How to Grow a Podcast: The Levers That Actually Work

Most advice on how to grow a podcast falls into two camps: the obvious ('make great episodes') and the useless ('post more on social'). Neither explains why your show climbed to a few hundred listeners and then stopped moving. This guide does. It ranks the growth levers that genuinely shift the numbers, explains why consistency embarrasses every hack, and finishes with a 90-day plan you can actually run.

Earworm makes video podcasts for B2B brands like Soldo, IG Group and Cisco, so the examples lean B2B, though the principles hold for most shows. And if you would rather have specialists run the whole system for you, that is exactly what our podcast growth service is for.

Why most podcasts plateau

Podcast apps are terrible at discovery. Apple Podcasts and Spotify recommend very little, the charts reward launch spikes rather than quality, and there is no feed of strangers waiting to stumble across your show. A blog post can rank on Google for years. A YouTube video gets recommended indefinitely. An audio episode sits in a feed, visible mostly to people who already subscribe.

So the typical growth curve looks like this: you launch, your network listens, the numbers climb for a couple of months, then everything flattens. The plateau is not a quality problem. It is a distribution problem. Your show has saturated the audience you already had, and publishing new episodes does nothing on its own to reach anyone new.

The fix is to treat each episode as raw material for distribution rather than the finished product. The levers below are how you do that, ranked by how much they actually move listener numbers.

How to grow a podcast: the growth levers, ranked honestly

1. Guest audiences (the biggest lever)

The most reliable way to grow a B2B podcast is to borrow other people's audiences, and guests are the cleanest way to do it. Every guest with a genuine following is a distribution channel. Book twenty of them a year and you have twenty warm introductions to twenty relevant audiences.

Two rules make this work. First, book guests for their audience as well as their expertise. A brilliant operator with no public presence makes a lovely episode and adds zero reach; you want insight and reach together. Second, make sharing effortless. Send every guest their own captioned clips and a suggested post on the day the episode goes live. A guest who shares one strong clip with an audience of thousands does more for your show than a month of your own posting.

There is a useful side effect in B2B. The right guest is often also a prospect, a partner or a referrer, and an hour of genuinely good conversation opens doors that cold outreach never will. Even when an episode does little for your audience numbers, the relationship alone can justify the recording. Growth and pipeline are not separate goals here; a good guest list serves both.

2. Clips on LinkedIn and YouTube Shorts

Here is the honest version: clips rarely convert viewers into subscribers at a rate that will impress you, and anyone claiming otherwise is selling something. What clips do brilliantly is build familiarity at scale. Most of your future audience will never browse a podcast app looking for you. They will see a sharp 60-second moment in their feed, then another a week later, and eventually go looking for the show behind them.

For B2B, LinkedIn comes first, because that is where your buyers already scroll. YouTube Shorts comes second, because Shorts feed the same channel where your full episodes live and the algorithm quietly connects the two. Treat clips as advertising paid for in editing time rather than money, and judge them on reach and engagement rather than direct subscriber attribution, because you will almost never see the attribution.

3. YouTube as a search channel

YouTube is a search engine with a recommendation engine bolted on, which makes it everything podcast apps are not. Publish full video episodes with titles based on what people actually search, not clever wordplay. 'How finance leaders build a hiring plan' will be found. 'Episode 47: a chat with Sarah' will not.

Two things happen when you do this properly. Your episodes keep collecting viewers months after release, because search does not care about your publish date. And YouTube actively pushes your content to people who have never heard of you, which no podcast app will ever do. If you add only one distribution surface this year, make it this one.

4. SEO for your show pages

Every episode deserves a page on your own site with a descriptive title, proper show notes and ideally a transcript. Each page is a chance to rank for the specific questions that episode answers. No single page will flood you with listeners, but thirty of them quietly gathering search traffic adds up, and unlike social posts they do not expire.

This lever is slow and unglamorous, which is precisely why your competitors will not bother. Start early. The compounding is the point.

5. Cross-promotion with other shows

Podcast listeners are the hardest audience to find anywhere except inside other podcasts. So go there. Get your host booked as a guest on adjacent shows, arrange promo swaps where each show trails the other, and consider feed drops with shows that share your audience.

The ask scales with your size, so small shows swap with small shows. That is fine. A hundred listeners who arrive from another podcast already like the format, already have an app installed and already finish what they start. They are worth many times their number in cold social impressions.

