Customer advocacy is emerging as one of the most powerful and underutilized growth drivers for businesses today. So what is “customer advocacy” and why does it matter? A simple definition is when customers actively promote your brand, product or service to others. It’s where you build a relationship with loyal customers and encourage them to share positive experiences. It matters because it builds trust, increases loyalty and repeat business, improves your reputation, gives you insights on how to keep improving and powers growth.
Traditional marketing is becoming less effective and customer expectations keep rising so companies that harness the power of advocacy are seeing higher conversion rates, increased loyalty and exponential revenue growth.
Why advocacy is the new competitive advantage
Recent research underscores the profound impact on business performance:
But statistics alone don’t tell the full story. The real power of advocacy is revealed through real-world business results.

Real-world impact: Turning advocacy into growth
At Feedback ASAP, we work with brands across industries to help them unlock the true power of advocacy. Each of the case studies that follow — from auto service, fashion retail and telco retail — is from current national clients operating in highly competitive markets. We survey their customers daily, and these case studies are based on results over the last 12 months. Each survey response averages around 40 words, so the volume of actionable feedback and verbatim comments is substantial.
Here are some real-world examples of how CX-driven advocacy is transforming businesses:
Australian car servicing client case study:
- The top 20% of stores generated 78% of their new customers from advocacy — referrals and reviews — compared to just 32% in the bottom 20% of stores.
- As a result, the top-performing stores achieved a 24% year-on-year higher sales growth.
- The difference? Stores that actively measured and improved customer experience saw a direct impact on their revenue growth.
Australian fashion retailer client case study:
- When all customer experience standards were met, NPS was at an impressive 99, meaning nearly every customer became an advocate.
- However, when just two CX standards were missed, NPS dropped 20% and Average Transaction Value (ATV) plummeted by 16%.
- This proves that consistency in customer experience is critical to driving advocacy and sales.
New Zealand telecommunications client case study:
- A leading telco brand leveraged CX advocacy strategies and achieved 18% growth in NPS in 12 months and 31% increase in add-on rates, demonstrating that advocacy isn’t just about reputation — it directly impacts revenue.
In short, businesses that focus on advocacy can achieve more growth with less effort by leveraging customers as active promoters rather than relying solely on traditional paid acquisition.
From passive feedback to proactive advocacy
Too many businesses treat customer experience (CX) as a measurement exercise rather than a growth strategy. Simply collecting NPS scores or customer feedback is no longer enough — companies must turn passive customers into vocal brand advocates by embedding advocacy into every touchpoint of the customer journey.
The brands that are excelling at advocacy today are those that:
- Identify and track their best advocates. Successful businesses proactively measure and engage with customers who are already promoting their brand.
- Leverage customer feedback to drive action. Feedback should lead to real, front-line improvements that inspire advocacy rather than just sitting in a report.
- Empower teams to deliver exceptional experiences. Employees who feel accountable for CX improvement create stronger customer relationships, which fuels advocacy.
- Integrate advocacy across departments. Advocacy isn’t just a marketing function — it should be a company-wide initiative spanning operations, customer service and HR.

Winning on action: The future of CX is proactive
Fred Reichheld, creator of NPS, highlights in Winning on Purpose that the companies achieving the fastest growth aren’t those collecting the most feedback but those taking deliberate, strategic action based on customer-led improvements.
With over 25 years of experience in 74 countries, leading CX programs for Apple and McDonald’s, we’ve seen firsthand that the future of CX is about more than just measuring loyalty — it’s about engineering advocacy into the DNA of a business.
The new formula for CX growth
Winning brands are moving beyond traditional CX metrics to an end-to-end improvement system that integrates:
- Customer centricity and advocacy: Prioritizing customer success to create loyalty advocates.
- Accountability and motivation: Ensuring teams take ownership of CX-driven growth.
- Action practices and skill development: Empowering teams with real-world behaviors that drive engagement and revenue.
- Embedding best practices and consistency: Aligning operations, marketing and HR to eliminate guesswork and enable continuous improvement.
The evolution of CX: What’s next?
Several key trends are shaping the future of CX:
- Hyper-personalization in CX: Brands are moving away from generic interactions and leveraging AI-driven insights to personalize customer interactions at scale.
- Predictive CX analytics: Companies are using advanced analytics to anticipate customer needs before issues arise, shifting from reactive service to proactive engagement.
- Seamless omnichannel experiences: Customers expect consistent, high-quality interactions across in-store, online and mobile platforms.
- The integration of CX and employee experience (EX): Companies that invest in employee engagement see higher customer satisfaction, reinforcing that happy employees create happy customers.
- The rise of CX-driven revenue models: More businesses are tying CX improvements directly to financial metrics, proving that advocacy and loyalty are key revenue drivers.

Final thoughts
CX is no longer about simply measuring satisfaction — it’s about building advocacy as a strategic asset. Companies that understand this shift and invest in advocacy-driven CX will see higher-value customers, more referrals and organic growth that outpaces competitors. The key to success? Acting on feedback, embedding advocacy into business operations and ensuring every team member is accountable for delivering remarkable customer experiences.
As companies shift their mindset from customer measurement to customer action, those who lead the charge in advocacy will set the new standard for growth in the experience economy.
