Happy customers don’t just stick around, they tell others about their experiences. In fact, after 70% of interactions, people say they’re somewhat or very likely to recommend a business to friends and family. That kind of advocacy doesn’t happen by accident. It starts with knowing how your customers feel about your brand and the products and services it provides.
That’s where understanding what a customer satisfaction survey is comes in. These surveys help you better understand the customer experience, learn what’s going well, and where your brand can improve.
But let’s be honest, creating a customer satisfaction survey that gets real, useful feedback? That’s not always straightforward and easy. What are the right questions to ask? How is it best to reach out? And when is the right time to collect feedback?
In this guide, we’ll walk you through how to measure customer satisfaction survey results, what questions to ask, and how to use those insights to take smarter action. In addition, we’ll explain how Trengo helps you collect, track, and respond to feedback.
What is customer satisfaction?
Customer satisfaction is a measure of how well your business meets, doesn't meet, or exceeds customer expectations. It reflects what people hoped for and what they actually experienced when interacting with your product, service, or team.
When satisfaction is high, it often leads to repeat sales, brand loyalty, and positive word of mouth. When it’s low, customers may quietly churn, and you might not know why until it’s too late.
That’s why knowing what a customer satisfaction survey is and how to use it is so important. These surveys give you a direct way to access what your customer is really thinking. They help you understand if you're delivering value where it counts, and where things aren't delivering what customers expect.
Satisfaction insights can do more than improve your support. They can also guide product development, influence marketing decisions, and inform overall strategy. In other words: customer satisfaction isn’t just a CX metric, it’s a business-critical one.
Why should you measure customer satisfaction?
Customer satisfaction reveals how well your business is really performing. When you measure satisfaction well, you discover where your service is doing well and helping you grow, and where it’s holding you back.
Understanding how to measure customer satisfaction survey results helps you make smart, strategic improvements across your business. From frontline support to product design, there are so many areas of your business that can benefit from a customer satisfaction survey. Here’s why it’s worth doing right.
Loyalty becomes stronger
When people feel heard, they are more likely to stick around. Measuring satisfaction helps you demonstrate to your customers that you care what they think and listen to what they have to say. When you then act on what you hear, that builds trust.
Loyal customers tend to be more forgiving, more engaged, and more likely to choose your brand time and time again. And the more connected they feel to your brand, the less likely they are to leave over price alone. Emotional loyalty leads to consistent revenue, and in many cases, long-term advocacy.
Churn goes down, revenue goes up
Dissatisfied customers rarely complain. Most just stop buying. If you’re not measuring satisfaction, you’re missing out on warning signs.
Learning how to conduct customer satisfaction survey research allows you to catch problems before they lead to churn. And the gains are measurable: McKinsey has published work showing that companies that focus on improving the experience of existing customers often achieve “breakthrough growth” from that core base.
Experience beats price
In a price-sensitive world, experience is your advantage. A smooth, respectful, human customer journey often outweighs a small price difference.
According to Merkle, 66% of people say they care more about experience than cost when making brand decisions. And when times are tough, that margin for error shrinks. If your experience doesn’t justify the price, customers won’t hesitate to look elsewhere.
That’s why knowing how to do a customer satisfaction survey and act on the results is so important. It helps you stay competitive, even when budgets are tight.
Word of mouth drives real sales
Word of mouth is a powerful marketing tool and it starts with satisfied customers. People trust recommendations from their friends and family more than any ad.
According to Wisernotify, personal referrals influence around 13% of consumer sales. But customers only become advocates when they feel genuinely happy with their experience.
If you want more people talking about your brand in a good way, you need to understand what is the importance of customer satisfaction surveys and how to use it to create consistently positive experiences.
Key customer satisfaction metrics to track
If you’re learning how to measure customer satisfaction survey results, you’ll quickly discover there’s no single “magic number.” Satisfaction is complex. It’s shaped by moments across the customer journey rather than by more fixed metrics like website traffic or number of sales.
That’s why businesses track multiple customer satisfaction metrics. Together, these give you a balanced view of how customers experience your brand. Below are the most important KPIs and feedback methods to build into your measurement strategy.
Customer Satisfaction Score (CSAT)
What it measures:
CSAT reflects how satisfied customers are with a specific interaction, product, or service. It’s the most direct way to answer the question: “Did we meet your expectations at this moment?”
How it works:
A customer satisfaction survey asks customers to rate their experience, usually on a 1–5 scale (1 = very unsatisfied, 5 = very satisfied). To calculate CSAT, count the percentage of customers who gave you a 4 or 5.
