I've spent a lot of my career thinking about marketing.
How do we get someone's attention? What message will make them click? Which offer will convert? How do we get more people into the funnel?
Those questions still matter, and I don't think they're going away anytime soon, but lately I've found myself thinking about a different question.
What if some of the most valuable marketing happening around a business isn't actually coming from the business?
Think about the last time you bought something because someone you trusted recommended it.
Maybe you were talking to a friend, reading through a conversation in a group, or asking people who share the same hobby which product they use.
That's the interesting thing about word-of-mouth marketing.
It isn't simply about getting customers to tell other people about your product. At its most powerful, it's about creating an environment where people can share experiences, answer questions, and help one another make decisions.
And increasingly, those conversations are happening inside communities.
What Is Word-of-Mouth Marketing?
Word-of-mouth marketing is when customers share their experiences, opinions, recommendations, or knowledge about a product or brand with other people.
It can happen in a conversation between friends. It can happen in a product review, social media post, group chat, or online community. It can even happen when one customer answers another customer's question.
The important part is that the information is coming from someone with firsthand experience rather than directly from the company.
That distinction matters.
A brand can tell you that a product is easy to use.
A customer can tell you, "I set it up in about 20 minutes, and here's the one thing I wish I'd known before I started."
Those are two very different kinds of information.
Research continues to show the influence of peer recommendations and online communities on consumer decisions. Recent research from Clutch found that 98% of consumers who regularly participate in online communities trust product or service recommendations from other community members.
We probably don't need a statistic to understand why.
We've all experienced it. We've Always Trusted Other People.
Word of mouth obviously isn't new. Businesses have grown through recommendations for as long as businesses have existed.
What's changed is the scale.
Twenty years ago, you might ask a neighbor which lawn mower they owned or a coworker where they bought their running shoes. Today, you can ask the same question inside a community with thousands of people who care about exactly the same thing you do. And you don't necessarily need to know them personally for their experience to be useful.
If you've spent six months in a community, you start recognizing people. You know who gives thoughtful answers. You know who has actually used the products they're talking about. You also know who seems to recommend whatever they bought last week.
That context matters because recommendations aren't all equal.
Trust develops over time.
Once it exists, the person making the recommendation can become far more persuasive than the company selling the product.
Businesses Naturally Want To Control The Message
I understand why businesses spend so much time trying to control how their products are presented. I've done the same thing.
We spend hours writing product descriptions, refining landing pages, creating ads, producing videos, and trying to anticipate every possible objection.
We want the message to be accurate, polished, and persuasive.
Then a customer explains the same product to another customer in two sentences and somehow does a better job.
I think part of the reason is that customers speak from experience rather than positioning.
They don't say, "This product delivers industry-leading performance."
They say, "I bought this six months ago because I had the same problem you're having. Here's what I liked about it, and here's what I didn't."
That's a completely different conversation.
It also contains something marketing copy usually struggles to create: Credibility.
The customer isn't trying to sound like a marketer. They're trying to be helpful.
And that changes how the information is received.
Customers Understand Questions We Don't Always Think To Answer
This is one of the things I find most valuable about watching customers talk to each other.
Businesses know their products incredibly well, but sometimes that actually makes it harder to see them from a new customer's perspective. We know what every feature does, why we built it, and what makes it different from the competition.
A customer may care about something completely different.
They want to know whether it's difficult to set up, if it's worth spending more for one version over another or what somebody wishes they had known before buying it.
Those questions tend to surface naturally in conversations.
And the answers usually come with context that would be difficult to fit onto a traditional product page.
That's one reason customer recommendations can be so useful.
A customer isn't necessarily explaining every feature. They're explaining what actually mattered to them.
The Conversation Doesn't Have To Be Positive To Be Valuable
This is where I think community can make businesses a little uncomfortable.
If customers are talking freely, we're not going to control everything they say.
Someone might dislike a feature. Another person might recommend a competitor's product for a particular situation. People are going to disagree.
My instinct earlier in my career probably would have been to see that as a problem.
I'm not sure I do anymore.
If every conversation inside a brand's community somehow ends with the company's product being the perfect answer, people are going to figure out pretty quickly that the conversation isn't genuine.
Real customers have opinions. They have different needs and different budgets. Sometimes your product genuinely isn't the best choice for someone.
Allowing those conversations to happen naturally can make the recommendations that do happen more credible.
Trust isn't created because everyone agrees.
Trust is created because people believe the conversation is real.
That matters in an environment where consumers have become very good at recognizing marketing.
A 2026 survey from EMARKETER found that consumers value honest discussion of both the strengths and weaknesses of products when evaluating recommendations.
That's something businesses should pay attention to.
The goal of a customer community shouldn't necessarily be to make every conversation positive. It should be to make the conversations useful.
How Word-of-Mouth Marketing Actually Works
When you break it down, effective word-of-mouth marketing isn't particularly complicated.
1. A customer has an experience: They buy something, use a product, solve a problem, or learn something.
2. They share what they learned: That might happen through a conversation, review, social post, referral, or community discussion.
3. Another customer asks a question: The conversation becomes more useful than a simple recommendation. Instead of "I love this product," someone asks: "Would you recommend it if I'm just getting started?" Now there's an opportunity for a real answer.
