Engineering Word-of-Mouth for eCommerce Success

Sambuno Marketing Journal

In this episode, we explore how word-of-mouth continues to be one of the most powerful—and underrated—growth channels for eCommerce brands. Far more cost-effective than traditional advertising, word-of-mouth not only drives new customer acquisition but also fosters deep brand loyalty. But make no mistake: while it may appear organic, smart brands know how to engineer it. We break down practical strategies for sparking and scaling word-of-mouth, from delivering products worth talking about to encouraging user-generated content, setting up high-impact referral and loyalty programs, and crafting experiences that people want to share. We also cover which metrics matter—like referral traffic and repeat purchase rates—and how to build a self-sustaining growth engine powered by delighted, vocal customers.
