Case Study: DeFacto boosts user logins with VWO

DeFacto Increases User Logins and Registrations During Black Friday Using VWO

DeFacto, a global fashion retailer based in Istanbul, wanted to improve user registrations and logins during the Black Friday season. The team had noticed that while traffic and sales rose during the sale period, user acquisition did not, making it harder to grow lifetime value from new shoppers. They chose VWO and its A/B testing capabilities to analyze behavior and test ideas more efficiently.

Using VWO’s Visual Editor, DeFacto ran an A/B test that kept the existing header icons but added a persistent, animated notification badge to draw attention to the login/registration area. The variation won after 10 days, and VWO helped DeFacto increase user logins by 21.53% and registrations by 8.55%, showing that a small UX change can meaningfully boost conversions.
