Clicks Were Fine, Registrations Were Flat
Podz’s existing ad set showed plateauing registration rates, despite stable click-through performance. The earlier creatives had been built to win awareness and link clicks. Nobody had pointed them at what happens after the install. The challenge was to turn engagement into in-app registrations, the metric most closely tied to business growth.
This is a trap worth checking for in your own account. An ad set with a healthy click-through rate looks like it is working, right up until you compare it against the action you actually get paid for.
New Creative, and a White Background That Won
Podz refreshed its install campaigns with new static creatives. The plan was to test new aspect ratios, visual hierarchies, and clearer calls to action, all aimed squarely at in-app registrations.
1. Creative optimization. We introduced new static ad variants (like Install-Static-4x5-v5 and Install-Static-1x1-v5) focused on cleaner visuals, stronger calls to action (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 pointed the campaign objective at the in-app registration event and applied a 7-day click attribution window for more reliable tracking on actual sign-ups. That one change is what turned a high click-through rate (CTR) into 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. Worth trying on your own account before anything more elaborate. It costs an afternoon.
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 $3.68 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.
One Month Later, 1,243 More Registrations

In-app registrations climbed and click-through rates improved across every static variant, which is what a better creative looks like in the numbers. Top-performing ads landed cost per registration between $2.55 and $4.44, well below category benchmarks.
“Strataigize Marketing transformed our ad performance in just weeks. We saw massive growth, lower costs, and creative clarity that finally connected with our audience.”

Point the Creative at the Action You Want
Creative variation drives scale. Small visual and format changes, backed by data, can return far more than they cost. Matching the creative message to the final conversion goal (registrations) beat the engagement-focused campaigns outright, and fast testing cycles let the winning ad sets take over the budget quickly. Structured testing, targeted delivery, and moving money the moment the data said so turned modest campaigns into the growth driver.
If you take one thing into your own account, take this one. Name the action you actually want, set the campaign objective to that action, and design the picture to ask for it. Precision beat volume here, and it cost nothing but attention.
