The Objective

State-run vaccination campaigns have played a critical role in combating COVID-19 across the country. With this in mind, the government of a state with lower-than-average vaccination rates partnered with Katz Digital to run a podcast advertising campaign to evangelize the COVID-19 vaccine. The state government hoped to leverage the burgeoning podcast channel as a trustworthy and engaging vehicle to educate its citizens on the safe and necessary practice of getting vaccinated. While the campaign was live, Katz Digital utilized Veritonic’s brand lift capabilities to measure listener’s favorable perception and intent to receive a COVID-19 vaccine after hearing the ad.

The Approach

A state government leveraged Katz Digital’s dynamic ad insertion with geotargeting technology to reach its desired audience. To measure the impact of the campaign, Katz Digital utilized Veritonic’s Brand Lift capability. Brand lift data was collected by measuring an exposed versus unexposed group, with both segments containing similar demographic breakdowns from age and household income to political affiliation. Through Veritonic’s Brand Lift offering, Katz was able to identify the specific verbiage in the ads that impacted listeners the most. These creative insights were collected through Veritonic’s distinguished second-by-second engagement data.

Our Result

The COVID-19 vaccination campaign was highly effective in increasing favorability and intent for the vaccine. Among the unvaccinated, the campaign positively shifted favorable perceptions by 170% vs those unexposed, and the exposed were 25% more likely to receive a vaccine versus those unexposed. Second-by-second engagement data revealed specific dialogue that drove spikes in likability and ‘relevant to me’ among unvaccinated respondents.
