Social proof is not only a proven solution to boost conversions on product listing and product detail pages, it is also a powerful tool to guide, reassure, and inspire shoppers at every stage of the customer journey including social media, digital ads, email marketing and on the eCommerce site.
How Bloomingdale’s Boosts Conversions with Social Proof in Email
Bloomingdale’s offers a great example of a successful cross-channel social proof approach. After experiencing strong results with social proof on its website and mobile app, Bloomingdale’s extended social proof to email in partnership with Taggstar and Movable Ink. Bloomingdale’s tested dynamic social proof in category-specific email campaigns, including beauty, ready-to-wear and menswear. The results exceeded all expectations with:
- 121% uplift in revenue per visitor (RPV)
- 87% increase in average order value (AOV)
- 3% uplift in click-through rate (CTR)
- 8% rise in conversion rate
Always looking for innovative ways to enhance the customer experience, Bloomingdale’s is already experimenting with new implementations and has a comprehensive roadmap that includes the rollout of social proof messaging to additional marketing channels.
How Retailers Can Use Social Proof Across the Customer Journey
By leveraging social proof across customer touchpoints, retailers and brands can deliver consistent experiences that build trust and drive immediate conversions, increase revenue per visitor and reduce bounce rates and cart abandonment.
- Research & Discovery: While shoppers are still researching and exploring products, retailers and brands can incorporate social proof into digital ads and social media to stand out, establish credibility, and drive traffic to their eCommerce site.
On the eCommerce site, impactful attribute messages on the PLP and PDP, highlighting relevant product features like “Best suited for oily skin” or social proof highlighting product popularity, such as “Trending – 21 sold in the last hour”, create more engaging experiences and help shoppers more easily find what they are looking for. By combining social proof and attribute messaging into one message such as “Vegan Leather – 16 sold in the last 24 hours”, you can further boost effectiveness and drive even higher conversion rates. - Consideration & Purchase: As shoppers narrow choices, urgency and validation become key to making informed purchase decisions. On product details pages and in the cart, real-time messaging, such as “200 bought in the last 24 hours,” helps build confidence, while dynamic badges that highlight special deals and promotions give a further nudge to buy.
Email marketing becomes even more effective when layered with social proof. Abandoned cart emails with messages such as “This item is a top-rated bestseller” or email nudges that highlight trending products can encourage shoppers to return and complete a purchase. - Post-Purchase & Retention: Post-purchase emails with social proof, highlighting that other people have purchased the same product, reinforce the customer’s purchase decision. Showcasing trending and relevant products along with social proof messaging can also encourage repeat spending and deeper engagement.
