What LEROY MERLIN Portugal wanted

LEROY MERLIN Portugal is the Portuguese branch of the leading European home improvement and gardening retailer. Headquartered in France, they operate more than 290 stores across 12 countries.

As 2020 drove a global shift towards ecommerce, LEROY MERLIN Portugal’s performance marketing team and digital agency needed a solution to enable retargeting campaigns on Facebook and Google. GDPR compliance and personal data protection anchored their search, necessitating a first-party data solution that could still provide highly customizable audiences.

LEROY MERLIN Portugal came to Kevel to segment their traffic into defined first-party audiences in a privacy-first way. Kevel Audience gathered LEROY MERLIN Portugal's behavioral data, joined it with disparate data silos and ecommerce activity, and used that to enhance LEROY MERLIN Portugal's larger digital modernization efforts. Kevel enabled LEROY MERLIN Portugal's larger digital modernization efforts, including connecting data silos and bringing ecommerce activity together with behavioral data. 

Using these audiences, LEROY MERLIN Portugal crafted personalized messaging on their website based on Audience data of user product interactions to drive sales more efficiently.

LEROY MERLIN Portugal quickly adds user-personalized banners to their website

LEROY MERLIN Portugal’s personalization team used Kevel to develop audience segments with affinities for particular products. These audiences were activated to a third-party personalization platform managing homepage banners, and the team deployed custom homepage banners featuring images that reflected primary user interests.

For example, a customer  who had viewed, added to cart, or purchased power tools on LEROY MERLIN Portugal's site within a specific time frame would see a custom banner image with those products, while a different customer shopping for outdoor furniture would see a banner featuring a lawn set.

Group B drove higher average order value, conversion rate, and revenue per session when compared to Group A. 

  • Average Order Value (AOV) = +2.87%
  • Conversion Rate (CVR%) = +16.26%
  • Revenue Per Session (RPS) = +19.08%
