Case Study: Euroflorist achieves 4.3% conversion uplift with Ascend by Evolv AI

Euroflorist sees conversions bloom with evolv

Euroflorist, one of Europe’s largest online florists, wanted to lift conversions on its product detail pages and accelerate testing beyond traditional A/B methods. Working with agency Online Dialogue, they ran a proof-of-concept using Ascend by Evolv AI to explore whether AI-driven, massively multivariate testing could find better combinations of page elements faster than manual A/B testing.

Using Ascend’s evolutionary algorithms to test eight page elements across generations, the 11-week experiment (four generations and 256 possible candidates) produced steadily improving results and a top-performing combination that increased conversions by 4.3%. Evolv AI’s Ascend also produced a winning variant that was independently confirmed via A/B testing, demonstrating measurable uplift and validating the platform’s ability to accelerate and scale CRO.
