How to design customer satisfaction surveys

Updated
Customer satisfaction surveys are one of the easiest ways to get insights straight from the source: your customers. And they're incredibly popular—about 80% of companies actively use these surveys to see how they're doing and make improvements. Why? Because happy customers tend to stick around, spread the word, and drive growth. These surveys give you a front-row seat to understand what your customers love, what they don't, and what you can do to keep them coming back. When you make it clear that you're listening and committed to improvement, you gain valuable insights, strengthen relationships, and foster loyalty.

Why are customer surveys important?

Understand customer needs and expectations: Customer surveys offer direct insight into what customers value most, highlighting their needs and expectations. This feedback allows you to shape products or services around customer preferences, driving satisfaction and loyalty.

Pinpoint areas for improvement: Surveys reveal specific pain points that may go unnoticed otherwise. When customers share what frustrates or delights them, you can make targeted improvements, enhancing their experience and satisfaction over time.

Build trust and engagement: By asking for feedback, you show customers that their opinions matter. This involvement strengthens relationships and can boost retention, as customers feel valued and more connected to the brand.

Types of questions

Different question types serve various purposes in a customer satisfaction survey. Here's a breakdown:

Binary Scale (Yes/No)

Binary questions are perfect when you need quick, straightforward feedback. They work well when seeking a clear answer, such as confirming whether a specific need was met. For instance, "Did our product meet your expectations?" quickly captures satisfaction without overwhelming the respondent. Binary questions are ideal for early-stage surveys or follow-up questions within longer surveys to maintain focus.

Likert Scale (Strongly Disagree to Strongly Agree)

Likert scales allow respondents to indicate varying levels of agreement with a statement, which helps in understanding nuanced attitudes. Statements like "I am satisfied with the support provided" can reveal not just agreement but also intensity, showing whether respondents feel mildly or strongly about the topic. This is best used in feedback surveys where attitude toward certain services, interactions, or product features is valuable.

Rating Scale (1–5 or 1–10)

Rating scales are ideal when you need a more granular understanding of satisfaction, particularly with specific aspects of a product or service. Asking customers to rate their experience on a scale of 1–10 can show subtle differences in satisfaction. This method is often used in Net Promoter Score (NPS) and Customer Satisfaction (CSAT) surveys because it gives a range that can be easily averaged and tracked over time for trends.

Multiple Choice (MCQ)

MCQs offer predefined options, making it easy to analyze responses. They are particularly useful when you want respondents to choose from a set of specific answers, such as identifying which feature of a product they value most or selecting a category that best describes their use case. This format also works well for gathering demographic or user profile information.

Open-Ended Questions

These questions allow respondents to elaborate in their own words, which can provide valuable insights into specific areas for improvement. For example, "What could we improve about our product?" gives customers a chance to highlight particular concerns or suggestions. Open-ended questions are best used sparingly within surveys due to the time and effort they require from respondents and are often most effective toward the end of a survey.

Dropdowns

Dropdown questions work well for filtering responses or collecting categorical information without overwhelming the respondent with options. They're ideal for demographic information, such as selecting a country of residence, age range, or preferred product model. Dropdowns streamline survey experiences by keeping options organized, especially when there are numerous potential answers.

Matrix Questions

Matrix questions allow respondents to evaluate multiple items using the same response options, which can be useful for comparing different aspects of a product or service. This format is most useful in surveys that cover several service dimensions, as it reduces the survey length while capturing detailed feedback on various features.

How to measure customer satisfaction

Net Promoter Score (NPS)

NPS asks a single question:

Respondents answer on a scale from 0 to 10, where:

The NPS score is calculated by subtracting the percentage of Detractors from the percentage of Promoters:

NPS = %Promoters − %Detractors

For example, if 100 respondents include 60 Promoters, 25 Passives, and 15 Detractors, the calculation is 60% − 15% = 45. An NPS can range from -100 to +100.

Customer Satisfaction Score (CSAT)

Customer Satisfaction Score (CSAT) is a straightforward metric used to measure customer satisfaction with a specific product, service, or interaction. It typically asks customers to rate their satisfaction on a 1-5 scale (1 being very dissatisfied and 5 being very satisfied) or sometimes a simpler 1-3 or 1-10 scale. The question is often phrased as: "How satisfied were you with your recent experience?". CSAT is expressed as a percentage, with higher scores indicating better satisfaction.

CSAT(%) = Number of satisfied customers (4s and 5s) / Total number of responses​ × 100

Customer Effort Score (CES)

CES measures how easy or difficult it was for customers to accomplish a task, such as resolving an issue with customer support. Customers are asked to rate on a 5- or 7-point scale. One of the simplest ways to measure CES is by calculating the average score from responses

CES (Average) = Sum of all CES scores / Total number of responses

For example, on a scale of 1-10, if 200 customers respond and their scores add up to 1,600, the CES is 8 out of 10, which shows customers found things fairly easy. Another method works well for binary scales like Agree/Disagree or Happy/Unhappy faces. Here, you subtract the percentage of negative responses from the positive ones. For instance, if 500 people respond, with 300 positive and 200 negative, you’d calculate 60% positive minus 40% negative, giving you a CES of 20%

How to use survey results

After collecting survey data, it's essential to analyze the findings and translate them into meaningful actions.

When to use customer satisfaction surveys

Customer satisfaction surveys are most effective when the customer experience is fresh in their mind, ensuring you get honest and relevant feedback. Conduct surveys regularly, whether daily, weekly, or monthly, to track satisfaction over time. Use various channels like email, in-app prompts, and phone calls to reach customers. However, avoid overwhelming customers by sending surveys too frequently, as this can lead to survey fatigue and lower response rates. To gather actionable insights, tie customer satisfaction surveys to different stages of the customer journey:

Best practices for customer satisfaction surveys

  1. Keep it focused: Respect your customers' time by keeping surveys concise. Focus on key questions that provide actionable insights.
  2. Use simple language: Avoid jargon to ensure all respondents understand the questions and can answer accurately.
  3. Integrate surveys into the customer journey: Embed surveys at natural touchpoints within the customer experience, such as during onboarding, post-purchase, or post-support interactions, for higher engagement rates.
  4. Timing matters: Send surveys promptly after key interactions or touchpoints to capture relevant, real-time feedback.
  5. Make surveys mobile-friendly: Many customers may access your survey from mobile devices. Ensure it’s optimized for mobile to provide a smooth, seamless experience for all respondents.
  6. Avoid leading questions: Leading questions can bias responses by suggesting a certain answer. Make sure your questions are neutral to capture honest, unbiased feedback.
