Traffic and Acquisition Metrics

The foundation of all digital efforts, ecommerce notwithstanding, begins with a strong foundation of understanding where your visitors, leads, and any other user type come from. In other words, the journey to fully understanding the ecommerce business ecosystem begins with understanding traffic (i.e., the flow of users to the online store) and acquisition (i.e., where these users come from). Traffic and acquisition illustrate the path your customers take to reach you, shedding light on their origins, preferences, and behaviors. Using these principles, we go above and beyond counting visits to the website, rather, we’re decoding the story behind each click and the strategic insights these user journeys offer for growing the business and improving our process and, ultimately, the bottom line.

  1. Website Traffic: Understanding the source of your website (i.e., the online business) traffic is fundamental. It reveals where your audience comes from. Understanding the source from which users come from social media advertisements, organic searches, newsletters, and paid searches will give you an idea of where to allocate promotional resources. In combination, you will want a firm idea of their browsing preferences (e.g., how they navigate your site) and what devices they use (i.e., mobile or desktop). 
  2. Unique Visitors: This metric is key to measuring your store’s reach and potential market growth. It reflects the number of unique individuals visiting your site, offering insights into your ability to attract new customers. This metric is especially valuable to evaluate how it changes over time. In other words, unique visitors tell you how many individual users visit your site versus how many people visit your site multiple times.
  3. Page Views: Page views offer a snapshot of content engagement on your site (i.e., certain pages will be more popular than others). They help you understand which pages appeal to your audience, guiding content strategy and website layout decisions.
  4. Bounce Rate: A crucial metric, the bounce rate indicates how many visitors leave your site without taking an action, such as clicking on a link, filling out a form, scrolling, or making a purchase. It’s essential for assessing user engagement and pinpointing areas for improvement. Bounce rates vary from industry to industry, so it’s important to assess the average bounce rate in your industry prior to making judgments.
  5. Average Session Duration: The duration of time spent by visitors on your site tells you how engaging and relevant it is for your audience. The longer the average session duration is for your users, the more it suggests that your site has compelling content and a more engaging user experience.
  6. Conversion Rate: Conversion rate tells you how many of your users take a desired action (e.g., purchase an item, fill out a form, click a button, sign up for a newsletter, etc.). This is a clear indicator of your website’s effectiveness in turning visitors into customers. Best practices for conversion optimization are vital for increasing this crucial metric.
  7. Cost per Acquisition (CPA): This metric is under the umbrella of return on investment (ROI), as it tells you how much your business spends to acquire customers and/or leads. Understanding and managing your CPA helps you control marketing costs while effectively acquiring new customers.

Sales and Shopping Engagement Metrics

Shopping engagement and sales are the pulse points of your ecommerce business. Broadly, these metrics tell you how relevant your content and sales funnel are and provide actionable insight into areas of improvement. Specifically, these metrics reveal how your customers interact with your products and services and how these interactions translate into tangible sales. These metrics allow you to understand the depth of your customers’ shopping engagement and use that data to increase profitable outcomes.

  1. Average Order Value (AOV): AOV measures the average amount spent per order. Strategies to enhance AOV include upselling, cross-selling, and incentivizing larger purchases (e.g., buy one get one, win a prize, etc.).
  2. Shopping Cart Abandonment Rate: This metric highlights lost sales opportunities during the final step in the sales process. A high shopping cart abandonment rate can indicate a poor user experience, targeting the wrong audience, or a clunky payment platform (among other things). Reducing abandonment involves optimizing the checkout process to ensure a seamless experience and engaging customers with targeted follow-ups.
  3. Order Fulfillment Rate: How many orders are fulfilled immediately following a purchase correlates with customer satisfaction. In an ideal world, you would want this metric to be as high as possible since it helps you track the efficiency of your delivery process.
  4. Product Returns and Exchanges: Managing and minimizing the amount of products that are returned or exchanged is essential for profitability and customer satisfaction. Make every effort to understand the reasons behind this customer behavior. Rates of return may be associated with poor advertising and targeting practices or poor product quality and product descriptions.
  5. Refund Rate: A high refund rate (i.e., the percentage of customers that ask for a refund) can signal issues with product quality, product description, or overall customer satisfaction. Understanding and reducing refunds is crucial for maintaining profitability.

Customer Analysis Metrics

Your customers are the heart of your business. Customer analysis metrics measure behaviors that help you understand your audience more deeply. From their purchasing behaviors to their loyalty, this section explores insights into your customer behaviors so you can forge stronger, more meaningful relationships with your customers.

