10 Metrics Every eCommerce Brand Should Track

In the world of eCommerce, metrics are essential. They serve as a window into consumer behaviour, campaign performance, and overall business health. Without an eye on key performance indicators (KPIs), even the most promising eCommerce venture may find itself directionless, struggling to make informed decisions. Here, we explore ten fundamental metrics every eCommerce brand should be tracking. By regularly monitoring these KPIs, brands can fine-tune their marketing strategies, improve customer experience, and drive greater revenue.


1. Conversion Rate

Conversion rate measures the percentage of website visitors who complete a desired action, usually a purchase. This metric is central to understanding how effectively your site turns browsers into buyers. Calculated by dividing the number of conversions by the total number of visitors, it reflects the efficiency of the entire customer journey. A low conversion rate may signal issues with site usability, checkout processes, or product appeal.


2. Average Order Value (AOV)

Average Order Value reveals the average amount each customer spends per transaction. To calculate it, simply divide the total revenue by the number of orders. Increasing AOV can have a substantial impact on revenue without needing to acquire additional customers. Brands can boost AOV through techniques like cross-selling, bundling products, or offering free shipping thresholds.


3. Customer Lifetime Value (CLV)

Customer Lifetime Value estimates the total revenue a business can expect from a single customer throughout their relationship with the brand. CLV is a critical metric for understanding customer loyalty and profitability. Calculated by multiplying average purchase value, frequency, and customer lifespan, a high CLV indicates that your retention efforts are effective and customers are happy with their experience.


4. Bounce Rate

Bounce rate is the percentage of visitors who leave a site after viewing only one page. A high bounce rate suggests that the landing page failed to engage the visitor, which could be due to slow loading times, poor design, or irrelevant content. By optimising product pages and ensuring that ads lead to relevant landing pages, brands can reduce bounce rates and encourage users to explore further.


5. Cart Abandonment Rate

Cart abandonment rate tracks the percentage of shoppers who add items to their cart but leave without completing the purchase. For eCommerce businesses, this can be one of the most frustrating metrics, as it indicates lost potential revenue. Reasons for high abandonment rates include unexpected shipping costs, complicated checkout processes, and lack of payment options. Retargeting emails or offering incentives can help recover these abandoned carts.


6. Email Open and Click-Through Rates

Email marketing remains a powerful tool for eCommerce, and monitoring email open and click-through rates can reveal how effective your campaigns are. Open rates show how many recipients viewed your email, while click-through rates indicate the percentage who engaged with the content by clicking a link. Low rates might suggest that subject lines or call-to-actions need improvement. A/B testing different elements in your emails can help determine what resonates best with your audience.


7. Return on Ad Spend (ROAS)

Return on Ad Spend measures the revenue generated per dollar spent on advertising. A key metric in paid marketing, ROAS allows brands to assess the profitability of their ad campaigns. Calculated by dividing the revenue generated by the ad spend, a high ROAS indicates that a campaign is delivering value, while a low ROAS might mean the ad targeting or creative approach needs refinement.


8. Customer Retention Rate

Customer Retention Rate tracks the percentage of customers who continue to make purchases over a set period. This metric is valuable for assessing loyalty and brand satisfaction. A high retention rate signifies that customers are pleased with the products and experience, while a low retention rate suggests that improvements are needed in areas like product quality, customer service, or engagement. Customer loyalty programmes and personalised experiences are effective strategies for improving retention.


9. Net Promoter Score (NPS)

Net Promoter Score is a customer satisfaction metric that measures how likely customers are to recommend your brand to others. Calculated through a simple survey question (“On a scale from 0 to 10, how likely are you to recommend us to a friend or colleague?”), NPS categorises respondents as promoters, passives, or detractors. A high NPS indicates strong brand loyalty, while a low score can signal issues that require attention. Tracking NPS over time provides insights into long-term customer satisfaction trends.


10. Website Traffic and Source Breakdown

Website traffic is the volume of visitors to your site, and source breakdown details where they are coming from, such as organic search, paid ads, social media, or email campaigns. This metric is crucial for understanding how well your marketing channels are performing and where to focus future efforts. By analysing traffic sources, eCommerce brands can determine which channels are most effective at driving quality traffic and which may require further investment.


In Summary

For eCommerce brands, data is the key to growth. These ten metrics—Conversion Rate, Average Order Value, Customer Lifetime Value, Bounce Rate, Cart Abandonment Rate, Email Open and Click-Through Rates, Return on Ad Spend, Customer Retention Rate, Net Promoter Score, and Website Traffic—serve as invaluable guides in navigating the complexities of the online marketplace.

Regularly monitoring these KPIs enables eCommerce brands to identify opportunities, spot challenges, and make well-informed decisions. By focusing on these metrics, brands can refine their marketing strategies, enhance customer experience, and ultimately drive long-term profitability. In a competitive and ever-evolving digital world, data-driven insights are the foundation of eCommerce success.
