Maximizing Retail Impact: The Role of Digital Signage in Price Discounts

Retailers are increasingly adopting digital signage as a dynamic tool to promote price discounts, complementing traditional printed displays. A recent study of Nanni & Ordanini (2024) sheds light on how this integration influences consumer spending, particularly on discounted products. While digital signage is often lauded for its modern appeal and ability to attract attention, its effectiveness varies based on the proximity of the advertised products to the screens.

The Experiment 

Conducted in two grocery stores, researchers analyzed the behavior of over 7,000 shoppers through two field experiments. Digital screens were strategically placed in high-traffic areas, and promotional content alternated with service messages. Products advertised ranged from fruits and vegetables to personal care items, both near and far from the screens.

The findings revealed a striking dynamic: digital signage effectively boosted sales of discounted items located far from the screens, but had negligible impact on nearby products. For items close to the screens, traditional printed tags appeared sufficient in conveying the discount message. In contrast, distant products benefited from the dual exposure of dynamic screens and shelf-level printed tags.

Why Does Distance Matter?

The study attributes the increased sales of distant products to the ability of digital signage to capture consumer attention earlier in their shopping journey. By the time customers reached the aisle with the discounted item, traditional printed tags reinforced the initial message, making the promotion more memorable. For nearby products, however, the overlap of digital and printed media seemed redundant, leading to diminished effectiveness.

Implications for Retailers

This research challenges the assumption that digital signage universally enhances sales. Instead, it highlights the importance of strategic content placement:

• Maximize Returns on Far Products: Retailers should leverage digital signage for promoting discounts on items located farther from the screen’s physical location.
• Reassess Close-Range Promotions: For products in proximity to screens, relying on traditional displays may be more cost-effective and equally impactful.
• Optimize Promotional Balance: Combining digital signage with printed displays thoughtfully can amplify the promotional message without redundancy.

Lost Value in Current Practices

A critical insight from the study addresses lost value due to inefficient use of digital signage. Retailers often invest heavily in these systems without accounting for the diminishing returns when promoting nearby products. Misaligned promotional strategies could inadvertently dilute the impact of discounts, limiting their potential to drive incremental revenue.

Changing Dynamics of Promotions

The study also underscores evolving dynamics in promotional strategies. As consumer attention spans shorten, the interplay between dynamic content and static media becomes pivotal. Retailers must navigate these shifts to ensure promotional messages resonate effectively.

Broader Takeaways

The findings serve as a call to action for retailers, digital signage providers, and researchers. Understanding the nuanced relationship between promotional media and product placement can guide better investment decisions and enhance the overall shopping experience. By aligning technology with strategic objectives, retailers can unlock the full potential of their marketing efforts.

This research provides a framework for optimizing digital signage, emphasizing the need for targeted, data-driven approaches to in-store promotions. It invites further exploration into how content design, product type, and store layout influence consumer behavior, paving the way for innovations in retail marketing.
