Radio & audio advertising: streaming, podcast and frequency
Radio, streaming audio and podcasts in 2026: the formats, how they're bought and how they're really measured. Frequency and presence in screen-free moments.
MEDIA · CHANNELS · RADIO & AUDIO
In · Listening without a screen
Out · Presence in screen-free moments
Broadcast radio · FM/DAB+
FM and DAB+ radio and its streams via app and smart speaker. Broad, habitual reach, dominant in the car and in the morning: bought by spot, by station and daypart, measured on listening, reach and time spent listening.
Streaming audio
Ad-supported music and news platforms. The ad enters between content with targeting by profile, context and moment: it brings precision and a companion display where the ear doesn't click.
Podcast · host-read
On-demand content tied to the voice that hosts it. The home of host-read: maximum trust and depth of listening, delivery often via dynamic insertion at the moment of play.
Dynamic ad insertion (DAI)
The technology that decides which ad to insert at the moment of listening: one plan, many versions for city, daypart, context. It turns streaming and podcast into spaces as targetable as digital.
Programmatic audio
Automated buying of audio, in private deals or open auction, by data and context. Same logic as the rest of programmatic: the same pre-bid rules on quality, context, price and frequency apply.
The medium that gets in without a screen
Radio, streaming audio and podcasts are the same good bought three ways: the attention of someone doing something else. Driving, cooking, running, working. It's the one channel that works when the eyes are busy.
Broadcast radio
FM and DAB+, plus the same streams via app and smart speaker. Broad, habitual reach, strongest in the car and in morning dayparts: bought by spot, by station and by daypart.
Streaming audio
Ad-supported music and news platforms. The ad slots between tracks or in the stream, with targeting by profile, listening context and time of day.
Podcast
On-demand content with a strong bond to the voice that hosts it. This is where host-read lives: the ad read by the person the listener trusts, felt as a recommendation more than a spot.
The common thread
No image, no immediate click: only voice, context and repetition. That's why audio builds frequency and memory, not cold-start response.
What you can actually put on air
There isn't one spot. Production, tone and the way the listener receives them all change.
Produced spot
The classic 15-30 seconds crafted by the brand: full control of voice, music and message. Works for reach and recall, identical on every station or stream.
Host-read / read in voice
Delivered by whoever fronts the show, in their own language. Maximum trust and context, but less control over wording: you steer with a brief, not a locked script.
Sponsorship and branded segment
The brand tied to a feature, a weather slot, a chart. Continuous presence and ownership of a moment, more than a single airing.
Digital audio spot + companion
The ad in streaming or podcast, often with a companion banner in the app that brings back the click audio lacks. Targetable and measurable like the rest of digital.
Dynamic audio (DAI)
The same slot serves different creative to different people, decided at playback: city, daypart, weather, sequence. One plan, many versions.
Four routes to the same listening
Audio is bought in ways that coexist in the same plan. The choice depends on what you're after: reach, context or precision.
Space booked by daypart, programme or package. This is the broadcast way: you negotiate reach and placement, you pay per airing or by rate card.
For host-read and content ownership: agreed with the show or network, often with category exclusivity and an editorial bond a volume buy can't give.
Catalogues aggregating many podcasts and streams: bought on a CPM against segments and genres, with the ad delivered via DAI at the moment of play.
Automated buying, in private deals or open auction, targeted by data and context. Same logic as the rest of programmatic: the same pre-bid rules on quality and frequency apply.
Broadcast and sponsorship are booked ahead; marketplaces and programmatic activate and retune within the day.
From reach to real effect
Audio doesn't hand you the click like display. It's measured on two planes: how many people it reached, and how far it moved them. You need both.
| What you measure | Metric / method | What it actually tells you |
|---|---|---|
| Broadcast reach | Measured listening: average audience, net reach, time spent listening | How many people could hear it and for how long — not whether they acted |
| Pressure and repetition | Average frequency and contact distribution | Whether you're building memory or just saturating the same few |
| Share of listening | Share of ear across broadcast, streaming and podcast | Where your audience's listening time actually moves |
| Digital response | Conversion pixels, dedicated URLs and codes, post-exposure visits | How many online actions follow the listen — visible mostly on streaming and podcast |
| Brand effect | Brand lift: recall, consideration, intent on exposed vs unexposed | Whether audio shifted perception, not just the last click |
| Net contribution | Cross-media incrementality and dedup of reach and frequency | How much value audio adds next to other media, without double-counting |
Where audio pays and where it burns budget
It isn't a universal medium. It pays when you use it for what it's good at; it wastes when you ask it to do another channel's job.
