Word of Mouth Marketing (WOMM) is one of the most influential tools a small business can use. Unlike traditional advertising, which depends on paid placements and polished messaging, WOMM is driven by genuine conversations and real-life recommendations. When customers share positive experiences, whether in person or online, they help build trust and credibility for a brand, often influencing others to engage or make a purchase.
Historically, word of mouth was spread through face-to-face chats, phone calls, and personal referrals. Small businesses built their reputations locally, thriving on strong relationships and consistent service. While those traditional roots remain relevant, today’s word of mouth has evolved to include social media, online reviews, and influencer endorsements, allowing even the smallest businesses to reach wider audiences.
In fact, data strongly supports its impact. According to Nielsen, 92% of consumers trust recommendations from people they know over any other form of advertising, while reviews and endorsements from trusted figures, such as celebrities or influencers, also carry significant weight. This unparalleled level of trust makes WOMM not just effective, but essential for any small business looking to grow authentically and affordably.
So, what is word of mouth marketing, how easy is it to roll out for your small business and is it worth it? We’ve put together a short guide to help you decide.
What is word of mouth marketing?
Word of Mouth Marketing (WOMM) is when customers voluntarily share their experiences about a business with others. It can occur naturally, without any prompting, or be encouraged through strategic efforts by the business.
Types of WOMM
- Organic WOMM – This occurs when customers genuinely enjoy a product or service and talk about it with friends, family, or social media followers. There is no incentive involved; it stems purely from enthusiasm and satisfaction.
- Amplified WOMM – In this case, businesses actively encourage and promote word-of-mouth sharing. This could be through referral schemes, social media engagement, or influencer collaborations.
Why is WOMM essential for small businesses?
Small businesses often operate with limited marketing budgets, making WOMM an invaluable strategy. It allows companies to grow organically, as happy customers naturally spread the word about great products and services. Additionally, recommendations from friends and family carry significant weight, making potential customers more likely to trust and act on them.
Why do people share recommendations?
People are naturally inclined to share recommendations, and much of this behaviour is rooted in psychology. At the heart of it lies the principle of social proof – when people endorse a product or service, it reinforces their own decision-making and provides a sense of validation. Sharing a great experience also creates an emotional payoff; there’s satisfaction in helping others discover something valuable.
On a deeper level, recommending a business can subtly provide a positive reputation, as it signals taste, insight, or being ‘in the know.’ This intrinsic motivation is often complemented by external incentives, such as discounts or referral rewards, which can further nudge people to spread the word.
WOMM channels in the digital era
Today, digital platforms have transformed how word of mouth spreads. With just a few clicks, customers can share their experiences with a much larger audience. Some of the most powerful modern WOMM channels include:
- Social media: Platforms like Facebook, Instagram, Twitter, TikTok, and LinkedIn allow businesses to engage with customers and encourage them to share their experiences.
- Online reviews & ratings: Feefo, Trustpilot and Checkatrade can be essential tools for businesses that rely on reputation and customer feedback.
- Influencer marketing: Businesses collaborate with micro-influencers for authentic promotion, leveraging their credibility and following.
- Referral & loyalty Programmes: Offering incentives for referrals helps encourage organic recommendations.
- User-Generated Content (UGC): Customers posting photos, testimonials, and reviews about a business can generate powerful word-of-mouth exposure.
As an example: A small café that once relied on local chatter can now experience a surge in customers due to a viral Instagram post or a glowing online review.
How to use Word of Mouth Marketing for your small business
Deliver outstanding service & experiences
Providing exceptional service is the foundation of WOMM. Customers only recommend businesses they genuinely love. A memorable, seamless experience makes people more likely to talk positively about your brand, both online and offline.
Encourage reviews & testimonials
Asking satisfied customers to leave reviews can significantly boost credibility. Positive reviews serve as social proof, reassuring potential customers and influencing their purchasing decisions.
Leverage social media
Encourage customers to tag your business, use hashtags, and share their experiences online. This not only increases your visibility but also creates a stream of authentic content that can attract new audiences.
Use referral & loyalty programmes
Reward customers for referring friends to your business. These programmes turn happy customers into active promoters, helping you grow your base through trusted personal networks.
Work with micro-influencers & brand advocates
Authentic endorsements from real people can be highly effective. Micro-influencers, in particular, often have stronger connections with their followers, making their recommendations more persuasive.
Engage in community & networking
Attending local events and networking can help spread the word about your business. Building genuine relationships in your community can lead to lasting loyalty and consistent word-of-mouth referrals.
Benefits of Word of Mouth Marketing
Higher trust & credibility
Recommendations from friends and family are more influential than traditional advertising. People tend to trust real experiences over brand messages, making word of mouth a powerful driver of consumer confidence.
Cost-effective
WOMM requires little to no financial investment compared to paid advertising. This makes it especially valuable for small businesses looking to maximise impact without straining their budget.
Builds customer loyalty
Encouraging repeat customers helps businesses thrive. When people feel heard and valued, they’re more likely to return and promote your business to others.
Boosts brand awareness
More exposure with less effort. Every share, mention, or recommendation extends your reach to new potential customers without the need for constant promotion.
Increases conversions
Referred customers are more likely to make a purchase. They often arrive with a level of trust already established, making them easier to convert and more likely to become loyal patrons.
Costs of using Word of Mouth Marketing
Organic WOMM: Free, however it relies on satisfied customers receiving positive experiences and natural advocacy. Conversely if customers have negative experiences the cost to recover from this could be detrimental.
Paid WOMM Strategies:
- Offering referral rewards such as discounts, free products.
- Collaborating with influencers.
- Investing in reputation management tools.
WOMM is far more cost-effective than traditional advertising and has long-term benefits.
Small businesses that benefit most from WOMM
Local service-based businesses
Businesses that rely on trust and credibility naturally benefit from WOMM. Restaurants, cafés, salons, auto mechanics, and cleaning services all thrive on personal recommendations. If someone has a great dining experience, a fabulous haircut, or finds a trustworthy mechanic, they are likely to tell others.
Professional services
Word of mouth is crucial for professional services such as real estate agents, consultants, and freelancers. Clients who have had a positive experience will be more inclined to recommend their service provider to friends and colleagues.
Retail & E-commerce
Shops selling unique or handmade products can benefit greatly from word of mouth, particularly if their products stand out on social media. Hobby shops and niche retailers can also build loyal customer communities that naturally generate recommendations.
Fitness, health & wellness
Gyms, personal trainers, and wellness businesses see significant benefits from WOMM. People are more likely to join a gym or try a new fitness class if they hear about it from a friend who had a positive experience.
Examples of successful word of mouth marketing campaigns UK
Wild Cosmetics
Wild Cosmetics specialises in refillable deodorants and body care products aimed at reducing single-use plastics. The brand’s commitment to sustainability and innovative product design resonated with consumers, leading to organic discussions and recommendations. This positive word-of-mouth contributed to a 77% revenue increase, reaching £46.9 million in 2023, and culminated in the company’s acquisition by Unilever for nearly £100 million in April 2025.
Wingstop UK
In 2018, entrepreneurs Tom Grogan, Herman Sahota, and Saul Lewin introduced the American chicken wing franchise Wingstop to the UK. The brand rapidly gained popularity, particularly among Gen Z consumers, thanks in part to endorsements from celebrities like Stormzy and AJ Tracey. These endorsements and the ensuing buzz led to organic word-of-mouth promotion, fuelling the expansion to 50 restaurants across the country and resulting in the company’s sale for over £400 million in December 2024
