Radiocentre Ireland's April webinar explored how digital audio and broadcast radio can be linked more clearly to business outcomes through attribution, moving the conversation from exposure to action.
Ben Ramm from Bauer Media Group began by explaining digital audio attribution, focusing on audio tracking pixels. These pixels are triggered when an audio ad is heard and can then help track whether a listener goes on to visit a website or take another action. This allows advertisers to see campaign performance in real time, rather than waiting until after a campaign has finished. It also gives advertisers more transparency, enabling them to assess return on investment, understand customer journeys, identify drop-off points on websites, and compare different creative executions through A/B testing.
Ben then turned to broadcast radio attribution, which has traditionally been more difficult because live radio listening often happens offline, such as in the car or at home, without a direct digital click path. He explained that Bauer uses Veritone Attribute, an AI-based platform that connects radio ad logs with a client’s website analytics. The system looks at whether website traffic increases shortly after an ad has aired. Bauer typically uses an eight-minute attribution window, based on Veritone’s analysis of previous campaigns, although this can be adjusted depending on the campaign, category and expected response behaviour.
A key point was that broadcast attribution is not a perfect one-to-one tracking system. Unlike digital, it cannot prove that an individual listener heard an ad and then visited a website. Instead, it works at a broader campaign level by comparing website activity during periods when ads aired against normal baseline traffic. This allows advertisers to see uplift, identify the best-performing dayparts, assess the impact of frequency, and optimise future radio schedules.
The discussion also addressed the delayed effect of radio. Because people often listen while driving, cooking or doing other activities, they may not respond immediately. Ben acknowledged that attribution windows can be extended, sometimes up to 24 hours, but this requires careful caveating because the longer the window, the greater the risk of misattribution.
Privacy and data access were also discussed. Digital audio attribution is moving away from third-party tracking towards server-to-server models, while broadcast attribution requires client participation through access to analytics platforms. Ben suggested that broadcasters can reassure clients by involving technical experts, using non-disclosure agreements, and making clear that data access is limited to the campaign period and remains under the client’s control.
Overall, the webinar showed that attribution is helping audio move beyond its traditional reputation as a high-ROI medium by giving advertisers more evidence of how campaigns drive response. While attribution is not perfect, especially for broadcast radio, it provides a more practical, data-led way to understand, optimise and demonstrate the business impact of audio campaigns.
