Customer Effort Score (CES)
A metric that measures how easy or difficult it is for customers to interact with your brand—whether that's getting support, making a purchase, or resolving a problem. It's typically measured on a simple scale (like 1-5 or 1-10) and directly correlates with customer loyalty and lifetime value.
Full Explanation
The core problem CES solves is this: companies often focus on whether customers are satisfied, but they miss the bigger picture—effort. A customer might be satisfied with a product but frustrated by a painful support process. Research shows that reducing customer effort is actually more predictive of loyalty than satisfaction alone.
Think of it like this: imagine two restaurants. Restaurant A has amazing food but a confusing reservation system. Restaurant B has good food and a simple, one-click reservation process. You'll return to Restaurant B more often, even if the food isn't quite as good. CES measures that friction.
In marketing and customer success tools, CES typically appears as a post-interaction survey question: "How easy was it to resolve your issue?" or "How easy was it to complete your purchase?" The answers are aggregated into a score. AI-powered systems now analyze the text behind those scores to identify which specific processes or touchpoints are creating friction.
For CMOs, CES matters because it directly impacts customer acquisition costs and retention budgets. High effort scores correlate with churn, negative word-of-mouth, and reduced lifetime value. When you're evaluating AI tools for customer service, marketing automation, or commerce, CES should be a key metric you track before and after implementation. A tool that improves CES by even 10 points can reduce support costs by 15-20% while increasing repeat purchase rates.
Why It Matters
CES is a leading indicator of customer loyalty—often more predictive than satisfaction scores. This matters because loyal customers cost less to serve, buy more frequently, and generate positive word-of-mouth. For budget-conscious CMOs, improving CES is one of the highest-ROI investments you can make: reducing effort in key customer journeys directly lowers churn and increases lifetime value.
When selecting AI tools, CES should be a core evaluation metric. Ask vendors: "How will this tool reduce customer effort in our key journeys?" Tools that lower CES typically show 15-25% improvements in retention rates and 10-20% reductions in support costs. Additionally, CES data reveals which AI implementations will have the fastest payback period—focus on automating the highest-effort touchpoints first.

Sentiment Analysis
AI technology that reads text and automatically determines whether the tone is positive, negative, or neutral. It's like having a team of people reading every customer comment, review, and social post to tell you how people actually feel about your brand—but instantly and at scale.
Customer Success
A business function focused on ensuring customers achieve their desired outcomes while using your product or service. Unlike customer support (which fixes problems), customer success proactively helps customers get value and reach their goals. For marketing leaders, it's the bridge between acquisition and retention that directly impacts revenue and brand advocacy.
Net Promoter Score (NPS)
A single-number metric that measures customer loyalty by asking one simple question: 'How likely are you to recommend us to a friend?' Customers rate you 0-10, and the score tells you whether your brand is growing or shrinking based on word-of-mouth.
Customer Satisfaction Score (CSAT)
A metric that measures how satisfied customers are with your product, service, or specific interaction, typically on a numerical scale. CMOs use CSAT to track whether marketing promises match actual customer experience and to identify where AI-driven improvements can have the biggest impact.
