Case Study: POPFLEX achieves 7.49% conversion lift with Nostra

POPFLEX lifts conversion rate 7.49% with Nostra

Popflex, a women's apparel brand, wanted to ensure its investment in Nostra's site acceleration service remained valuable before renewing its contract. The challenge was to reconfirm that Nostra's solution was still effectively removing site speed as a barrier to conversion for their visitors.

Nostra implemented a live A/B test on real production traffic. The results showed Nostra cut Time to First Byte by 25.8% and drove a 7.49% lift in conversion rate, a result validated by a highly significant Z-score of +5.73. This measurable impact made the decision to renew with Nostra a straightforward one for Popflex.