Example:
If 80 out of 100 respondents give you a 4 or 5, your CSAT is 80%. This tells you 8 in 10 customers were satisfied with their experience.
Why it matters:
CSAT is simple, fast, and actionable. You can attach it to individual touchpoints—like a support ticket or purchase flow—and immediately spot where things go right or wrong.
Pro tip with Trengo:
Send CSAT surveys automatically through WhatsApp, email, or live chat right after an interaction. The responses flow back into Trengo’s inbox, giving your team a clear view of satisfaction by channel.
Net Promoter Score (NPS)
What it measures:
NPS gauges loyalty by asking one question: “How likely are you to recommend our company to a friend or colleague?” Customers answer on a scale of 0–10.
How it works:
- 9–10: Promoters (loyal advocates)
- 7–8: Passives (neutral)
- 0–6: Detractors (unhappy)
To calculate your NPS, subtract the percentage of detractors from the percentage of promoters.
Example:
If 70% are promoters and 10% are detractors, your NPS is +60.
Why it matters:
NPS gives you a clear signal of long-term loyalty. Unlike CSAT, which measures one interaction, NPS captures overall brand perception.
Pro tip with Trengo:
Because NPS surveys can be embedded in customer conversations, you don’t have to push people to a different platform. This makes it easier to collect honest, quick feedback.
Customer Effort Score (CES)
What it measures:
CES reveals how easy (or difficult) it is for customers to get something done. That could be something like resolving a problem, completing a purchase, or navigating your product.
How it works:
Customers rate their effort on a scale (e.g., 1 = very difficult, 5 = very easy). Average the scores to get your CES.
Example:
If 100 customers give you an average score of 4.2, that means most customers found the experience easy.
Why it matters:
Effort is a strong predictor of loyalty. Customers are more likely to stay loyal when it’s easy to do business with you.
Pro tip with Trengo:
Track CES in support channels. If customers report high effort resolving tickets, you can identify where there are bottlenecks and automate simple tasks with Trengo’s Flowbot.
Customer feedback surveys
While CSAT, NPS, and CES give you scores, sometimes numbers aren’t enough. Open-text surveys let customers explain their experience in their own words. They reveal context, nuance, and ideas for improvement.
Common feedback surveys include:
- Customer experience surveys: Check if you’re meeting needs across the journey. These could be run every 3 to 6 months.
- Customer service feedback surveys: Assess support quality, from response times to empathy. Send these after support interactions.
- Onboarding satisfaction surveys: Capture impressions from new customers and refine your welcome process. Send these after a new customer is onboarded
- Brand performance surveys: Ask about perceptions of quality, design, or price versus competitors. These could be run every 3 to 6 months.
- Customer analysis surveys: Used in B2B to understand clients’ end-customers and market needs. These could be run every 6 months.
Why it matters:
Feedback surveys go beyond numbers. They help you understand why scores look the way they do and what actions to take to improve them.
Online reviews
Online reviews are one of the most visible forms of feedback, where not only your team, but also potential customers will see what is being said. Customers often leave reviews when they’re very happy, or very frustrated.
How to use them:
- Spot recurring complaints or compliments.
- Track sentiment over time.
- Identify product or service gaps competitors might exploit.
Pro tip with Trengo:
Use social listening integrations to track reviews and mentions across multiple platforms. You’ll see trends without switching between tools.
Customer complaints
No business loves complaints, but they’re very helpful for identifying where customer service or a product can be improved. Complaints are direct signals of where you’re not meeting expectations.
Best practices:
- Collect complaints across all channels, not just email or reviews.
- Respond quickly to show you’re listening.
- Follow up to confirm the issue is resolved.
Why it matters:
Addressing complaints quickly helps to solve the issue fast as well as builds trust and show commitment. In some cases, a well-handled complaint can turn a critic into a promoter.
Putting it all together
The most effective approach isn’t choosing between CSAT, NPS, CES, or feedback surveys. It’s combining them. Together, they give you a holistic view of satisfaction: the quick pulse (CSAT), the big-picture loyalty check (NPS), the ease of experience (CES), and the detailed story (feedback and reviews).
With Trengo, you can centralise these insights in one inbox. Surveys, reviews, and complaints link back to customer profiles, giving your team a 360 view of every relationship. That means you don’t just measure satisfaction, you act on it.
How to measure customer satisfaction survey
Knowing how to measure customer satisfaction survey results turns customer feedback into real business insight. A survey when well executed and data well collected gives you a chance to listen, learn, and take smarter action. Here’s how.
