Objectives
· Lower cost per acquisition (CPA)
· Improve the profitability of programmatic campaigns
Methodology
A/B Testing & Experimentation
To increase campaign impact, NÜ implemented a structured testing strategy focusing on key variables: audiences, ad formats (video, banners, native ads), and creative messaging. This approach quickly revealed the most effective combinations optimizing both engagement and conversions. The results proved conclusive: continuously refined campaigns that were more accurate and better aligned with user expectations.
Incremental measurement
NÜ used an incremental approach to accurately measure the true impact of Popeye’s advertising. Rather than relying solely on engagement metrics, we tracked conversions directly attributable to ad exposure. This strategy validated campaign effectiveness by clearly isolating the results generated by programmatic activations.
Continuous optimization
Throughout the campaign, NÜ managed budgets in real time adjusting investments based on observed performance. Optimization efforts were based on precise indicators like CPA, total conversions, and repeat visits. This allowed us to concentrate spending on the most profitable segments and maximize media efficiency.
