Potential listeners who have never opened your feed, existing listeners who forget to press follow, and the guests and sponsors watching from the sidelines.
Podcasting has a discovery problem that no other medium has. There is no feed inside a podcast app that surfaces you to strangers, no autoplay from someone else's episode, and no algorithm doing the introductions. Instagram is where most shows actually get found, which means your grid is doing work your app store listing never will.
The default answer to that — a waveform, a quote card, a photo of two people in headphones — fails because it tells nobody what the episode is about or why to press play today. The account has to sell a specific twelve minutes, not a show in general, and it has to do it to people who have never listened to any podcast at all.
The ideas below are built around the two numbers that decide whether a show survives: how many strangers press follow, and how many of them come back for the next episode. Each gives you the first slide, the sequence, and a caption starter, so a release week has something to post besides "new episode out now".
What actually performs for podcasts
Selling one moment, not the episode. "The bit at 14:20 where he admits he was wrong" converts, because it promises something specific rather than forty minutes of unknown quality.
Asking explicitly for the follow. Most listeners stream episodes without ever pressing follow, and a post that explains the difference does more for retention than a month of clips.
Publishing your own numbers — downloads, completion rate, the week things dropped. It flatters the listeners who are already there and gives the show a story between episodes.
Onboarding people who have never used a podcast app. A large part of any Instagram audience does not listen to podcasts at all, and a ninety-second how-to converts more of them than any trailer.
A curated entry point into the back catalog. New listeners open episode ninety-four, hear a running joke they don't understand, and leave. Telling them where to start rescues the archive.

One 40-minute episode takes eleven hours to make

2/6
Research and guest prep: three hours, minimum.
3/6
Recording: ninety minutes, plus setup and small talk.
4/6
Editing: four hours. Most of it removing ums and silence.
5/6
Show notes, chapters, artwork, uploads: another two.
6/6
Eleven hours, every week, for something that's free.
Caption starter
Not a complaint, just the honest arithmetic behind a weekly show. If you want to make the eleven hours worthwhile, press follow in whichever app you use.
Why it works: Revealing the effort behind a free product creates reciprocity, which is what converts passive listeners into followers and supporters.
Streaming an episode does nothing for the show's numbers.
3/6
Following means the next one downloads automatically.
4/6
It also tells the app that people want this show.
5/6
It's free, it's one tap, and it changes everything.
6/6
Open your app, find the show, press follow. That's it.
Caption starter
The single most useful thing a listener can do, and most people have never done it because nobody asked. One tap in whatever app you use. That's the whole request.
Why it works: Followers receive every new episode automatically, so converting streamers into followers does more for retention than anything else a show can ask for.
Eleven minutes of the guest and me finding a rhythm.
3/6
Nine minutes of a story that went nowhere. It happens.
4/6
Six minutes of a tangent I'll use in a bonus episode.
5/6
The rest is ums, silences and one very loud truck.
6/6
The edit is the show. The recording is the raw material.
Caption starter
The version you hear is less than half of what was said in the room. Editing is where a conversation becomes an episode. This week's is up now, forty-two minutes.
Why it works: Showing the cutting-room floor signals quality control and reassures new listeners that their time is being protected.

Your phone already has one. Apple Podcasts or Spotify.
3/6
Search the show name. It's spelled exactly like this.
4/6
Press follow. New episodes then arrive on their own.
5/6
Download over wifi if you're going somewhere without signal.
6/6
That's the whole thing. No account, no payment, no ads required.
Caption starter
Written for everyone who's said they'd listen but has never opened a podcast app. It takes ninety seconds and there's nothing to sign up to. Send it to whoever needs it.
Why it works: A large share of any Instagram audience has never listened to a podcast, and removing that friction unlocks listeners no clip could reach.
No two-minute intro music. Nobody has ever waited through it.
3/6
Open with the best twenty seconds from the middle.
4/6
Then say what the episode is and who's on it.
5/6
Housekeeping goes at the end, if anywhere.
6/6
We rebuilt every episode around this and retention moved.
Caption starter
The structure change that made the biggest difference to this show. Cold open, then the framing, then the conversation. Music at the front is a habit, not a rule.
Why it works: It teaches a craft lesson that other podcasters share, while implicitly promising new listeners the show respects their time.

A night nurse in Tulsa, on the drive home.

A man who paints bridges. Two hours a day, alone.
4/6
Someone in a tent in Patagonia, downloaded in advance.
5/6
A woman who listens to the same episode every Sunday.
6/6
Tell me where you listen. I read all of them.
Caption starter
The listener messages are the best part of this. Nobody sits and stares at a podcast, and knowing where you actually are changes how I make it. Tell me yours.
Why it works: Listener stories generate comments and DMs while showing new people the show fits into a real part of the day.
“How podcast ads are priced, and why we have none”

2/6
Advertisers pay per thousand downloads, not per episode.
3/6
A host-read mid-roll usually lands between $18 and $25 per thousand.
4/6
So a 2,000-download show earns about $40 an episode.
5/6
That's why small shows can't live on advertising.
6/6
We'd rather ask 200 of you for $4 than run ads.
Caption starter
The economics nobody explains. Advertising only works at scale, and this show isn't at that scale. Membership is the alternative and it costs four dollars a month.
Why it works: Explaining why advertising is not viable makes a membership ask feel like a reasoned choice rather than a plea.
A twenty-minute pre-call first. No recording, no questions sent.
4/6
If they want the questions in advance, it usually won't work.
5/6
Recorded four to six weeks before it goes out.
6/6
Publicists pitch me daily. Almost none have actually listened.
Caption starter
The booking process, including the ratio, because people assume guests just appear. If you're pitching a show, listening to one episode first puts you ahead of nearly everybody.
Why it works: It positions the show as selective and quietly instructs the PR audience on how to pitch properly.