- It pays when you need frequency and presence. Screen-free moments, habitual listening, repetition that builds memory: audio does what display can't.
- It pays when the voice matters. Host-read and sponsorship transfer trust: the listener feels a recommendation, not an interruption.
- It wastes if you treat it as a direct-response channel. No click in the ear: demanding immediate conversions from a broadcast spot asks it for the wrong trade.
- It wastes if frequency isn't governed across platforms. The same listener saturated in streaming and never in podcast: contacts wasted on one side, reach missed on the other.
- It wastes if the creative isn't built for the ear. Recycling a TV spot's audio with no sonic idea of its own: the message passes and leaves no trace.
True for those building brand and reach: audio is a presence multiplier, not a click machine.
Bought for what it's worth, measured for real
We don't sell audio because it's fashionable, nor exclude it out of laziness. We put it in the plan only when it's the right medium for the goal, and we treat it with the same transparency rules as every other channel.
Media-neutral, first
We decide whether and how much audio is needed by comparing it with other media on the same goal. The share is set by its role in the plan, not by a rate card or a comfortable relationship.
Frequency governed across platforms
A contact cap that holds across broadcast, streaming and podcast, not siloed per buy. So we don't saturate the same people and miss the others.
Programmatic audio under your rules
When we buy automated, the same pre-bid levers as the rest of programmatic apply: inventory quality, context, price cap and frequency, written and legible.
Honest measurement of contribution
Brand lift and digital response where they exist, cross-media incrementality where it counts. We say what audio moved and what it didn't, without claiming credit for the last click.
Before you ask
Does radio still matter in 2026?
Yes, and listening figures stay broad: much of total listening time, especially in the car and in the morning, is still on broadcast. What changes is how you buy and measure it, not its ability to build reach.
Radio, streaming or podcast — which is best?
They aren't alternatives but different roles: radio brings habitual reach, streaming brings targeting and context, podcast brings trust and depth. The choice depends on the goal, and combining them with governed frequency often pays.
How do I know if audio worked?
On two planes: reach and frequency to see who you reached, brand lift and digital response (pixels, codes, visits) to see if you moved them. Where needed, we isolate the net contribution with cross-media measurement.
Is host-read worth the price premium?
When the show's audience is yours and the voice has credibility, yes: the trust it transfers is hard to replicate with a produced spot. When you're only after low-cost reach, no: dynamic audio or broadcast serve better.
Can I target and measure audio like digital?
On streaming and podcast, largely yes: data and context targeting, dynamic audio, pixels and attribution. On broadcast radio the logic stays reach and frequency, to be read alongside digital — not against it.
How much budget do I need to start?
It depends on the goal and the medium: programmatic audio and marketplaces let you start small and measurable; broadcast reach needs more weight so frequency isn't spread thin. We define the minimum useful threshold before spending.
Cases
From problem to result — anonymised.
Broad reach but no memory
Problem Many broadcast airings, frequency concentrated on the same listeners, and zero trace on recall.
Method Frequency governed across broadcast and streaming + a sonic idea of its own, measured in brand lift on exposed vs unexposed.
Result Pressure redistributed across more people and recall starting to move, not just airings delivered.
Host-read paid for blind
Problem Podcast sponsorships chosen on instinct, with no way to tie them to a response.
Method Dedicated codes and URLs per show + pixels on streaming, read alongside reach and not in its place.
Result Shows that drive response separated from those that only give presence, budget shifted to the former.
Audio bought because "it's done"
Problem A fixed audio budget every year, with no test against its role in the plan or against other media.
Method Media-neutral assessment of audio against the goal + dynamic audio to speak to different cities and dayparts.
Result The audio share re-justified by the role it plays, with relevant creative per market instead of a single spot.
