What is Customer Effort Score (CES)? Definition & Guide
Customer Effort Score is a metric that measures how much effort a customer had to expend to get their issue resolved, question answered, or task completed. Lower effort scores correlate with higher customer loyalty. CES is measured on a scale from 'very easy' to 'very difficult'.
Understanding Customer Effort Score (CES)
CES is based on the research finding that customer loyalty is driven more by reducing effort than by exceeding expectations. A customer who gets a quick, easy resolution will be more loyal than one who receives an impressive but complex experience. This insight makes CES particularly relevant for evaluating self-service channels like voice AI.
CES is typically measured through a post-interaction survey asking 'How easy was it to [complete task]?' on a 5 or 7-point scale. The metric can be tracked per interaction, per channel, and over time. Organizations compare CES across channels — phone, chat, email, self-service, voice AI — to identify which channels provide the easiest experience.
Voice AI has the potential to dramatically reduce customer effort. Instead of navigating complex websites, waiting in phone queues, or typing detailed descriptions, visitors simply speak their need. AnveVoice's combination of voice interaction, agentic website navigation, and instant response addresses the key effort drivers: time, complexity, and channel switching.
