What has been their challenge?
Colruyt wants visitors to enjoy a seamless, personalized experience from every touch point on their website. This includes their product detail pages where they want to increase customer engagement by showing the most relevant products. However, even with a large and diverse catalog, the number of alternatives might be incredibly small for a specific item.
How did we approach this case?
We used collaborative filtering in the algorithms in our modules to look at the behavior of the entire customer base to determine similar products based on the products that are commonly viewed or purchased together.
