Case Study: Dannon achieves a 29% increase in loyalty program registrations with AB Tasty

Dannon increases loyalty program registrations by 29%

Dannon, the iconic yogurt and dairy brand, wanted to increase loyalty program sign-ups on its Spanish website after noticing visitors were confused by “register” and “login” CTAs shown together in a pop-up. Working with AB Tasty and its A/B testing tools, Dannon set out to simplify the experience and boost registrations.

AB Tasty helped Dannon implement a tabbed pop-up that clearly separated registration and login and ran a five-month A/B test with over 600,000 users. The new design delivered measurable impact: registrations up 29%, logins up 78%, revisit rate up 135%, and the test reached 100% reliability—demonstrating AB Tasty’s ability to drive conversion improvements through simple UX changes.