Define your goal
Start by deciding what you want to learn. Are you measuring loyalty, testing a new product, or checking support quality? Clear goals help to keep your survey focused and avoid going on tangents or asking questions that don't relate to what you really want to find out.
Choose the right survey type
Different surveys answer different questions:
- CSAT > Are customers satisfied with this interaction?
- NPS > Will customers recommend us long term?
- CES > Was the experience easy or difficult?
If you’re new to how to conduct customer satisfaction survey research, start with one type and expand from there.
Decide how to ask for customer satisfaction survey responses
Timing and channel matter.
- After interactions: Send a CSAT survey after support or purchase.
- Regular check-ins: Use NPS quarterly to measure loyalty.
- Within conversations: Ask in WhatsApp, email, or chat to keep it simple.
Trengo makes this easy—surveys can be sent directly in the channels customers already use.
Write clear, simple questions
Keep surveys short and easy to answer. Examples of what questions to ask in a survey for customer satisfaction:
- How satisfied were you with your experience today?
- How likely are you to recommend us?
- How easy was it to resolve your issue?
- What’s one thing we could improve?
Two to three questions are usually enough. You don't want to overwhelm your customer.
Set up and send your survey
Pick your tool, set your channel, choose timing, and test before sending. With Trengo, you can set up a customer satisfaction survey that’s linked directly to your customer inbox, making results part of the conversation.
Analyse the results
Look at scores and patterns, but also read open comments to understand the “why.” Segmenting by product, team, or channel helps reveal where improvements are most needed.
Share your insights and take action
Share results across teams. Support, product, and marketing all benefit from customer feedback. Then look at how you can fix recurring issues, follow up with unhappy customers, and encourage happy ones to leave reviews.
This is also how to improve customer satisfaction surveys: when customers see you acting on feedback, they’re more likely to respond again.
How to improve customer satisfaction
Running a customer satisfaction survey is just the first step. The real value you get from them comes when you use feedback to improve your product, services and customer relationships. You can use your feedback to reduce friction and deliver better experiences. Here’s how to improve customer satisfaction in a structured way.
Act on survey feedback
Your feedback only has an effect if you actually listen to it and make improvements based on it. The most effective way to improve satisfaction is to listen and show that you’ve done so. Whether the feedback is about slow response times or product usability, customers expect you to act on what they have to say.
- Identify recurring issues and prioritise quick fixes.
- Share feedback across teams, not just support.
- Let customers know when changes are made based on their input. (This doesn’t just solve problems, it builds trust.)
- Focus on the customer journey.
Many businesses only measure satisfaction at single touchpoints. But customers think in journeys, not transactions. By linking survey insights to the full experience, from onboarding, and purchase to service and renewal, you’ll discover even greater opportunities for improvement.
With Trengo, all conversations and survey results connect to customer profiles. That makes it easier to see where journeys break down and take action fast.
Personalise your interactions
People want to feel recognised and heard, not treated like a ticket number. Personalisation such as using customer history, preferences, or past feedback, goes a long way in helping them feel heard.
A practical step: use survey results to segment customers. For example, follow up with detractors in a more proactive way, while encouraging promoters to leave reviews.
Reduce effort for customers
Ease is often more important to customers than anything. They don't want to experience friction and if it takes too long to get help or complete a purchase, satisfaction drops.
Look at your Customer Effort Score (CES) results to identify where processes are too complex. Then simplify them. This could be through better self-service, automation, or clearer communication.
Train and empower your team
Your people are on the front line of customer satisfaction. You need to give them the training and tools to handle issues quickly and confidently. Empower them to resolve complaints without excessive process and approvals.
When your team feels supported, customers feel they are being heard.
Make improvement continuous
Customer needs evolve. Running surveys once isn’t enough. The key is to build a cycle of measuring, acting, and re-measuring.
This is where the importance of customer satisfaction surveys lies. It creates a feedback loop that fuels ongoing improvement. Each survey gives you a new benchmark, so you can see if changes are actually working.
Final thoughts
A customer satisfaction survey is a way to understand your customers, earn their trust, and build lasting loyalty. When you measure the right metrics, ask thoughtful questions, and act on the feedback, you move from guesswork to strategy.
The importance of customer satisfaction surveys goes beyond customer service. They guide product development, refine your customer journey, and strengthen your overall business performance.
With Trengo, measuring satisfaction becomes part of your daily workflow. Surveys can be sent through WhatsApp, email, or live chat. And because every response links back to a customer profile, your team always has the full picture. That means you’re not just collecting feedback, you’re closing the loop and improving the experience that really matters to your customers.
