A data-led static-creative refresh grew Podz in-app registrations 107% month over month, with the top ad cutting cost per registration to $2.55.
The Challenge
Podz’s existing ad set showed plateauing registration rates, despite stable click-through performance. Prior creatives were optimized for awareness and link clicks, not post-install actions. The challenge was to turn engagement into in-app registrations, the metric most closely tied to business growth.
Our Solution
Podz executed a strategic refresh of its install campaigns, rolling out new static creatives. The focus was to test new aspect ratios, visual hierarchies, and clearer calls to action designed to drive in-app registrations rather than generic installs.
1. Creative optimization. We introduced new static ad variants (like Install-Static-4x5-v5 and Install-Static-1x1-v5) focused on cleaner visuals, stronger CTAs, and simplified messaging, with direct value messaging, shorter copy, and clean framing. Each format tested optimized aspect ratios (1x1 and 4x5) for the mobile feed. These new creatives became the main growth driver, fueling a 107% total increase in in-app registrations versus the prior period.
2. Conversion-focused optimization. We shifted campaign objectives toward the in-app registration event instead of general installs and applied a 7-day click attribution window for more reliable tracking on actual sign-ups. This turned high CTRs into meaningful conversions, cutting average cost per registration to as low as $2.55.
3. Color and format testing. A/B testing between black and white background creatives revealed that white creatives outperformed: one ad saw a 1,716% improvement in results and +369% link clicks, showing users responded better to high-contrast, clean visuals.
4. Cost-efficiency adjustments. We adjusted bid caps and shifted budgets toward top-performing creatives early in the cycle, reducing wasted spend. Cost per result dropped from $8.28 to $3.70 for “Install-Static-4x5-v5” while maintaining volume.
5. A/B testing and iteration. We ran ongoing comparisons against prior-month baselines and rapidly scaled top performers within two weeks of launch.
