Omni Calculator case study: from CMP switch to higher opt-in rates


consentmanager by iubenda case study: Omni Calculator

Omni Calculator is an online platform offering hundreds of specialized calculators across math, science, finance, health, and everyday life. Based in Poland and serving a global audience, the platform delivers 6 million page views a month and runs on an ad-funded model that depends on clean consent signals, broad addressable audiences, and fast page loads.

Their previous CMP covered the basics, but it didn’t give the team the design flexibility or reporting they needed to improve consent performance, and every rejected consent meant a smaller addressable audience for ad revenue. Readers also arrive from GDPR, CCPA/CPRA, LGPD, and other jurisdictions, and page speed had to stay intact: Core Web Vitals directly affect rankings on the calculator queries that drive their traffic.

By switching to consentmanager by iubenda, Omni Calculator lifted opt-in rates by 20% while keeping consent delivery under 200 milliseconds across 6 million monthly page views.

“Our opt-in rates had room to grow, and we knew a better CMP was the way to get there. consentmanager gave us the performance and reporting we needed to make it happen.”Alexander Utz, Ad Operations & Yield Manager, Omni Calculator

“Page speed is non-negotiable for us. Our entire growth depends on SEO, and the CMP had to load fast enough not to hurt Core Web Vitals while still giving us the controls and reporting we needed.”Alexander Utz, Ad Operations & Yield Manager, Omni Calculator
