What is word-of-mouth marketing?
Word-of-mouth marketing, often referred to as WOMM, is about creating and amplifying conversations between people about a brand, a product, or an experience. It occurs when customers share authentic experiences that influence others’ purchasing decisions. Recommendations feel credible because they come from people the recipient already trusts. In this way, WOMM serves as an informal yet powerful part of the customer journey.
Although this phenomenon has always existed, social media and online communities have made word-of-mouth marketing more scalable. A single recommendation can now reach thousands of users in just a few minutes. That’s why you often see digital strategies integrating WOMM with, for example, SEO and social media marketing. When you boost your organic visibility through valuable content, you increase the likelihood that people will share what you create.
How do you use word-of-mouth marketing?
You actively influence WOMM by creating experiences that people feel are worth talking about. This can range from unexpectedly good customer service to unique product features that people want to share. WOMM is most effective when you combine the human factor with data and insights. For example, you can analyze which messages generate the most shares and then tailor your content and social media strategy accordingly.
Word-of-mouth doesn’t work like a traditional campaign with an end date. It’s an ongoing process where you nurture conversations through relationships and communities. That’s why branding and design can also play a role. A recognizable visual identity makes it easier for users to associate their experiences with your brand when they recommend it to others.
That's why you should use word-of-mouth marketing
Consumers trust recommendations from other consumers more than they trust paid advertising. Word-of-mouth therefore creates a form of social proof that supports all other marketing efforts. When you encourage customers to share positive stories, you strengthen both credibility and customer loyalty. WOMM can also reduce your overall marketing costs because organic recommendations serve as a complement to paid channels.
A well-functioning WOMM setup also increases the lifetime value per customer. Customers who come through referrals often spend more and stay longer. This builds a community around the brand, where users act as ambassadors. When you work strategically with WOMM, you can create a self-reinforcing cycle that combines performance and relationship-building.
What types and varieties are available?
- Organic WOMM: When customers spontaneously share positive experiences without receiving any incentives. This typically happens because the experience exceeds their expectations.
- Referral programs: Systematic referral programs in which you reward both the referrer and the new customer. These rewards can include discount codes, points, or other benefits.
- Buzz or viral marketing: Campaigns designed to spread quickly, often through emotion, humor, or storytelling, engaging a large audience in a short period of time.
- UGC (user-generated content): Content such as reviews,unboxing videos, or customer stories, where users themselves take ownership of the communication.
How do you use word-of-mouth marketing in practice?
You can measure the impact of WOMM in several ways. Referral sign-ups and social media engagement provide insight into how much your brand is actually being shared. Tracking new customers who come through referrals shows whether your setup is working. WOMM can also be linked to data from other disciplines. If you work with Google Ads, for example, you can analyze how search terms change as brand awareness grows through word-of-mouth.
In practice, you often start by identifying key moments in the customer journey when a customer is most likely to share an experience. This could be during onboarding, at the time of delivery, or after a positive service experience. You can then encourage sharing with well-chosen content that makes it easy to recommend to others—such as short videos, visual templates, or guides available on your own channels.
Another approach is to use social media as a lever. If you engage with users where they naturally share their experiences, you’ll achieve more authentic reach. This requires an understanding of how the platforms’ algorithms prioritize content and how compelling stories hold people’s attention. Here, social media marketing and branding strategy can go hand in hand.
What should you keep in mind?
Although WOMM may seem spontaneous, it requires a deliberate effort. You need to ensure that the experiences customers share align with your brand’s values and overall strategy. Negative word-of-mouth can spread just as quickly as positive word-of-mouth if customers’ expectations aren’t met. That’s why it’s important to regularly monitor social media mentions and respond quickly to feedback.
You also need to be realistic about the pace at which results will come. Word-of-mouth builds over time, and its impact depends on consistency and credibility. An overly generous incentive can come across as insincere and hurt your results. Instead, make sure the brand experience speaks for itself and that the customer journey genuinely makes people want to share it.
In other words: Word-of-mouth marketing is most effective when you view it as the combined result of strategy, content, service, and relationships. It’s less about pushing a message and more about creating something people actually want to talk about.