  1. Retention Rate: This measures the percentage of repeat customers and is a vital indicator of customer loyalty and overall business health. High retention rates often correlate with high customer satisfaction and can lead to increased word-of-mouth referrals (among the most effective promotions).
  2. New vs. Returning Customers: Balancing acquiring new customers while maintaining the retention of existing ones is crucial for sustainable growth. This metric helps businesses understand the effectiveness of their customer loyalty programs and marketing strategies that target new customers, clients, or leads.
  3. Repeat Purchase Rate: Encouraging customers to buy again is key for long-term success. This metric gives your business insight into how many customers make repeated purchases. By nurturing customer relationships through newsletters, special offers, exclusive programs, and other incentives, your business can increase its repeat purchase rate while building a strong community.
  4. Purchase Frequency: Increasing how often customers buy from your store can significantly boost revenue. Strategies to improve this metric include personalized marketing and loyalty programs. 
  5. Customer Acquisition Cost (CAC): Understanding CAC helps to evaluate the effectiveness of your marketing strategies and how your budget should be allocated. Broadly, lower CAC typically signifies more efficient marketing and a healthier return on investment. However, this is industry-specific. Ideally, your business is analyzing CAC over time and regularly.
  6. Net Promoter Score (NPS): NPS gauges customer loyalty and satisfaction, providing actionable insights for improving customer service and product quality. It can serve as a predictive measure of a business’s growth potential and customer advocacy when viewing its change over time.
  7. Customer Lifetime Value (CLV): CLV assesses the total value a customer brings over their total engagement with the business. This is a critical metric when budgeting for an advertising campaign (e.g., a higher CLV can warrant a higher ad spend). Strategies to increase CLV include enhancing customer retention and satisfaction and encouraging repeat purchases.
  8. Customer Satisfaction Score (CSAT): CSAT assesses customer satisfaction with their purchase experience and their experience with the product after the purchase. It offers valuable feedback for improvements. This metric is crucial for identifying areas in the customer journey that need enhancement.

Marketing and Advertising Metrics

Standing out in the content and advertisement ecosystem is difficult but critical to growth. This section focuses on the metrics that gauge the effectiveness of your marketing and advertising efforts. Here we discuss the metrics that will allow you to understand the accurate and actionable impact of your marketing campaigns on brand awareness and conversion.

Consistent marketing analytics (i.e., metrics) review is important when reviewing your ecommerce business’s performance. Without properly configured analytics that are assessed on a regular basis, your ecommerce business will not grow as well as it could.
  1. Click-Through Rate (CTR): CTR measures the effectiveness of your online advertisements that are external to your website. Higher rates indicate more engaging and relevant ads. Higher rates not only indicate more engaging ads but also can significantly improve the quality score of your ad campaigns, potentially reducing cost. It’s important to mention that CTRs vary across industries.
  2. Cost per Click (CPC): Monitoring CPC helps you optimize ad spend and improve the cost-effectiveness of your campaigns. It’s an essential metric for managing ad budgets and ensuring that marketing expenditures lead to significant returns. CPC also varies across industries.
  3. Conversion Rate from Ad to Sale: This metric assesses the effectiveness of advertisements in generating sales, guiding your advertising strategies for maximum ROI. A strong conversion rate indicates that the ads are well-targeted and resonate with the intended audience. It’s important that your analytics model is appropriately configured.
  4. Email Open Rate: The open rate of your email campaigns indicates the effectiveness and relevance of your subject lines and the general interest level of your audience. This metric is critical for optimizing email marketing content and strategies.
  5. Email Click-Through Rate (eCTR): eCTR measures how compelling your email content and your call to actions (CTAs) are in driving recipients to take action, such as visiting your website or making a purchase. It is a key indicator of the relevance and effectiveness of your email marketing messages.
  6. Social Media Engagement: Engagement metrics on social media provide insights into your audience’s interaction with your brand, guiding content, and marketing strategies. They also help identify the most influential and engaging types of content for your audience and give you a sense of your business’s social media community.
  7. Customer Acquisition Cost from Social Media: This measures the cost-effectiveness of social media campaigns in acquiring new leads (on the social media platform) or new customers (on the website), and it is an essential aspect of digital marketing ROI. Efficiently managing this cost can significantly impact the overall profitability of social media marketing efforts.

Inventory and Operations Metrics

Efficient inventory and operations are the backbone of any successful ecommerce business. This section delves into the metrics that keep the wheels of your business turning smoothly. From inventory turnover to order fulfillment, we’re looking at the operational health of your business and how it aligns with customer satisfaction.

