Charles Darwin University

Charles Darwin University (CDU) is consistently ranked among the world's best universities despite being a young, dual-sector institution. But while their academic reputation was world-class, their digital marketing performance was not.

Their previous agency had promised student applications at a $50 CPA but delivered at $220 per application. That failure became the benchmark for Involve Digital's takeover. The goal was not traffic or engagement. It was student enrolments.

Every one of CDU's 17 faculties had its own goals, budget and creative requirements. The complexity was high. The expectations were higher.

Involve Digital took over all digital media buying and performance strategy for CDU. The first step was to rebuild from scratch: deep audience research and segmentation, custom campaign structures by faculty, funnel strategies aligned with student decision cycles, and cohesive but tailored messaging across each department.

We used Google Search, Google Display, Facebook, Instagram and remarketing, with strict adherence to on-brand creative, faculty-specific messaging and enrolment intent.

Creative testing was non-negotiable. We rolled out A/B-tested headlines, images and ad copy for each faculty, programmatic retargeting sequences, dynamic budget pacing to maximise returns within each channel, and consistent design language across banner, social and search ads. Every asset was tied back to faculty goals, prospective student intent, and the core promise of CDU's academic excellence.

Each CDU faculty operated its own budget with no cross-department flexibility. This meant our optimisation model had to work within tight budget silos. There was no room for error. Performance had to be exceptional everywhere, not just in aggregate.
