Digital Audio: The Evidence

Here we pull together research and case studies from IAB UK members that will help you to shape a successful digital audio strategy and see how brands are effectively tapping into this unique channel. All the evidence you need to unlock the power of digital audio advertising

Amplify your digital audio advertising

With over 60% of the UK adult population listening weekly, digital audio offers advertisers a potent mix of engaged listeners, high-quality content and immersive ad formats - making it a fixture on media plans, just as smart speakers have become fixtures in our homes. In fact, according to IAB UK’s annual Digital Adspend report with PwC, spend on digital audio has almost doubled between 2020 and 2022, with advertisers investing £186 million in it last year. As part of this, podcast investment has over tripled from £33 million in 2020 to £76 million in 2022. 

So, with more ad spend than ever going into digital audio, what do you need to know to ensure that your campaigns are delivering? And how can you make sure that your brand’s voice is not only adding to the listening experience, but resonating with a highly discerning audience? Look no further. From understanding attention in podcasting to leveraging actionable audio ads, we’ve curated evidence from across our audio membership into an essential toolkit to help you boost the effectiveness of your digital audio activity.