6. Paid promotion (occasionally, deliberately)

Paid sits last because it is a multiplier, not an engine. It works in three situations: building launch velocity, amplifying clips that already perform organically, and precise B2B targeting where a single listener could be worth a serious contract. Outside those cases it is an expensive way to rent listeners who do not stay.

One rule: never pay to promote a show people do not finish. Fix completion first, then buy attention.

Consistency beats hacks

The uncomfortable truth about how to grow a podcast is that the biggest variable is still being there in a year. Podfade is real. Most shows quietly stop long before their audience has had a chance to find them, which means the bar for outlasting your competition is embarrassingly low.

Every lever in this guide compounds. Guests introduce the next guests. YouTube's back catalogue keeps earning views. Search rankings build. Cross-promotion relationships deepen. None of it works in bursts, and all of it resets when you disappear for two months.

So pick a cadence you can sustain on your worst month, not your best. Fortnightly for two years beats weekly for six months, every time. And be suspicious of anything marketed as a growth hack. If it worked at scale, it would already be a category on this list.

Consistency covers format as much as frequency. Audiences follow a show because they know what they will get: the same structure, a similar length, a recognisable point of view. Experiment inside the format rather than with it, and change one thing at a time so you can tell what actually worked.

The video multiplier: one recording, many surfaces

Everything above gets dramatically easier when you record on video. One filmed conversation becomes a full YouTube episode, an audio episode for Apple and Spotify, a handful of LinkedIn clips, YouTube Shorts, quote posts and a searchable show notes page. One hour in the studio, weeks of distribution.

This is why Earworm is video-first. Every recording our clients make becomes YouTube episodes, LinkedIn clips and audio feeds as standard, because running the levers above without video means fighting with one hand tied behind your back. If your show is still audio only, moving to video podcast production is the single upgrade that unlocks most of this list.

What to measure (podcast audience growth is not downloads)

Downloads are the industry's default metric and its least useful one. A download is a file transfer, not a listen, and it tells you nothing about who was listening. Real podcast audience growth shows up across several numbers:

• Completion rate. The best proxy for quality you have. If people finish episodes, everything else is fixable.
• Followers per platform. Spotify and Apple followers, YouTube subscribers. This is your recurring audience, and it deserves tracking surface by surface.
• YouTube watch time and impressions. These tell you whether the algorithm is working for you or ignoring you.
• Clip reach and engagement on LinkedIn. Your familiarity engine. Watch the trend across weeks, not individual posts.
• Show page traffic. Evidence the SEO lever is turning.
• Business outcomes. Guests who became customers, deals that mention the show, inbound from listeners. For a B2B show, this is the score that matters.

That last point deserves emphasis. A show about life insurance, like Pretty Covered, which we make for Polly, is never going to trouble the comedy charts, and it does not need to. Five hundred of exactly the right listeners beats fifty thousand of the wrong ones. It is also why the Report stage of our process covers pipeline attribution rather than stopping at audience charts.

A realistic 90-day podcast growth plan

Ninety days will not take you from two hundred listeners to twenty thousand, and anyone promising that is lying to you. What ninety days can do is replace a plateau with a slope. Here is the sketch.

Days 1 to 14: fix the foundations

• Write down who the show is for, in one sentence. Every decision below refers back to it.
• Record your baseline: completion rate, followers per platform, YouTube stats, show page traffic.
• Rewrite episode titles so they say what each episode is about. Search first, wordplay second.
• Set up, or tidy up, your YouTube channel and your episode pages.

Days 15 to 45: build the engine

• Book six to eight guests who bring both insight and an audience.
• Start a clip system: at least three captioned clips per episode on LinkedIn, plus Shorts.
• Publish full episodes to YouTube with searchable titles and decent thumbnails.
• Send every guest a share kit (their clips, a suggested post) on release day.

Days 46 to 75: add fuel

• Pitch your host as a guest on three to five adjacent shows.
• Arrange one promo swap with a show that shares your audience.
• Double down on whichever clip formats are outperforming the rest.
• Add transcripts and proper notes to your best back-catalogue episodes.

Days 76 to 90: review and reinvest

• Compare everything against your baseline. Judge trends, not single spikes.
• Kill the tactics that produced nothing and keep the ones that are compounding.
• If completion rates are strong, consider a small paid test. If not, fix the show first.
• Plan the next quarter around the cadence you actually sustained, not the one you intended.
