Net Promoter Score (NPS) is one of the simplest and most powerful ways to measure how your customers feel about your brand. A single question — “How likely are you to recommend us to a friend or colleague?” — gives you a clear picture of customer loyalty and helps you predict growth. This guide explains how NPS works, how to measure it for your Shopify store, and what to do with the results.
How NPS Works
Customers answer the NPS question on a scale of 0 to 10. Based on their answer, they fall into one of three categories:
- Promoters (9–10): Loyal enthusiasts who will recommend you to others and keep buying.
- Passives (7–8): Satisfied but not enthusiastic. They might switch to a competitor for a better offer.
- Detractors (0–6): Unhappy customers who could damage your brand through negative word of mouth.
Your NPS is calculated by subtracting the percentage of Detractors from the percentage of Promoters. The score ranges from -100 (everyone is a detractor) to +100 (everyone is a promoter).
What Is a Good NPS Score for Ecommerce?
NPS benchmarks vary by industry. For ecommerce:
| NPS Range | What It Means |
|---|---|
| Above 50 | Excellent — strong loyalty, healthy referral potential |
| 20–50 | Good — customers are generally satisfied |
| 0–20 | Average — room for improvement |
| Below 0 | Concerning — more unhappy than happy customers |
For context, top-performing ecommerce brands typically score between 50 and 70. A new store with limited reviews should not panic about a low score — focus on understanding why detractors are unhappy and fixing those specific issues.
How to Run NPS Surveys on Your Shopify Store
Several apps make NPS collection simple on Shopify:
- Fairing — embeds post-purchase surveys on the order confirmation page. You can include NPS as one of several questions.
- Klaviyo — trigger NPS survey emails automatically after a set number of days post-delivery. Results sync back to customer profiles for segmentation.
- Dedicated NPS tools like Delighted or Survicate can also integrate with Shopify via email campaigns.
The best time to survey for NPS is after a customer has received their order and had time to use the product — typically 7 to 14 days post-delivery. Always include an open-text follow-up question: “What is the main reason for your score?” This qualitative data is where the real insights come from.
Acting on NPS Results
NPS data is only useful if you take action. Here is how to use each segment:
- Promoters: Ask them to leave a review, refer a friend, or follow your social media. These people want to help — make it easy for them.
- Passives: Understand what would have made the experience a 9 or 10. Often a small fix (faster delivery, better packaging, clearer instructions) can shift passives to promoters.
- Detractors: Reach out personally to understand their experience. Many detractors who receive a sincere, helpful response become loyal customers. Do not ignore this group.
Track your NPS monthly. A rising score means your improvements are working. A falling score signals a new problem — investigate before it affects revenue. If you want help building a customer experience programme around NPS, the OneOnic team can help.
Frequently Asked Questions
How many responses do I need for my NPS score to be reliable?
A minimum of 30 to 50 responses gives you a directionally useful score. Under 30 responses, random variation can make the score meaningless. Aim to run NPS surveys consistently every month so your sample size grows over time and you can spot real trends.
Should I show my NPS score publicly on my Shopify store?
Only if it is strong (above 50). NPS scores are not as widely understood by general consumers as star ratings are. If you want to display social proof, converting your NPS data into a statement like “9 out of 10 customers recommend us” is more universally understood and makes better marketing copy.
Is NPS the only customer satisfaction metric I should track for my Shopify store?
NPS is a good top-level metric, but pair it with Customer Satisfaction Score (CSAT) for specific interactions (like a support ticket resolution) and Customer Effort Score (CES) to measure how easy your buying process is. Together, these three metrics give a complete picture of your customer experience health.
