Case Study: Immi achieves a 7.1% conversion rate lift with Nostra

IMMI boosts conversion rate 7.1% with Nostra

The customer, Immi, a low-carb, high-protein ramen brand, faced a unique e-commerce challenge. Their customers engage in long, high-consideration shopping journeys, browsing recipes and reviews before subscribing. This behavior meant that site latency could compound across multiple page views, potentially interrupting the trust-building process and harming conversion rates. Immi partnered with the vendor Nostra to rigorously test the impact of site speed improvements on their business.

Nostra implemented its edge acceleration service, which primarily improves Time to First Byte (TTFB). Immi ran a controlled test with a live traffic holdout to measure Nostra's effect. The solution resulted in a 17.4% faster TTFB, which also led to an 8.1% improvement in Largest Contentful Paint (LCP). Most importantly, the Nostra-accelerated traffic saw a 7.1% lift in conversion rate. For Immi’s subscription model, this lift compounds into significant long-term value as each new subscriber contributes recurring revenue.
