Products with 5 reviews generate 270% more sales than products without.
The Spiegel research team partnered with PowerReviews to analyze millions of customer experiences from two online retailers featuring primarily lower-priced product categories and a third online retailer of high-priced gifts. We looked at how customers’ exposure to and interaction with online reviews affected their purchase behavior for up to a year.
The statistic is significant because customer reviews play a critical role in shaping purchasing decisions. With five reviews, a product earns greater credibility and trust, leading to a substantial increase in sales. This highlights the influence of social proof and emphasizes the importance of encouraging customers to review products, ultimately driving business growth.
