Using Citroën’s sponsorship of Arsenal FC and the recently launched Citroën C4 Cactus, we developed a campaign that promoted the car manufacturer’s useful parking technologies. This digitally-led research-based campaign exceeded all of our targets: the cost per engagement (CPE) was 40% under target and we reached 16m people on social channels alone, leading to a cost per thousand (CPM) that was 151% under target.
