About the client

Westwing is a home decor, design, and lifestyle platform that brings more beauty to its customers. Through three main channels—Clube, Now, and Lojas—the brand curates inspirational products from renowned names in the market, such as Le Creuset, Kitchenaid, and Luiza Perea, as well as its own brand, the Westwing Collection.

In 2011, the company entered the Brazilian market as a subsidiary of the German group Westwing. The company has been working with RTB House since 2020 to implement Deep Learning-based retargeting campaigns.

What they say about us

"The partnership with RTB House was instrumental in increasing the scale of retargeting campaigns on WestwingClube and WestwingNow. Our budget allocation was even more effective with them, which drove revenue growth and stable YOY ROI, even during Black Friday, the most challenging and competitive period for us in Brazil."

The challenge

Black Friday is the busiest period for retail in Brazil and a major focus for interior design brands. However, in 2022, it coincided with the opening weekend of the football World Cup, meaning any promotions would have to compete for the nation’s attention. RTB House had to bring greater scale and revenue to Westwing’s two websites while maintaining their ROI goals all in a fast-paced, highly competitive retail sector.


The solution

RTB House and Westwing worked closely to develop the best media strategy to deliver on campaigns goals. To anticipate Black Friday, account managers divided Westwing products into categories and promotional periods and created highly engaging dedicated banners for retargeting campaigns. This strategy helped drive incremental sales throughout the month.

Our Deep Learning-powered campaigns maximized conversions by delivering targeted, personalized ads, with relevant product recommendations, to customers who were ready to buy.


The result

Despite the World Cup opening and a 1% YOY drop in Black Friday month ecommerce sales in Brazil*, Westwing campaigns carried out with RTB House exceeded the company’s established goals. They brought in an 81% increase in revenue from October to November 2022, while keeping a stable ROI. Compared to the previous November, the campaigns achieved a 70% increase in revenue.

Deep Learning-powered ad campaigns are able to better serve relevant ad creatives to individuals and predict buyer intent. This better use of campaign resources led to much more compelling results for Westwing during Black Friday.
