

The two measures are not independent, and they run against each other. Sort the topics by guest evidence and take the top half: 41% of those 181 shows publish visible evidence they book guests, against 22% of the 181 in the bottom half. That is the gap you were going to act on, and it is real. Now look at the "still publishing" figures for the same two groups: 73% of the guest-friendly half was still publishing when we read it, against 80% of the other half.

That is not a coincidence of our sample, it is what those topics are. The shows that talk about founding a company, growing an audience or changing your life are made by people whose subject is a thing they are currently doing, and they are made in enormous numbers by people trying it for the first time. Shows about a body of knowledge that exists whether or not the host is having a good year behave differently: fewer of them advertise a guest chair, and far more of them are still there a year later.

So the guest-friendly half does still finish ahead on the conjunction, 25% against 17%. But the advantage is 8 points rather than the 19 it looked like, because roughly half of it is spent on shows that had already stopped. You are not choosing between topics that book guests and topics that do not. You are choosing between topics where more shows say yes and fewer are still open, and topics where the reverse is true.

What the best topic in this table is actually worth

Take the winner on its own terms. Marketing is the strongest topic here on all three checks together: 8 of its 24 shows passed, 33%. The weakest is Nutrition at 9%. That difference is worth knowing and it is the honest reason to read this table.

It is also worth less than it sounds, because the winning topic still fails you roughly 11 times in 16. Whichever corner you aim at, most of the shows in it will be quiet, unreachable, or silent about whether they book anybody. Choosing the best topic in this table moves your hit rate by 24 points. Checking the individual shows takes you to a list where every one of them passes, because the checks are the filter and the topic is only a prior.

And the topic is usually not yours to choose anyway. You can talk about what you have done. A Nutrition expert pitching Marketing shows is a worse guest than a Nutrition expert pitching Nutrition shows, and the table above is nowhere near lopsided enough to argue with that. Use it to set your expectations for how many shows you will need to look at, not to pick a subject you cannot speak on.

How to use a topic ranking without being misled by it

Concretely:

• Start from what you can credibly talk about, then use this table to size the list. In the strongest topic here, 33% of shows passed all three checks; in the weakest, 9%. Either way you are reading a lot of feeds.
• Never rank topics on the guest-evidence column alone. It is the column with the 41-point spread and it is the one most contaminated by shows that have stopped, which is why the order changes when you check.
• If your subject sits in one of the topics near the top of the guest-evidence column, add the liveness check first rather than last. That half of the corpus was only 73% live, so the shows you find by searching will disproportionately be shows that already ended.
• If your subject sits near the bottom, stop treating that as bad news. Those topics were 80% live, their shows are markedly easier to still be there when you write, and almost nobody pitching by category is bothering with them.
• Cross the topic with a second property rather than stopping at it. Catalogue size and network ownership both move the odds more reliably than topic does, and we publish what each of them is worth.

The summary in one line: topic is a prior, not a filter. Between the best and worst corner of this directory it is worth 24 points of hit rate, which is real and is smaller than the checks that come after it.
