Why are They So Happy? Tracking Enthusiasm as a Critical E-Commerce CX KPI

Building enthusiasm in the context of e-commerce CX is not just about satisfying customers — it’s about delighting them. It’s the difference between a customer who makes a one-off purchase and one who becomes a vocal advocate for the brand. This heightened level of engagement and positive emotional response can significantly influence customer loyalty and, in turn, the overall performance and reputation of e-commerce businesses.

The significance of tracking enthusiasm as a KPI reflects an evolving ecommerce landscape where a deeper understanding of customer-brand relationships requires more experiential and emotion-driven indicators​​​​​​. This evolution mirrors changing consumer behavior — as purchasing decisions are increasingly influenced by the emotional connection and experience a brand offers.

In this 5-minute read we’ll explore:

  • What “enthusiasm” means in terms of ecommerce CX
  • The KPIs that can reveal how enthusiastic customers are
  • Strategies to build and maintain customer enthusiasm
  • The importance of the “human factor” in building enthusiasm
  • The future of enthusiasm as a CX indicator and differentiator

The value of customer enthusiasm for e-commerce brands

Customer enthusiasm in e-commerce refers to the level of excitement and satisfaction that customers exhibit towards a brand or product — which translates into measurable outcomes including repeat purchases, positive online interactions, and word-of-mouth recommendations.

For brands, enthusiasm is a crucial factor in building success and longevity. When customers are enthusiastic, they are more likely to have a deeper emotional connection with the brand, leading to higher levels of loyalty and advocacy. This is particularly relevant in e-commerce, where the competition is just a click away — and a customer’s enthusiasm can be the deciding factor between choosing one brand over another.

Statistics published by Forbes underline the importance of fostering customer enthusiasm for a brand, with 83% of companies that believe it’s “important to make customers happy” experiencing growing revenue — and the importance of acting on customer insights, with 77% of consumers viewing brands more favorably if they seek out and apply customer feedback. The value in tracking and growing customer enthusiasm is therefore clear — but how can ecommerce brands measure and understand it effectively?

Key ecommerce KPIs related to customer enthusiasm

Several “traditional” ecommerce KPIs are relevant to customer enthusiasm — and understanding these indicators in combination is a good starting point for e-commerce businesses looking to accurately gauge and enhance customer enthusiasm as a metric.

Customer Satisfaction Score (CSAT)

This metric measures the extent to which products or services meet or exceed customer expectations. CSAT is typically obtained through customer surveys, where customers rate their satisfaction level on a points or percentage scale. A high CSAT score indicates that customers are satisfied and likely enthusiastic about the brand​​.

Net Promoter Score (NPS)

NPS assesses customer loyalty and the likelihood of customers recommending the business to others. It categorizes customers into promoters, passives, and detractors based on their willingness to recommend the business. High scores in NPS are often indicative of a strong customer base with high enthusiasm about, and loyalty​​ towards, a brand.

Customer Retention Rate (CRR)

CRR shows the percentage of customers that an ecommerce business retains over a defined period. A high CRR suggests that customers are continually choosing the brand over other available options, which can be a sign of sustained enthusiasm for the products or services on offer.

Customer Effort Score (CES)

CES measures the ease with which customers can interact with a business, particularly in resolving issues or accessing services. Lower effort scores are usually correlated with higher customer satisfaction and, subsequently, greater enthusiasm​​.

Customers scoring positively in more than one of these areas can reasonably be expected to display enthusiasm for a brand — and those with generally negative scores may require further engagement to build and maintain their enthusiasm. For a clearer picture of customer enthusiasm though, new measurement and analysis techniques offer deeper insights.

Measuring enthusiasm across touchpoints

Measuring enthusiasm requires a mix of qualitative and quantitative approaches — to capture not just the level of satisfaction, but the intensity and quality of the customer’s emotional engagement with the brand.

Traditionally, the primary method for measuring enthusiasm is through customer surveys — either asking direct questions that score customer satisfaction and likelihood of recommendation, or more open-ended questions to gather feedback on what drives their enthusiasm for a brand, product, or service.

Analyzing customer behavior on the ecommerce website itself can provide additional indicators of enthusiasm. Metrics such as time spent on the site, frequency of visits, engagement with content, and social media interactions offer insights into the customer’s interest and excitement about the brand.

According to a Databox report, 53% of ecommerce brands are using tools such as Google Analytics for this purpose.

