Why Are Advertisers Increasingly Embracing Programmatic Audio Ads? 🎧

By Max Legrand · GreyFox Ads · French AdTech perspective

Digital audio may be the little one in the Display family, but it is growing up fast. According to the Observatoire de l'e-pub figures cited in our original commentary, audio represented 6% of the Display category while recording +23% growth. Not bad for the youngest sibling. 🎧

1. How fast is programmatic audio advertising growing in France?

According to the latest Observatoire de l'e-pub figures discussed in our original post, audio advertising accounted for just 6% of Display yet grew by 23%. The percentages refer to the particular reporting period and classification used in that study (they should not be read as current market shares for every country or every type of digital audio).

Here in France, that contrast is striking: a relatively small category is growing much faster than its modest share might suggest. Why are advertisers paying attention?

Because getting in front of someone is no longer the hardest part of digital advertising. Just look at how many banners, videos and notifications compete for space on our screens every day. 😉 The real challenge is getting the message noticed and remembered.

2. Why can audio advertising be effective at capturing attention?

Audio has one wonderfully simple advantage: it can deliver a brand's message straight into the listener's ears, when that person has deliberately chosen to listen to music, a podcast or radio. 👂

It may also face less advertising clutter than the seemingly endless supply of display impressions, lengthy ad breaks on some connected-TV services or traditional broadcast breaks (the actual ad load varies significantly by platform and listening format).

That can make a message feel more distinctive. It does not mean every audio ad is automatically memorable: creative quality, placement, frequency and the listener's activity still matter.

For a wider discussion of advertising effectiveness, see why the Open Web has an attention problem and why viewability alone is not enough.

3. The right message at the right listening moment

Audio can accompany everyday moments when looking at a screen is impractical: cooking, commuting, exercising and working. These moments offer advertisers opportunities to reach people beyond conventional visual ad placements.

Then there is Dynamic Creative Optimisation (DCO). Our original example was an Audion campaign promoting the opening of McArthurGlen Paris-Giverny stores, with location-personalised messages along the lines of “just X km from you”.

Instead of serving exactly the same script to every listener, an audio campaign can adapt selected elements of the message using appropriate signals (subject to the platform's technical capabilities and applicable privacy rules).

Third-party audience data may also be available on some programmatic audio inventory, allowing additional targeting strategies where the data is suitable and lawfully usable.

4. Where can advertisers buy digital and programmatic audio inventory?

Digital audio is not one single ecosystem. The main listening environments mentioned in our original post include:

In other words, digital audio is broader than programmatic audio. Buying methods, formats and measurement differ between music streaming, podcast sponsorships, live radio streams and platform inventory.

5. Which advertisers are embracing programmatic audio?

According to the Alliance Digitale 2025 Barometer cited in our original commentary, retail and automotive advertisers were prominent users of audio advertising. Other categories appeared to be less active, which suggests room for further adoption (without proving that every underrepresented category will achieve the same results).

That is the exciting part. If audio can help brands reach consumers in moments that display and video struggle to address, the channel deserves to be considered in a broader media plan.

6. Does GreyFox Ads offer programmatic audio advertising?

We love the opportunity. But here comes a rare moment of commercial honesty. 😂 At GreyFox Ads, we said in our original post that we could only access around 10% of the audio supply relevant to our offering at the time. That is a description of our own limited coverage, not a statistic about the total French audio market.

So, no, we are not going to pretend to be the obvious partner for every audio campaign. We are watching this fast-developing channel with great interest. 🕵️

Where we can offer a stronger proposition today is quality Open Web display and video inventory. Our Master Curated Deal combines direct publisher supply paths, quality controls, attention-focused placement selection, audience strategies and transparent fees.

If your goal is to improve the quality and efficiency of programmatic display or video buying, we would be delighted to talk.
