A train operator partnered with audioadpro to deliver a five-week digital audio advertising campaign targeting students across Yorkshire & the East Midlands. Ads were delivered exclusively within this precision audience, with impressions also served to high-indexing postcodes targeting 18–24-year-olds associated with transactional data from Depop, Popworld and UCAS. The campaign ran across 300+ delivery lines throughout the full digital audio ecosystem – including music and radio streaming, podcasts and mobile in-game environments. Consolidated measurement provided the train operator with clear visibility into booking behaviour.
