How to create a 30-second podcast ad (with word counts and structure)
When we talk to advertisers at Acast, they often ask us how to craft the perfect podcast message. A 30-second podcast ad is about 70 to 80 words spoken at a natural pace of 150 to 160 words per minute. It is the workhorse of podcast advertising. It is long enough to land one clear idea and a call to action, yet short enough that a listener will not skip it.
We know that listener attention is incredibly high, with 64% of people stating they give podcasts their full attention. Here is exactly how you can write, time, and produce an effective spot that turns that attention into action.
How long is a 30-second podcast ad in words?
Aim for 70 to 80 words. Then read it aloud with a stopwatch, because delivery pace matters more than any word count rule. A conversational host-read runs slower than a tightly produced spot, so the same 30 seconds might hold 65 words in one voice and 85 in another.
Writing for a few lengths at once? A rough guide:
- 15 seconds is about 40 words.
- 30 seconds is 70 to 80 words.
- 60 seconds is 140 to 160 words.
Time it. Do not trust the word count alone.
Why 30 seconds is the format to master first
More than half of podcast ads now run 16 to 30 seconds, up from 38% of inventory in 2019. Creative testing keeps landing on the same finding, which is that 30-second ads perform well across nearly every objective, from awareness to direct response. If you build one spot, build this one.
A 60-second spot still earns its place when you need to explain a product in depth. For a single message and a clear action, 30 seconds does the job without wasting the listener's attention or your budget.
The structure of a 30-second ad that converts
You have roughly four beats. Use them on purpose.
- Hook (zero to five seconds): Open with the problem or a specific, surprising line. Do not use your brand name yet. The listener has not decided to care yet.
- Value (five to 18 seconds): Give one benefit, made concrete. Resist listing three. A 30-second ad that tries to say everything says nothing.
- Proof (18 to 24 seconds): Give a number, a detail, or a reason to believe you.
- Call to action (24 to 30 seconds): Give one action, said twice. Repeat the promo code or the URL. Podcast audiences love a dedicated offer, and 40% of listeners have used a promo code they heard on a podcast. Listeners are usually doing something else while they tune in, so repetition is key.
Host-read or pre-produced targeted ad: decide before you write
The format changes how you write. A host-read ad is a brief, not a script. You give the host the key message, the proof points, and the legal lines they cannot change, then let them say it their way.That is why host-read works. In fact, host-read ads convert 37% better than announcer-read ads. In one study, 68% of listeners retained 80% or more of a host-read ad, compared with 50% for a standard produced spot. Furthermore, sponsorships drive up to 71% higher brand recall.
A produced spot using targeted ads is fully scripted and voiced, which buys you control and consistency across shows. Weighing the two? See our guides to host-read sponsorships vs Targeted Ads and which podcast advertising format to choose.

Frequently asked questions
How do I create a 30-second podcast ad?
Write a 70 to 80 word script built around one benefit and one call to action, time it by reading aloud, then record it as a host-read brief or a produced spot. On Acast's ad platform you can generate a finished 30-second ad from a prompt using the built-in AI audio tool, choosing voice, tone, and music, then run it across 140,000+ shows.
How long should a podcast ad be?
Most podcast ads run 30 or 60 seconds. Thirty seconds is the most common and the most versatile, performing well for both awareness and direct response. Choose 60 seconds when you need to explain a product in detail, and 15 seconds for simple reminders or retargeting.
How many words is a 30-second podcast ad?
About 70 to 80 words at a natural speaking pace. Always confirm by timing your script aloud, since a relaxed host-read fits fewer words than a tightly produced read.
What makes a 30-second podcast ad effective?
One clear message, a strong opening line, proof the listener can believe, and a call to action repeated twice.
