Case Study: 67% Savings on App Installs for a European Food Delivery Platform
 

The Challenge: A food delivery app launching in Portugal needed rapid user acquisition. The business owner set a strict ceiling: Keep Cost Per Install (CPI) under €5.00 to maintain a viable profit margin.

The Strategy: Instead of burning through budget on broad targeting, I implemented a hyper-localized Google App Campaign. By feeding Google’s algorithm high-intent audience signals in the first 48 hours and pairing them with high-converting, time-sensitive creatives (targeting peak hunger hours), the campaign hit maximum efficiency almost instantly.

The Results:

Client Target CPI: < €5.00

Achieved CPI: €1.62 (67.6% under budget!) * 

Total Installs: 290 premium users in just 2 weeks

Click-to-Install Rate: 11.78% (Massive intent alignment)

Total Ad Spend: Only €468

By structuring the campaign correctly from day one, I didn't just meet the client's growth goals—I secured nearly 300 new customers at a fraction of what they expected to pay, leaving them with massive headroom to drive profitable, repeat food orders.
