The Best Way to Grow Your Business (No One’s Talking About)

Most business growth strategies focus on acquiring new customers: ads, campaigns, discounts, and outbound sales. But the most powerful, cost-effective growth engine is already sitting in your customer base and most companies completely overlook it.

When I worked in SaaS, we captured the source of sign-ups and fairly consistently, 10% reported word-of-mouth. Additionally, we would get responses all of the time from customers raving about us in various Facebook groups. It's worth paying attention to this, I'm telling you this is a huge growth lever.

The secret is Customer advocacy.

What Is Customer Advocacy?

Customer advocacy happens when your clients actively champion your business. They recommend you to friends, defend your brand online, share their positive experiences, and influence others’ purchasing decisions.

It’s important to note that not all satisfied customers are advocates. Advocacy requires a deeper connection: your customers need to feel seen, heard, and confident that your business consistently delivers value. Companies that cultivate advocacy don’t just keep customers, they turn them into partners in growth.

Why Measuring Advocacy Matters

Customer advocacy isn’t a “nice-to-have”, it’s a growth imperative. Advocates:

• Reduce marketing costs by spreading word of mouth
• Increase conversion rates because referrals carry credibility
• Help identify product improvements through feedback
• Strengthen your brand reputation in competitive markets

Without measurement, advocacy is guesswork. You may think your customers are happy, but without data, you can’t reliably identify your promoters or understand their motivations.

Core Metrics to Track

A strong advocacy strategy relies on quantitative and qualitative metrics. Here’s what matters most:

1. Net Promoter Score (NPS)

NPS is a simple yet powerful gauge of customer loyalty. It measures how likely a customer is to recommend your company to others. Respondents are grouped into three categories:

• Promoters (9–10): Highly loyal and likely to refer others
• Passives (7–8): Satisfied but unlikely to actively promote
• Detractors (0–6): Unhappy customers who could harm your reputation

Tracking NPS over time allows you to see trends in loyalty, measure the impact of changes, and identify areas where interventions could convert passives or detractors into promoters.

2. Customer Satisfaction (CSAT)

CSAT measures immediate satisfaction with a product, service, or interaction. Unlike NPS, which gauges long-term loyalty, CSAT gives insight into specific touchpoints in the customer journey.

Why it matters:

• It highlights pain points before they escalate into churn
• It signals where operational improvements are most needed
• It provides actionable data for support teams and product managers

3. Support Team Metrics

Your support team plays a crucial role in turning satisfaction into advocacy. Metrics to track include:

• Response times: How quickly customers get a first reply
• Resolution rates: How often issues are fully resolved
• Follow-ups: Whether customers feel supported throughout the process

A fast, empathetic, and effective support experience strengthens customer trust and increases the likelihood of referrals. Advocacy often starts with a problem being solved the right way.

4. Additional Customer Metrics

Beyond NPS and CSAT, consider tracking:

• Retention and repeat purchase rates: Customers who return frequently are more likely to advocate for you.
• Engagement metrics: Participation in surveys, webinars, or community forums can indicate enthusiasm.
• Customer feedback frequency and quality: Customers who provide thoughtful suggestions often become your most vocal promoters.

Tracking multiple metrics together gives a holistic view of your customer relationships, helping you identify trends, risks, and opportunities for advocacy.

Turning Metrics Into Advocacy

Measurement alone isn’t enough. You must act on the data:

1. Identify your promoters. These customers are your natural advocates. Engage them directly, thank them, and make it easy for them to spread the word. You can develop programs for referrals. We would typically pay 20% per active account referred and activated. I've seen other companies pay $200 and then post about you on social. The $200 is less than the cost to acquire for many and these are definitely more qualified leads so it can make a lot of sense.
2. Address detractors proactively. Turn frustration into loyalty by resolving issues quickly and showing responsiveness.
3. Use insights to improve experiences. If metrics reveal repeated friction points, take action to enhance your product, service, or support processes.
4. Celebrate advocacy publicly. Share testimonials, case studies, or success stories to reinforce a culture of advocacy internally and externally.

By linking metrics to action, you create a self-reinforcing cycle: happy, loyal customers provide referrals, which drive growth, which improves your ability to serve them better.

Why Advocacy Drives Growth

Customer advocates are the most effective form of marketing your business can have:

• They influence peers more effectively than ads or content marketing
• Their endorsements carry credibility that paid campaigns can’t match
• They provide continuous feedback loops that enhance your product or service

A single satisfied, loyal advocate can influence dozens or even hundreds of potential customers. Multiply that across your customer base, and you have a powerful, scalable growth engine without increasing your marketing spend.