Today, advanced sentiment analysis tools, powered by AI, are an increasingly widespread method of tracking enthusiasm. These tools go beyond the limited responses gleaned from customer surveys to analyze reviews, social media posts, support requests, phone or email conversations, and other interactions to assess emotion and enthusiasm more broadly.

Some machine learning algorithms can also use these large datasets to reliably predict future customer behavior based on sentiment analysis — with accuracy of up to 80%, according to one study published in the journal Scientific Reports. As these tools continue to evolve, sentiment-based predictive analysis is likely to become much more central to the operational strategy of ecommerce brands.

Strategies to foster customer enthusiasm

Measuring enthusiasm is one part of the challenge, but the most important question for ecommerce businesses is “How can we generate customer enthusiasm?” Fostering genuine and sustained enthusiasm in e-commerce relationships is complex — requiring a strategic approach that goes beyond simple customer satisfaction to create memorable, engaging experiences that resonate with customers on an emotional level.

Digital marketing guru Neil Patel offers several suggestions for enthusiasm-generating activity, including “risk-removers” like free shipping or returns, social proof such as user-generated image or video content of your products in use, and affiliate influencer networks to encourage the most enthusiastic customers to become part of your sales team, spreading the benefits. Relationship commerce specialists OrderGroove stress the importance of foundational strategies such as building a loyalty program, focusing on delivering exceptional customer service, and nurturing customers with personalized onboarding flows.

Whatever specific actions brands choose to take, what’s important is that the benefits, service, or interactions they offer to build enthusiasm are authentic — genuinely aimed at improving the customer experience, rather than cynically designed for short-term commercial gains. Today’s ecommerce shoppers are well-educated and well-connected — so any strategy seen as an attempt to “buy favor” is likely not only to fail but to be widely discussed on social media or review sites — a worst-case scenario for online brands. Focusing on offering real value first and foremost is the key to success here, allowing the commercial benefits such as increased sales or enhanced reputation to accrue organically over time.

The human factor in maintaining enthusiasm

While technology is vital in tracking customer enthusiasm, understanding and responding to customer enthusiasm requires a human touch that resonates on an emotional level. Training customer service teams to be empathetic and responsive can significantly impact customer enthusiasm — with a focus on personalized interactions where customers feel heard.

For ecommerce businesses in particular, social media provides an ideal platform for informal, humanized interaction with customers. Responding to comments, sharing user-generated content, and engaging in conversations can foster a sense of community and enthusiasm — and visibly acting on customer comments or feedback demonstrates that their opinions are valued and considered.

Outsourcing customer experience management to specialized teams can be an effective strategy for ecommerce brands lacking the time or human resources to interact regularly and consistently with their customer communities. While automation might seem like a more convenient solution, to build genuine enthusiasm, brands need to offer genuine human-to-human interactions.

New developments in customer experience tracking

The landscape of customer experience and enthusiasm tracking in e-commerce is poised for significant evolution. Emerging technologies and changing consumer behaviors are set to redefine how businesses engage with and understand their customers. Artificial intelligence and machine learning will become more sophisticated, offering deeper insights into customer behavior and preferences — enabling even more personalized and predictive shopping experiences, and heightening customer enthusiasm.

Virtual and augmented reality experiences are expected to revolutionize the online shopping experience, offering customers immersive and interactive ways to engage with products, and bridging the gap between online and physical shopping. And as voice-assisted devices become more prevalent, voice commerce is likely to become a more significant part of the e-commerce experience. This development could introduce new ways to measure and enhance customer enthusiasm, such as analyzing voice search patterns and preferences.


The importance of enthusiasm as a CX KPI in e-commerce cannot be overstated — as a critical driver of customer loyalty, advocacy, and retention. The challenges in accurately measuring and enhancing enthusiasm highlight the need for a nuanced approach that balances data-driven insights with empathetic customer engagement.

As businesses consider the strategies and tools available to them, it’s worth considering the value of bringing in external expertise. Partners such as SourceCX offer a tailored blend of advice, support, and practical tools that can help brands of all sizes develop, scale, and execute a successful engagement model to build customer enthusiasm.

By continuously striving to improve the customer experience and adapting to evolving trends as they emerge, e-commerce businesses are well-positioned to not only meet but exceed customer expectations, building a base of highly enthusiastic, highly loyal advocates who will be foundational to their future success.
