Case Study: Aldi improves app conversion with Taggstar social proof messaging

Extension of social proof messaging from Taggstar to the Aldi App delivers conversion rate improvement

Aldi, Britain’s fifth-largest supermarket, wanted to extend the social proof messaging it already used successfully on its website into its app. The challenge was to help customers move quickly on its fast-selling Specialbuys range, where popular items often sell out fast online and in store. Taggstar’s social proof solution, including bestseller and review messaging, was chosen to support this goal.

Taggstar implemented eight message types across the Aldi app’s Specialbuys category, including Selling Quickly, Top Seller, Category Best Seller, and review-based messaging from Bazaarvoice. Over a four-and-a-half-month trial that began in May 2021, Aldi saw a good conversion rate uplift and a better buying experience for customers. The retailer now plans to expand Taggstar’s social proof messaging to additional app categories and continue optimizing across both app and website.
