Cernucci uplifts online conversion by 3.15% with Taggstar Social Proof Pro Plan

As a digital-first retailer with fast-moving product lines, Cernucci is constantly seeking ways to enhance the on-site experience, boost conversions and maximize revenue from every visitor. 

When the company first met with Taggstar in January 2025, it wanted to also add user-generated content to its site to create a more community-driven experience for its customers. 

It hoped this would drive additional conversions and orders; however, it was essential for Cernucci to maintain its premium feel, ensuring that the on-site experience remained true to the brand’s style and identity.

Cernucci ran a 70-day test of social proof messaging across its UK and US websites between the end of June and the beginning of September. The test demonstrated statistical significance after a month, but Cernucci were keen to extend the test to be confident that Social Proof would continue to deliver uplifts.

All seven real-time messaging types from Taggstar’s Social Proof Pro Plan were used across the full funnel. The Social Proof Pro Plan, one of Taggstar’s most recent innovations, allows smaller or emerging speciality brands and retailers access to the same social proof technology used by many of retail’s giants today. Messages included ‘IN DEMAND – Sold 27 times in the last 5 days’ and ‘TOP CHOICE – Added to bag 100+ times in the last 5 days’.

Cernucci and the Taggstar team are continuing to work together to develop the brand’s social proof messaging strategy, as well as testing a new UI for seasonal campaigns. 

Cernucci has already tested animated icons versus 2D messaging. Animated icons are an additional option for social proof messaging that help further capture customer interest and attention by adding movement to message icons. They have since rolled out across the site for Cernucci’s recent Black Friday and Cyber Monday campaigns. 

Victoria Pearson, Director of Ecommerce at Cernucci, says: “We have been thrilled at the strong results that Taggstar’s social proof messaging has delivered across all our trading metrics. The ROI for the test itself was strong, but at 3,272% ROI for the full 12-month contract is even more impressive.” 

“As well as delivering strong results, working with Taggstar has been stress-free, with the team determined to help us achieve the best results we can. We look forward to seeing how else social proof messaging can help us boost sales, conversion and better help our customers.”
