Rather than guessing why a show isn't growing, Chris Hutchins buys a small, cheap podcast-app ad (e.g. on Overcast) and reads two separate metrics as a diagnostic: click-through rate reveals whether the packaging (cover art, title, description) is working, and post-tap subscribe rate reveals whether the actual content is working. You can even run it against a trailer before recording a full show.
Origin
Chris Hutchins' experiments running dynamic-priced ads in the Overcast podcast app.
Core principles
- 01Packaging and content are separate failure points and must be measured separately.
- 02Click-through rate is a clean test of packaging: art, title, and description.
- 03Subscribe rate among people who already tapped isolates content quality.
- 04A few hundred dollars buys a diagnostic you can run before even producing the show.
How to run it
- 1
Buy a small, well-timed ad
Run a cheap ad in a podcast app like Overcast, watching the dynamic pricing for a low-demand week (the same slot can swing from ~$200 to ~$700).
Pro tip Prices fluctuate by category demand week to week — wait for a cheap window before buying.
Watch out Paid acquisition typically costs ~$3-$10 per podcast listener, so this is a diagnostic, not a scalable growth channel early on.

Read click-through rate as a packaging test
Compare your click-through rate to the platform's benchmark. If you're supposed to get ~2% and get ~0.5%, the topic, description, or cover art is the problem.
Pro tip A weak click-through isolates the failure to packaging — fix art/title/description before touching content.
Watch out Low CTR means people never even reached your content, so don't blame the episodes yet.

Read subscribe rate as a content test
Of the people who tapped, see how many subscribed versus the benchmark. If the benchmark predicts ~50 subscribers per 1,000 taps and you get 7, the content (trailer/episode) is the problem, not the packaging.
Pro tip These are people who read the description and were interested — their failure to subscribe points squarely at content.
Watch out Don't conflate the two funnels: a good CTR with a poor subscribe rate is a content problem masquerading as a growth problem.

Test before you fully build
Run the ad against just a trailer before recording a full season to validate packaging and appeal cheaply.
Pro tip You can even A/B two different descriptions for the same show to see which packaging converts.
In the wild
Across his Overcast experiments Chris spent roughly $1,000 and garnered hundreds (not thousands) of subscribers. He treats the two numbers separately: a low click-through means the topic/description/cover is weak, while a healthy click-through but low subscribe rate means people sampled the content and passed.
→ For a few hundred dollars he can localize the growth bottleneck to packaging vs content instead of guessing — and can run it on a trailer before producing a full show.
Common mistakes
Treating cheap ads as a scaling channel
At ~$3-$10 per listener the economics rarely justify paid growth early; using ads to buy audience rather than to diagnose the funnel burns money without insight.
Reading only one number
Looking at subscribers alone conflates two distinct failures — if you don't separate click-through (packaging) from subscribe rate (content), you'll 'fix' the wrong thing.
Is it for you?
Best for
A podcaster trying to diagnose why a show isn't growing, or validate packaging and appeal before investing in full production.
Not ideal for
A creator looking for a scalable, positive-ROI acquisition channel — the per-listener cost usually doesn't pencil out early.
From the transcript
“if you're supposed to get like a two percent click-through rate and you get 0.5 then it's like actually the topic or the way I…”
“that means my content probably sucks like that means someone listened to a trailer or an episode or something more than the description”
