Søstrene Grene boosts sales with merchandising

See how Søstrene Grene used Relewise merchandising to boost a specific a range of chairs and measured a 20.4% lift in add-to-cart events.

Søstrene Grene drove 20.4% more add-to-cart events with targeted merchandising

Søstrene Grene wanted to move a specific set of chair products faster, and didn't wanted to wait for shoppers to find them.

They used Relewise Merchandising to give the chairs stronger visibility in a controlled split test and measure what happened when the products were actively boosted.

More specifically, the merchandising rule was tested by splitting users into two groups: one exposed to the boosted chair products and one that was not. Relewise used the group value to apply the boost only to the selected test group, while Søstrene Grene’s experiment setup measured the difference in behavior. That made it possible to compare add-to-cart events and purchases between exposed and non-exposed users.

The result was clear

The boosted variant drove 20.4% more add-to-cart events for the selected chair products, with a 100% chance to win in the test. Purchases for the same products were also 7% higher in the boosted variant.

Merchandising often sits right between commercial urgency and customer experience.

When a team needs to move specific products, support a campaign, or react to inventory pressure, they need more than a manual change and a good feeling. They need to know whether the change actually works.

With Relewise, Søstrene Grene could act quickly, boost the relevant products, and compare performance against a control group. That made the effect visible at product level, instead of disappearing into broad site performance.

“The variant drove 20% more add-to-cart events and 7% higher sales. It’s a strong case: we can react fast and actually measure the sales impact.”

Nicolai says this :)

For other ecommerce companies, the takeaway is practical

Product discovery can be shaped around business priorities without losing sight of performance. When merchandising is connected to testing and measurement, teams can see whether a promotion, inventory push, or product focus is creating the behavior they intended.

In this case, that meant more shoppers adding the selected chairs to cart and a measurable lift in sales for those products!
