Amazon's integration with Global's radio brands signals something larger than the addition of new audio inventory to the Amazon DSP. It is the latest step in a sustained build-out that is changing what audio advertising can do for brands and, more importantly, how it should be planned.

In this month's #AskVector, we address the question that the Global announcement has prompted across more than a few planning conversations: what should brands do with Amazon's audio capabilities now, and how does this change the way audio fits into a retail media strategy?

Audio is no longer just awareness

For most of the history of audio advertising, the channel's job has been relatively well defined. Radio and podcast advertising builds brand recall, creates emotional connection, and reaches people at moments when visual media cannot. It has been evaluated on reach, frequency and brand metrics, and planned separately from the performance channels where conversion happens.

That positioning made sense when audio was a separate channel with separate measurement. It makes progressively less sense as Amazon's ecosystem creates direct connections between listening environments and commerce intelligence.

Amazon's first-party data covers what people search for, browse and buy. When that data is applied to audience targeting within audio environments, the distinction between brand advertising and performance advertising starts to dissolve. 

A listener who is served an audio ad on Heart because their shopping behaviour signals active consideration of a product category is not the same proposition as a listener reached at random by a demographic buy. The audience is qualified by intent, not just by age and gender.

Brands can now treat audio as a connected part of their commerce funnel rather than a separate awareness investment that sits above it.

What the Amazon audio ecosystem actually looks like

Amazon's audio footprint is more substantial than most brands' current planning reflects.

Within Amazon's owned and operated properties, the audio stack includes Amazon Music, Alexa, Wondery podcasts, Audible and Twitch. 

Alexa in particular represents a distinctive position: Amazon's smart speaker platform is already the primary listening device for Global's radio brands in the UK, with those stations accumulating over one billion listening hours on Alexa in 2025 alone.

Through the Amazon DSP, that owned inventory is now supplemented by programmatic access to Spotify's audio and video catalogue and Global's full portfolio of UK commercial radio stations and podcast titles. Together, these environments span music streaming, talk radio, news, sport, long-form podcasts and smart speaker listening across tens of millions of regular listeners in the UK.

The question is not whether Amazon has the audio inventory to build at scale. It clearly does. The question is whether brands are planning against that inventory with the strategic coherence the ecosystem warrants.

Tactical versus strategic audio

Most brands currently using audio within Amazon DSP treat it tactically. An audio placement is added to an existing campaign to extend reach into a listening context, evaluated on the same short-term metrics as display, and treated as essentially interchangeable with other formats.

Strategic audio use is different. It starts with the audience, not the format. Amazon's commerce data can identify listeners who are actively in-market for a category, in the early stages of consideration, or who represent high-value cohorts based on past purchase behaviour. 

Audio can then be deployed to reach those audiences at moments of attention that are genuinely complementary to the rest of the campaign, building brand preference and shaping intent before a shopper reaches the point of purchase.

The outcome this is building toward is what attention plus intent looks like in audio: reaching an audience that is both mentally available to receive a brand message and demonstrably close to a buying decision. That combination has not been possible in audio advertising before.

Ecosystem thinking, not channel silos

The real opportunity, as Amazon's audio build-out continues, is not in optimising individual audio placements. It is in building a connected audio system across music streaming, smart speakers, broadcast radio and podcasts, planned and measured as a coherent whole rather than a series of separate channel decisions.

Brands that evaluate Amazon Music and Global and Spotify as individual options and choose between them are missing an opportunity. The value is in understanding how listening behaviour varies across formats, how Amazon's audience data connects them, and how audio exposure at different stages of a listening session or a customer journey contributes to commercial outcomes that are measurable end-to-end.

The question we are increasingly putting to brand partners is whether their audio strategy is built to be heard or built to perform. Those are not the same thing, and for the first time in audio advertising, there is a genuine infrastructure for the latter.