2/6
The industry standard counts one device once in 24 hours.
3/6
It also requires at least sixty seconds of the file.
4/6
It still can't tell you whether anyone heard minute thirty.
5/6
Completion rate is the number that actually matters.
6/6
Any show quoting only downloads is choosing the kinder number.
Caption starter
Useful if you're buying podcast advertising or comparing shows. Downloads measure delivery, not attention. Ask any show for its completion rate instead.
Why it works: Correcting a metric that sponsors and other podcasters misuse establishes authority and is heavily shared within the industry.
“Ninety-four episodes in. Here are the four to start with.”

Ninety-four episodes in. Here are the four to start with.

2/6
Episode 12 if you want to know what the show is.
3/6
Episode 38 if you want the best guest we've had.
4/6
Episode 61 if you like an argument.
5/6
Episode 90 if you want us at our current best.
6/6
Then go anywhere. Nothing depends on order.
Caption starter
New listeners always start with the most recent one, which is rarely the best introduction. These four are. Save this and pick whichever sounds like you.
Why it works: A curated entry point rescues the back catalog, which is where most of a mature show's ongoing downloads come from.
Hosting, editing and music cost money every month.
3/6
One sixty-second read covers about a third of it.
4/6
We only take sponsors we'd mention anyway. Two so far declined.
5/6
Members get the same episode with the ad removed.
6/6
If the ad bothers you, membership is the fix. Four dollars.
Caption starter
Occasionally asked, usually politely. Here's what the show costs to run and where the sponsor money goes. Members get an ad-free version of the same feed.
Why it works: Addressing the advertising objection openly converts irritation into memberships and pre-empts negative reviews.
Anything about the show, the guests, or the subject.
3/6
Last time we got 63 questions and answered 21.
4/6
The most asked one was about the guest we never got.
5/6
Anonymous is fine. Voice notes are better.
6/6
Comments or DMs, until Sunday night.
Caption starter
Recording the listener questions episode on Monday. Send a voice note if you can, because hearing your actual voice on the show is much better than me reading it out.
Why it works: Voice notes convert a scroll into audio participation, and every contributor listens to the episode to hear themselves.

The guest cried. I didn't know what to do with it.
3/6
It sat unedited for three weeks while I decided.
4/6
I asked her. She said publish it, so we did.
5/6
It's still the most listened-to episode we've made.
6/6
Ask first. Then trust that people can handle honesty.
Caption starter
The hardest editorial decision I've had to make and the one I'd make the same way again. Episode six, if you've never heard it.
Why it works: A story about editorial judgment builds trust with both listeners and future guests, who are deciding whether you can be trusted with their words.
Charts reward a burst of new followers, not total size.
4/6
Which means it was all of you, in one afternoon.
5/6
Two guests have since said yes because they saw it.
6/6
Thank you. It genuinely changes who agrees to come on.
Caption starter
Six hours at number four, entirely because a few hundred of you followed in the same afternoon. It has already changed who says yes to an invitation. Thank you.
Why it works: Chart placement is credible proof for prospective guests and sponsors, and crediting listeners for it encourages them to do it again.
A rug on the floor, because hard floors echo badly.
4/6
Foam on one wall only. The reflective one.
5/6
Microphone four inches away, off to the side.
6/6
That's it. No studio, no booth, no soundproofing.
Caption starter
People assume there's a studio, and there's a spare room with a blanket over the window. The physics of a soft room does most of the work. Ask me anything about the setup.
Why it works: Demystifying the production makes the show feel handmade and gives the podcaster audience a practical reason to save the post.
Most listening happens on a commute. Commutes stop in August.
3/6
Every show's numbers fall. Nobody's doing anything wrong.
4/6
So August here is the archive month. Two rereleases.
5/6
Plus one long episode built for a road trip.
6/6
Download before you travel. Signal is optimistic on the interstate.
Caption starter
The annual summer dip that makes every podcaster nervous. Commuting drives listening and nobody's commuting. Download the long one before you drive anywhere.
Why it works: Naming a predictable seasonal pattern reframes a downturn as normal and creates a reason to promote the back catalog.
Tell me the argument you'd make, not your job title.
4/6
It has to be something you can't say elsewhere easily.
5/6
No promotional book tours unless the book is genuinely good.
6/6
Three lines is enough. Send it to the email on the profile.
Caption starter
I get pitched most days and almost none of them mention an actual episode. Three lines, one argument, and evidence you've listened. That's all it takes.
Why it works: Publishing guest criteria improves the quality of inbound pitches and signals to listeners that the booking is curated.
"In March 2019 I was sitting in a parking lot" works.
4/6
"I've always believed that" does not.
5/6
Detail is what makes something audible in someone's head.
6/6
It's the whole difference between a talk and a conversation.
Caption starter
Advice I give every guest before we record, and it works in any interview. Start with a scene, not a summary. Useful whether you're on a podcast or in a job interview.
Why it works: Craft advice that transfers outside podcasting reaches a wider audience while demonstrating the interviewing standard of the show.
Check your feed in every app after any change. Every time.
Caption starter
Posting this in case it saves another show four days. A broken feed looks exactly like a failing show in the analytics. Check every app after any change.
Why it works: A candid problem-solving story builds trust with the peer audience and is the kind of specific post that gets bookmarked and cited.
Three posts per episode week: one timestamped pitch on release day, one clip or behind-the-scenes mid-week, and one educational or archive post at the weekend. Write all three while the episode is still fresh in the edit.
Hashtags for podcasts
Mix these with location tags for your own area. Put them in the first comment so the caption stays readable.
