Investment versus Insurance? Kabloom’s digital marketing campaign covers its own cost more than four times over

case study

Case summary: PReS 2021 digital campaign covered its own cost four times over

The European Paediatric Rheumatology Congress (PReS 2021) went virtual for a second year because of the COVID-19 pandemic. The Paediatric Rheumatology European Society needed abstract submissions and registrations from a specialist global audience in a crowded online event market.

What we did

Over eight months we ran a holistic campaign built on lessons from the 2020 edition and from related events. We targeted niche personas we had developed through long-term work with the PReS audience, ran search and social ads to build awareness, and rolled out an emailer campaign to grow website traffic and the database. Ad design and optimization ran throughout. See our multi-channel marketing approach.

The results

Digital marketing contributed 49% of all 2021 congress registrations. The target audience saw our ads up to 1.2 million times, the ads sent 12,984 leads to the congress website, and emailers averaged a 39% open rate. The campaign covered its own cost more than four times over.

Why it worked

Years of work with the same community meant we already knew which personas convert. Ads, search and email worked as one campaign over a long runway instead of a short burst before the deadline. That combination is why digital marketing worked as an investment for PReS rather than as insurance.