4. The answer reduces uncertainty: The prospective customer gets context from someone who has actually been there. They hear what worked. They hear what didn't. They learn what the original customer wishes they had known. That can make a purchasing decision feel less risky.
5. The new customer becomes part of the community: And eventually, something interesting happens. That new customer may become the person answering someone else's question. The cycle continues. That's where word-of-mouth marketing starts becoming something much bigger than a referral. It becomes part of the customer experience itself.
Maybe Marketing Doesn't Always Need To Start With The Brand
Traditionally, businesses create the message and distribute it to customers.
Community changes that dynamic.
A customer can ask a question that the business never anticipated, and another customer can answer it using an experience the marketing team never knew existed. Someone else adds their perspective, another person disagrees, and suddenly you've got a useful conversation that could help hundreds of future customers.
The company didn't create the content.
It created the place where the content could happen.
That's an important distinction.
Research on online brand communities has also found relationships between community engagement and customers' likelihood of leaving product reviews. In other words, participation isn't necessarily separate from customer advocacy; the community itself can help create the conditions for customers to share their experiences.
The more I think about that behavior, the more I wonder whether businesses should spend a little less time trying to create every marketing message themselves and more time making it easier for customers to talk to each other.
This Changes What Community Is Worth
If you look at a community strictly through traditional marketing metrics, it can be difficult to understand its value.
A conversation between two customers may not generate an immediate click. Someone answering a beginner's question may not produce a sale that afternoon. A discussion comparing several products might not fit neatly into an attribution report.
But that doesn't mean nothing happened.
Someone learned something. Someone gained confidence. Someone developed trust in another member.
And six weeks later, that person may make a purchase because of a conversation nobody on the marketing team even remembers.
That's difficult to measure with a last-click attribution model, but it's very easy to understand when you think about how people actually make decisions.
Most buying decisions aren't one click.
They're a collection of small moments that gradually reduce uncertainty.
A customer conversation can be one of those moments.
Sometimes it can be the most important one.
What This Means for Ecommerce Brands
For ecommerce businesses, this creates an interesting opportunity.
The customer journey doesn't have to end when someone clicks "Buy."
What happens after the purchase can influence what happens next.
A customer can ask how to use the product. They can learn about another product that works with it. They can share a result. They can answer a question from someone considering a purchase. They can leave a review. They can recommend the brand to someone else.
That means the traditional ecommerce funnel may be only part of the picture.
Instead of thinking:
Visitor → Customer
We can start thinking:
Visitor → Customer → Participant → Advocate
Not every customer will become an advocate, and they shouldn't have to.
But creating opportunities for customers to learn, share, and help each other can strengthen the relationship long after the original transaction.
That's where community marketing and customer advocacy start to overlap.
The Business Still Has A Role
None of this means the brand should disappear.
In fact, I think businesses have an incredibly important role inside these communities. They can answer questions nobody else can answer, provide expertise, correct bad information, introduce people to one another, and make sure the environment remains useful.
The difference is that the business doesn't have to be the only voice.
That's where I think things get interesting.
Instead of one company talking to thousands of customers, you can eventually have thousands of customers talking to each other.
The business is still part of the conversation, but it no longer has to create every conversation.
From Customer to Advocate
Once customers begin helping each other, sharing experiences, and recommending products, something else starts to happen.
Some of those customers become much more than customers.
They become the people welcoming newcomers.
They answer questions before the company has a chance to respond. They share what they've learned. They explain how they solved a problem. They recommend a product when someone asks for advice.
Eventually, they may become trusted voices inside the community.
That's customer advocacy.
And it doesn't always have to be formal.
You don't necessarily need a complicated ambassador program or a rewards system.
Sometimes advocacy starts with something much simpler:
Give customers a place where being helpful is valuable.
When people have a good experience and an opportunity to share it, some will naturally become advocates.
That's a very different relationship than customer acquisition.
You're no longer simply trying to convince someone to buy.
You're creating the conditions for customers to help other customers.
This is the part of marketing that I find increasingly interesting.
For most of my career, I've thought about marketing as something a business creates and sends out into the world.
- An email.
- An ad.
- A landing page.
- A social post.
- A campaign.
I'm starting to think that's only part of the picture.
The other part is what happens between customers.
- The questions they ask.
- The answers they give.
- The experiences they share.
- The recommendations they make.
- The trust they build with one another.
That's where community becomes more than an audience.
It becomes part of the customer journey.
And once customers begin helping each other, something else starts to happen.
Some of those customers become the people who welcome newcomers, answer questions, share what they've learned, and become trusted voices inside the community.
Eventually, they start helping the business grow without being asked to.
Closing Thought
Sometimes the most persuasive thing a business can do is create an environment where customers can talk honestly with other customers.
You can't completely control those conversations. And that's probably the point.
Because when a recommendation comes from someone who has actually used the product, understands the problem, and has nothing to gain from making the recommendation, people tend to listen.
Maybe the future of word-of-mouth marketing isn't getting more people to talk about your brand. Maybe it's creating a place where your customers can talk to each other.
