Should I Just Advertise in Podcasts?

Why Smart Brands Are Looking Beyond Podcasts to the Full Audio Landscape

Podcasting has firmly established itself as one of the UK’s fastest-growing media channels. With millions of listeners tuning in every week, it has become a powerful platform for storytelling, education, and entertainment. For advertisers, podcasts offer something highly attractive: engaged audiences, niche targeting, and long-form attention.

But there’s a crucial point many brands overlook.

While podcasts are growing rapidly, they represent just one part of a much larger—and more powerful—audio ecosystem. And for advertisers looking to scale, the real opportunity lies in combining podcasts with the broader world of audio advertising, particularly commercial radio and digital audio platforms.

The Scale of Podcast Growth in the UK

Podcast listening in the UK has reached mainstream adoption:

• Around 38 million people have listened to a podcast

• 20–23 million listen monthly

• 16–17 million listen weekly

  
  

This is a remarkable shift from a decade ago when podcasting was still niche.

Podcasts have carved out a strong position, particularly among:

• Younger audiences (25–44)

• Professionals and higher-income groups

• Digitally engaged consumers

  
  

They also offer deep engagement. Many listeners spend hours each week with their favourite shows, often forming strong connections with hosts. This makes podcast advertising—especially host-read ads—highly effective for trust and recall.

However, scale is where the limitation begins.

The Reality: Podcasts Are Big — But Not the Biggest

Despite their growth, podcasts still reach a smaller audience than radio.

In the UK:

• Podcasts reach ~16–17 million people weekly

• Radio reaches ~50 million people weekly

  
  

That’s nearly three times the audience.

This gap is critical for advertisers. Podcasts are powerful for depth—but radio and digital audio deliver unmatched breadth.

If podcasts are about engagement, then radio is about reach.

The most effective strategies don’t choose between the two—they combine them.

The Rise of Commercial Radio and Digital Audio

One of the most important shifts in UK media has been the rise of commercial radio.

Commercial radio now accounts for over half of all listening, overtaking the BBC. Networks like Heart, Capital, LBC, and Greatest Hits Radio attract tens of millions of listeners every week.

At the same time, audio consumption has become increasingly digital:

• Streaming radio via apps and websites

• Listening through smart speakers

• Audio embedded into connected devices (cars, consoles, TVs)

  
  

This has transformed radio into something much broader: digital audio at scale.

For advertisers, this means:

• The reach of traditional radio

• The targeting capabilities of digital platforms

Why Audio Advertising Works So Well Today

Audio has several unique advantages that make it particularly effective in today’s fragmented media landscape.

1. It Fits Into Everyday Life

Unlike visual media, audio doesn’t require full attention. People can listen while:

• Driving

• Working

• Exercising

• Cooking

  
  

This makes audio one of the few channels that can reach audiences during otherwise “unreachable” moments.

2. It Creates Personal Connection

Audio is intimate. Whether it’s a podcast host or a radio presenter, the human voice builds trust and familiarity.

This is why:

• Podcast ads feel like recommendations

• Radio ads benefit from repeated exposure and brand reinforcement

  
  

3. It Combines Scale and Targeting

Historically, advertisers had to choose:

• Radio = mass reach

• Digital = precise targeting

  
  

Now, modern audio platforms offer both.

Campaigns can be targeted based on:

• Location

• Age and gender

• Interests and behaviours

• Time of day

• Context (e.g. fitness, gaming, commuting)

  
  

This level of precision is transforming audio into a performance-driven channel—not just a branding tool.

Podcasts vs Radio: Not Competitors, But Complements

It’s tempting to view podcasts and radio as competing formats, but they serve different roles:

Podcasts

• Deep engagement

• Niche audiences

• Long-form content

• Strong trust via hosts

  
  

Radio & Digital Audio

• Mass reach

• High frequency

• Passive consumption

• Real-time relevance

  
  

Together, they form a powerful combination.

A listener might:

• Hear a brand repeatedly on radio during their commute

• Then engage more deeply with that brand through a podcast ad

  
  

This layered approach significantly increases effectiveness.

The Opportunity for Advertisers

The real opportunity lies in thinking beyond individual channels and embracing audio as a unified strategy.

Brands that rely solely on podcasts may struggle to scale.

Brands that rely solely on radio may miss precision targeting.

But brands that combine:

• Podcast advertising (depth)

• Radio & digital audio (scale + frequency)

  
  

…can achieve both awareness and conversion.

The New Era: Fully Managed Audio Advertising

One of the barriers to audio advertising historically has been complexity.

Creating and running campaigns required:

• Scriptwriting

• Voiceover recording

• Production

• Media buying across multiple platforms

  
  

Today, this is changing.

New platforms are making audio advertising:

• Faster to produce

• More affordable

• Easier to scale across channels

  
  

Fully managed solutions now allow businesses to:

• Create professional audio ads in minutes

• Distribute them across radio, podcasts, and digital platforms

• Target specific audiences with precision

  
  

This is opening up audio advertising to a much wider range of businesses—not just large brands.

Why Now Is the Moment for Audio

Several trends are converging to make audio more powerful than ever:

• Podcast adoption has reached mainstream levels

• Radio remains one of the UK’s largest media channels

• Digital listening continues to grow

• Smart speakers and connected devices are expanding access

• Audiences are increasingly comfortable with audio-first content

  
  

At the same time, other channels are becoming more challenging:

• Social media is saturated

• Display advertising suffers from low attention

• Privacy changes are limiting targeting

  
  

Audio, by contrast, offers a rare combination of:

• Attention

• Trust

• Scale

• Targeting

Conclusion

Podcasting has transformed the audio landscape, bringing millions of new listeners into the medium and creating highly engaged audiences.

But the bigger story is not just the rise of podcasts—it’s the rise of audio as a whole.

With tens of millions of weekly listeners across radio and digital platforms, audio remains one of the most powerful ways to reach people at scale. And when combined with the depth and engagement of podcasts, it becomes even more effective.

For advertisers, the message is clear:

• Don’t think in silos

• Don’t choose between podcasts and radio

• Think audio-first

  
  

Because in today’s media landscape, audio isn’t just growing—it’s becoming essential.
