Aggressive rollout plans for social proof at Windsor after 4.19% CVR uplift

The Windsor customer is a targeted and driven fashion-conscious shopper, often seeking inspiration for stunning outfits that impress at all of life’s occasions. 

Product discovery is vital for such customers, but being on-trend is also important to them. Windsor wanted to better harness their customers’ high purchase intent by helping them discover products they love more easily. 

Taggstar’s conversion messaging offer uses the incredible power of social proof to highlight what others are buying, what’s trending and bestsellers, improving confidence in purchase decisions.

Windsor ran a 2-week, 50/50 AB proof-of-concept test from Taggstar on its website from December 2025 to January 2026. The full-funnel test ran across PLP, PDP and cart and included conversion messages such as ‘Hot Pick! Sold X times since your last visit’ and ‘Viral Fave! Sold X times in X hrs’.

Freya Seeger, Sr. Director of Ecommerce at Windsor, says: “The fantastic results that Taggstar’s social proof conversion messaging delivered in the proof-of-concept have meant that we have quickly moved to test the benefits of even more targeted use of social proof.

“The implementation process was smooth and straightforward. The Taggstar team was organised, responsive, and proactive throughout the onboarding and testing phases. Integration was relatively lightweight, and communication between teams made it easy to move quickly and troubleshoot any questions along the way.

Seeger says that working with Taggstar has been a positive experience. She says: “The team has been collaborative, knowledgeable, and invested in helping us achieve strong results. They were attentive throughout the evaluation period and have continued to provide support, recommendations, and reporting as we continue to optimise. We appreciate that the Taggstar team is committed to helping us achieve our conversion targets and tailors ideas for our brand as to how to get there.”
