The Challenge

Following the success of Tendam’s initial test of social proof messaging for its Fifty outlet brand, which operates in around 70 points of sale in six countries and online, the group then introduced social proof messaging for the biggest brand in its portfolio, Women’secret.

In its latest test, launched for Cortefiel on 30th June 2026, the company wanted to see whether social proof messaging could help Cortefiel customers discover products more easily and improve sales conversion.

The Solution

As with the Women’secret test, Tandem tested 13 message types on Cortefiel’s Spanish website across the PLP and PDP. These included ‘Popular’, ‘Trending’, ‘Highly Requested’ and ‘Great Choice’.

From an initial ROI of 10.4X for Fifty, it rose to more than 30X with the addition of Women’secret and, with Cortefiel, has now increased to an even more impressive 40X.

The Results

Like the Women’secret proof of concept, which generated a 4.63% conversion rate, Cortefiel also saw strong conversion results from social proof messaging, particularly on mobile, with conversion increasing by 5.63%. Across desktop and mobile, social proof messaging delivered a 3.09% uplift.

With each brand that Tendam has introduced social proof messaging for, the return on investment improves substantially. From an initial ROI of 10.4X for Fifty, it rose to more than 30X with the addition of Women’secret and, with Cortefiel, has now increased to an even more impressive 40X.

The Future

Taggstar will continue to further optimize the social proof messaging experience for Cortefiel customers this autumn, before designing a specific winter campaign for the brand.

Testimonials

Peter Buckley, Chief Revenue Officer at Taggstar, said: “We have many multi-brand customers and they naturally want to test the power of social proof individually for each to ensure it is a good fit for all their different brand and customer profiles.

The successes that Tendam has already witnessed with Fifty, Women’secret and now with Cortefiel show just how powerful it is, especially with the conversion uplifts witnessed on mobile, where the space to wow customers and convince them to buy is more limited.”
