Case Study: Renowned Auto Company achieves higher engagement and lower CPE with Unified

Renowned Auto Brand Drives More Engagement and Efficiency With Instagram’s Square Format

Renowned Auto Company faced the challenge of standing out on Instagram’s highly visual, crowded platform and wanted to understand whether a small creative change—square versus landscape image format—could improve engagement and efficiency. Working with Unified and its platform, the company set up an A/B test to compare the two ad orientations using identical creative and targeting.

Unified implemented the test using Facebook’s 24-hour reach and frequency feature, keeping budgets low-risk while maximizing reach and limiting ad fatigue. The result was clear: the square format delivered 30.3% more engagement and a 26.1% lower cost per engagement than the landscape version, showing that subtle creative changes can have a measurable impact.
