Tubby Todd lifts revenue per visitor 5.34% with Nostra

Tubby Todd, a family skincare brand, wanted to find new growth levers to maximize business performance beyond just acquiring more traffic. Their challenge was to improve how efficiently their existing site traffic converted into revenue without relying solely on increased acquisition spend. They partnered with the vendor Nostra to use its site speed optimization service.

Nostra improved site speed by operating at the edge to reduce latency and serve assets closer to shoppers, creating a faster experience without major engineering work. To measure the impact, Tubby Todd ran a controlled split test. The results were significant: Nostra delivered a 5.34% lift in revenue per visitor, a 3.90% increase in conversion rate, and a 21.7x ROI over the test period, proving site speed as a scalable growth lever.
