Norwegian sports and leisure retailer’s real-time social proof messaging trial delivered a 9.05% conversion rate uplift in only 22 days and marks Taggstar’s first Norwegian-based customer.

The speed to value for Norwegian retailer’s implementation of real-time social proof messaging proved that the technology worked for its customer base, helping to deliver a 9.05% conversion rate uplift in only 22 days despite a limited funnel implementation. The technology is now being tested further across the business.

Background, is one of Norway’s leading eCommerce companies, a four time finalist in E-Commerce of the Year – winners twice, most recently in 2020 when they beat 1,400 others to the title!  The company was originally founded from the kitchen counter of Silje Landevåg’s Oslo apartment in 2009. Its website was launched in 2010, backed by an autostore robot warehouse which now comprises 25 robots to enable ultra-fast shipping. Since then the company has grown to a company of 60 employees, with a customer base of women who want fashionable leisure and sports clothing and footwear.

With its on-trend product range the company also has a significant social media following which offers greater opportunity to engage and share customer experience. It describes its mission as making “sporty girls smile”. As well as womenswear has recently expanded to sell a range of menswear and gifts. Its growing sales means it is now one of Norway’s biggest online retailers.

Challenge already has a strong social media following but wanted to make further use of the power of its existing customers to drive conversion and online sales higher by sharing their behaviour to influence new browsers who may be considering a purchase. With the recent addition of a limited menswear range also wanted to help guide potential and existing customers through the shopping journey and expanded product ranges to ensure that they can buy with confidence.

Solution was introduced to Taggstar through specialist commerce agency Avensia, with whom Taggstar has worked on other social proof implementations. A range of 11 message types were used, including Quantity Purchased – Don’t Miss Out, Added to Bag – In Demand and Audience Views – Popular. These were used across the retailer’s Product Details Pages (PDP) and Basket pages in the first phase of deployment.

Result saw a 9.05% conversion rate uplift in only 22 days which amounted to 1,353 incremental orders. This success has encouraged to extend its use of social proof messaging further. Initially the focus will be on optimising the existing messaging, as well as driving mobile conversion. However, the retailer, which is also investing in driving additional traffic to its site, intends to extend social proof messaging to its Product List Pages (PLP) and Category pages.

Sindre Landevag, CEO of, said: “It was important for our first use of social proof messaging that we chose a leader in this space in, who we had confidence and could trust. Taggstar was that leader.”

Andreas Nordas, Ecommerce Manager of, said: “Our implementation of social proof messaging not only delivered great results, with a 9.05% increase in conversion rates, but it did so quickly – in less than a month. The messaging has resonated well with our customer base and the messaging design also fits well with our branding.”

Peter Buckley, CRO at Taggstar, said: “Although we have experience in the Nordics market represents our first Norwegian-headquartered client. We are pleased that we have been able to help drive impressive results for their business and illustrate the power of social proof messaging.”
