DAX makes measuring the performance of your audio ads easy. Find out who listened to your ad and what they went on to do after they heard it.

Having performance data to hand lets you effectively plan, optimise and evaluate your ad campaigns. Our Listener Insight ID tool equips advertisers and agencies with an accessible, intuitive way to test, learn and improve on digital audio.

For each device DAX serves your ad to, Listener Insight ID generates a unique anonymous ID. When those IDs visit your brand website, the tool tracks when they visit, how often they visit, which sections of your website they go to and which execution drove them there.

All this information is available through an online dashboard.

With the Listener Insight ID dashboard, you can:

  • See and quantify how campaigns are performing on a daily basis
  • Track post-listen behaviour to online activity in real time
  • Monitor metrics like impressions and conversion rates
  • Derive audience insights, including behavioural and demographic traits


When your campaign goals are to drive brand awareness, perception and purchase intent, DAX post-campaign brand studies are a survey-based method of measuring the effects of your campaign on brand metrics among real listeners.


When you launch a location sync campaign on DAX, your audio ad will be delivered to anyone within a 1km radius of the shop, attraction, venue or out-of-home ad that you designate.

Through partnerships with location data specialists and by tracking the device IDs entering that 1km radius, DAX will measure the additional footfall generated by your location sync campaign.

What’s more, you can identify where the listener was when they heard the ad, how far they travelled to the location, how long after hearing the ad they visited and what demographic and behavioural traits the listener demonstrates in their other online activity.
