A recent study led by Mathias C. Streicher from the University of Innsbruck reveals that excessive secondary product displays in supermarket aisles can hinder sales. The research indicates that cluttered aisles discourage in-aisle browsing and negatively impact purchase behavior.
In field experiments, removing these displays resulted in an impressive 11.5% increase in sales, despite a reduction in the overall number of products available. This finding suggests that less can indeed be more when it comes to retail layout.
