Fifty trial leads to wider social proof rollout for Spain’s Tendam

The initial test ran in October 2025 across Spain and Portugal for 57 days. Social proof messaging was implemented across the PLP and PDP, using 13 distinct message types. These included ‘Popular’, ‘Trending’, ‘Highly Requested’ and ‘Great Choice’.

The huge success of introducing social proof messaging in the initial Fifty pilot led Tendam to sign a two-year contract to continue its use at Fifty, as well as to roll it out to three other brands in its portfolio. It will now introduce social proof messaging to its underwear brand Women’secret, which has more than 700 points of sale in around 74 countries; womenswear and menswear brand Cortefiel, which has around 249 points of sale in more than 40 countries; and urban brand Springfield, which is present in more than 60 countries with more than 740 points of sale.

Peter Buckley, Chief Revenue Officer at Taggstar, said: “It’s not unusual for larger groups to test social proof messaging on a small scale initially, but, like Tendam, once they witness such success, they look to introduce the conversion rate booster to other brands in their portfolio too. 

“Tendam marks our first Spanish-headquartered customer as we continue to broaden our presence in brands across Europe, and we are pleased to be helping them drive more sales.”
