Together with Google, we deployed an agile solution that empowered JYSK’s marketing team to enrich product feeds independently of the underlying product information management system. This gave the team a dedicated digital playground for rapid testing, learning and scaling without limitations, resulting in an estimated 20 million clicks across 29 markets.
Enriching product data with missing attributes and structured content increased product visibility across paid and organic listings, driving an estimated 20M additional clicks across 29 markets.
A dedicated sandbox environment enabled the marketing team to test, learn and deploy data enrichments without waiting on internal systems — at the exact pace the market demands.
Empowering specialists to operate independently of underlying IT systems eliminated technical delays and saved substantial operational hours previously lost to manual data enrichment.
JYSK, a home retailer with Scandinavian roots and global reach, operates in a highly competitive omnichannel retail market where Google search acts as a primary revenue driver. The search landscape is changing, and as algorithms increasingly reward rich formats, modern search requires structured, high-quality data. While JYSK has a strong foundation in search activities and already leverages AI tools like Smart Bidding, its ambitions continue to grow as new AI-driven opportunities emerge.
To scale search revenue, JYSK needed to rethink its product feeds to enable efficient data enrichment and drive AI-powered performance. It all came down to unlocking agility in how JYSK worked with its master data. To truly succeed, JYSK’s paid search specialists needed to adapt product feeds to match how consumers search and shop, acting on insights at market speed.
“The challenge for large organisations is often the same: product data is built for stability, not necessarily for the rapid testing cycles required by modern search,” explains Mathias Hillerup Larsen, CCO at s360. “We built Quantum to act as a bridge, allowing marketing teams to enrich and test data in real-time without affecting the integrity of the core internal systems or central data.”
Quantum is our proprietary feed enhancement tool that leverages AI to analyse, enrich, test and scale feed attributes across text, images and video.
Together with Google, we turned product data into a testable, scalable asset by deploying Quantum as an agile layer between JYSK’s master feed and its advertising channels. This setup enabled the marketing team to enrich data independently in a dedicated sandbox environment — testing and learning before scaling what worked.
Additionally, we used Google Gemini’s Nano Banana for image generation and Veo for visual optimisations. We combined Quantum with these advanced AI tools and validated every change in a continuous testing environment using Google’s open-source tool, FeedX.
The breakthrough came when our partner, s360, deployed Quantum as the solution that served as an agile layer between our master product feed and our advertising channels.
One early win involved product reviews. JYSK held valuable internal customer reviews, but the data was not structured for search algorithms. Using Quantum, we mapped this existing data into a format search engines recognise. This operational fix made hidden data visible, allowing shoppers to see star ratings and building trust directly into the ad.
To ensure every change drove true commercial value, we applied a proven testing framework.
“We split JYSK’s products into a control and a variant group. We test a change on the variant group, for example adding a review, to see if the new ad gets more clicks. We then switch the groups halfway through to remove any statistical noise,” adds Mathias Hillerup Larsen. “This ensures that when we call something a winner, often with 98% statistical significance, we are certain of its impact.”
This solution gave JYSK a dedicated space for rapid experimentation with zero internal risk, enabling the team to test hypotheses safely and instantly scale proven winners.

Based on results from 29 test markets, we estimated this change drove approximately 20 million additional clicks on JYSK’s Shopping ads. For a retailer operating at JYSK’s scale, that volume of incremental visibility represents a meaningful shift in market presence – traffic that would otherwise have gone to a competitor. Beyond the immediate visibility uplift, it eliminated countless hours previously spent on manual data enrichment.
Equally importantly, it fundamentally changed how JYSK’s marketing team collaborated with the wider business.
“Our process is now a continuous loop. We test an idea, and if it succeeds, we no longer approach the wider organisation with a hypothetical request; we come to the table with a proven winner. This shifts the conversation from a marketing belief to a business certainty,” emphasises Andreas Castillo Kristensen, Head of Digital Media at JYSK.
This left JYSK with an agile setup to test quickly, identify winners, and feed those successes back into its core strategy.
This case is internationally recognised, securing the Global Search Award for Best Global PPC Campaign, the Danish Digital Awards for Best Use of Data, and featuring as an official Google Client Case.
JYSK is a Danish retail chain founded in 1979 that sells home & living products in a Scandinavian style. It is one of Europe’s largest retail chains, operating 3,300+ stores across 50+ countries.
“s360’s structured approach to product data has made it much easier for us to work consistently across markets and categories and keep our setup scalable.”
“Every idea is tested, measured, and documented before anything is rolled out. Their approach ensures we act on evidence, not assumptions.”
“The e-commerce area is in constant development, and we want to stay ahead of the curve. s360 matches these ambitions and challenges us in the right places.”
