USE CASE #1

Boosting conversions by 20% using Social Proof and A/B testing

The challenge

Hunkemöller wanted to increase website conversions and decrease bounce rates. However, the ecommerce team didn’t want to risk spending a lot of time launching expensive, timely campaigns that were ineffective. They needed a solution that could drive conversions while at the same time testing out what customers engaged with most to achieve stronger conversion rates.

The solution

The Insider team recommended adding Social Proof to the Hunkemöller site on desktop and mobile. On specific product pages, the Social Proof displayed how many customers had bought that product, giving visitors a sense of urgency to purchase based on their peers’ behavior. Insider’s customizable templates enabled the company to customize the Social Proof widget with its own branding in just minutes, without the need for dev or IT teams. 

To optimize the campaign and ensure it was cost-effective, Hunkemöller used Insider’s A/B testing solution, with 50% of site visitors being shown Social Proof scenarios and 50% not. There was a clear winner—within the first month of A/B testing Social Proof, Hunkemöller saw a 20% increase in conversions on desktop and a 13% increase in conversion on mobile. 

Not only did Hunkemöller hit its own business goals, but the campaign built loyalty with customers who discovered they could rely on Hunkemöller to serve them with the best, feel-good products.

“A 20% increase in conversions on desktop web using only Social Proof is truly remarkable. We also loved that Insider’s Social Proof campaigns are customizable—which enabled us to personalize it to our brand requirements.”

USE CASE #2

Boosting customer engagement with an 18% increase in Web Push opt-in

The challenge

Hunkemöller wanted to test out Web Push notifications as a new marketing channel. The brand was seeing successful campaigns across other channels, such as Email or SMS, but knew that there were still limitations due to delivery delays and lower engagement rates. Hunkemöller wanted to add another real-time notification touchpoint for customers who weren’t on their website—the team decided on Web Push.

The solution

Insider recommended deploying Web Push campaigns across ten of Hunkemöller’s key markets to see how the new channel performed The primary objective was to increase user engagement and boost opt-in rates. Across these ten markets, Hunkemöller achieved opt-in rates of 17%-18%, demonstrating that its audience was engaging with a new communication channel.

“When you see new things enter the market, you want to push yourself intellectually. Web Push is a new channel for us and yet the opt-ins are really huge, which tells us this is definitely a channel that our consumers are ready for.”