  1. Inventory Turnover: This metric helps you understand how quickly inventory is sold and replaced, a key factor in managing stock levels and cash flow. High inventory turnover can indicate strong sales or effective inventory management, whereas low turnover might signal overstocking or market demand issues.
  2. Days Inventory on Hand (DIO): DIO measures how long your inventory sits before being sold, guiding decisions on stock management and ordering from wholesalers. Optimizing DIO is crucial for reducing holding costs and capital tied up in inventory.
  3. Stockout Rate: Minimizing stockouts is crucial for customer satisfaction and sales. This metric (which measures the amount of products unavailable when needed) helps you track and improve inventory availability, ensuring you meet customer demand without overstocking.
  4. Order Processing Time: Efficient order processing enhances customer satisfaction. This metric tracks the speed and efficiency of your order fulfillment process, which is critical in building customer trust and loyalty.
  5. Shipping Cost: Managing shipping costs effectively is crucial for profitability. This metric helps you balance shipping speed with cost, and is key for developing a competitive yet cost-effective shipping strategy.
  6. Returns Processing Time: Quick and efficient handling of returns improves customer satisfaction and operational efficiency. Streamlining this process can significantly reduce overhead costs and improve overall customer experience.

Website and User Experience Metrics

Your website is your digital store, and its user experience can make or break customer relationships. In this section, we discuss the metrics that help you understand how visitors interact with your website. These metrics will give you insight into the usability, design, and functionality that shape the customer journey online.

  1. Page Load Time: Faster page loads improve user experience and can positively impact conversion rates. Indeed, customers expect a fast page load time (under 2 seconds). A swift website is essential in retaining visitors and reducing bounce rates. It is additionally important for SEO.
  2. Mobile-Friendliness: With the majority of online shopping occurring on mobile devices, optimizing your site for mobile users is essential. Ensuring a seamless mobile experience can greatly enhance customer engagement and sales.
  3. Website Search Functionality: Effective search functionality enhances product discoverability and user experience. A robust and intuitive search feature can significantly increase product visibility and user satisfaction.
  4. Product Page Views: Analyzing product page views helps you understand customer interest and guide inventory decisions. This metric is crucial for determining which products are most appealing to your audience and warrant further marketing efforts, and which products may need work on product descriptions and different marketing strategies.
  5. Product Reviews and Ratings: Leveraging customer feedback through reviews and ratings can boost trust and inform product improvements. Encouraging reviews can also provide valuable customer insights and enhance your product offerings.
  6. Add to Cart Rate: This metric indicates customer purchase intent and can guide strategies to improve product appeal and descriptions. A high add to cart rate is a strong indicator of effective product presentation and pricing.
  7. Error Rate: Minimizing website errors is key to ensuring a smooth and satisfying user experience. Reducing errors not only improves customer satisfaction but also bolsters the reliability and credibility of your ecommerce site.

Product and Pricing Metrics

Products and pricing metrics are the pair that will help you optimize your ecommerce business strategy. This part of the article examines the metrics that help you understand how your products perform and how pricing strategies affect your business. Through these metrics, we uncover the stories they tell about consumer preferences and market trends.

  1. Product Conversion Rate: Maximizing sales for individual products requires understanding and optimizing the factors influencing purchase decisions. Analyzing customer feedback and market trends can provide valuable insights for improving product appeal and conversion rates.
  2. Conversion Rate by Product Category: Understanding performance across different product categories helps tailor marketing and inventory strategies. This metric can also guide product development and promotional activities to align with customer preferences in each category.
  3. Price Elasticity of Demand: Responding to price sensitivity in the context of demand is key for your pricing strategy, which, in a reciprocal fashion affects demand and, ultimately, revenue. Regularly monitoring competitors’ pricing and market conditions can help adjust your prices dynamically to stay competitive and profitable.
  4. Profit Margin: Maximizing profit margins involves balancing pricing strategies with cost control for each product. Efficient supply chain management and cost-effective marketing strategies are essential to enhance profit margins without compromising product quality or customer satisfaction.

  3. Gross Profit: Gross profit metrics help assess the financial health of your business, indicating the effectiveness of your sales and pricing strategies. Moreover, tracking gross profit over time can highlight the impact of changes in pricing, cost control, marketing costs, and sales volumes on your business’s overall financial performance (among other things).

  5. Return on Investment (ROI): ROI evaluates the efficiency of your investments in the business, guiding future business decisions and strategy. A high ROI indicates that the investment gains compare favorably to their cost, thereby validating the effectiveness of your investment choices.
  6. CAC to CLV Ratio: Balancing customer acquisition cost with lifetime value is critical to long-term profitability and sustainability. Optimizing this ratio ensures that the cost of acquiring a new customer does not outweigh the revenue they are expected to generate, thereby maintaining a healthy profit margin.


Understanding and utilizing these 50 metrics within the context of your specific business goals, industry, and target audience will offer you a comprehensive way to measure multiple facets of your ecommerce business. Subsequently, these metrics will help you make informed decisions, optimize operations, and drive growth.
