If you track the success of your e-commerce business solely by the number of sales that come in, it's safe to say that you aren't maximizing your revenue potential. Every day, your analytics platform provides you with a wealth of information that you could be using to bring in additional traffic, keep people on your website longer and reduce shopping cart abandonment. To improve your sales numbers, you need a deeper understanding of the online sales process -- and that requires tracking your business's Key Performance Indicators. For insights into building a perfect platform, consider what builds a perfect shopping cart.
Do you really know whether your online business is improving or declining? In this article, we'll describe the 10 most important KPIs for ecommerce that you can use to track the success of your retail business.
List of the Most Important Ecommerce Performance Metrics
1. Average Order Value
Problem: If your e-commerce website converts well but you struggle to maintain profitability, your customers may primarily purchase inexpensive items. Are you really doing everything possible to earn the maximum amount from each paying customer? The average order value is a metric that tracks the amount a typical customer spends when ordering. It's also one of the easiest ecommerce performance metrics to improve.
Solution: Many of the items sold online work best with certain related products and accessories. For example, a person who buys a digital camera could probably have a better experience if he or she also buys a memory card, spare battery and carrying case. Install a website plugin to suggest related products to customers during the checkout process, and you'll most likely see a massive improvement in your website's average order value.
2. Shopping Cart Abandonment
Problem: Shopping cart abandonment takes place when a customer adds items to his or her shopping cart and leaves the website without completing the purchase. A person who begins the checkout process has clearly indicated interest, but something has prevented him or her from buying.
Solution: Install a website plugin that displays a pop-up message when the user moves the mouse pointer to the top of the browser window or attempts to navigate to a different website. Configure the plugin to offer the customer a coupon code for immediate use or ask if the user would like to chat with a sales representative.
3. Customer Attrition
Problem: Mentioned above ecommerce KPI helps to keep count of client loss. Some people buy products from a website once and never return. Sometimes, even regular customers can abandon a company suddenly when they find another seller or product that catches their fancy.
Solution: You should already be collecting the customer's email address every time your website makes a sale. Create a list of the customers who haven't purchased from your website in more than a year, and reach out to them. Offer them a discount for coming back, or highlight some of the new products that you've released since the last time they purchased something.
4. New Customer Acquisition
Problem: Does your business have many repeat customers and few new ones? Regular customers are excellent for the stability of your business, but they do little to help your business grow. To stimulate growth and truly increase your company's bottom line, you need to acquire new customers. This often involves strategic planning, including a potential e-commerce re-platforming roadmap.
Solution: If your in-house advertising program doesn't attract enough new customers to make up for the lapsed ones, you need some brand ambassadors to do the work for you. Launch an affiliate program and give bloggers, YouTubers and website owners a share of the revenue for referring customers to your website.
5. Time On Website and Bounce Rate
Problem: Some people visit your website and leave quickly or only view a single page before leaving.
Solution: If people leave quickly after visiting your website, you need to do a better job of telling them immediately that you have exactly what they're looking for. Improving your website's design can have a profound effect on the amount of time people spend during a visit. Does your website feature attractive product photos? Is your navigation system easy to understand? Do you use clear typography?
6. Conversion Rate
Problem: Some people visit your website and browse, but they end up leaving without buying anything.
Solution: Are you having trouble converting visitors into buyers because you can't price items as low as you'd like? Suppliers often use Minimum Advertised Pricing (MAP) policies to prevent sellers from undercutting one another and dragging down the perceived value of products. You can reduce the actual prices that customers pay in other ways, though, without violating a vendor's MAP policy. Consider offering free shipping or "buy one, get one" deals to stimulate conversions.
8. Cost Per Acquisition
Problem: Your business advertises through every channel possible. You're bringing in consistent traffic through Google AdWords, Facebook and retargeting campaigns -- but you're not profitable.
Solution: If your advertising program brings in customers but isn't profitable, you're spending too much to acquire customers. First, examine the conversion rate of your ad campaigns. Do you attract many clicks -- but few sales? Improve the quality of your landing pages or conduct research to find less expensive keywords on which to bid.
9. Website Traffic
Problem: You check Google Analytics each day to see how many visitors your website has received, but the number never seems to grow.
Solution: Although website traffic isn't the only KPI for an e-commerce website, it is probably the most important. After all, you can't make sales if your website doesn't receive visitors. The best way to attract website traffic is to create great content. If your website doesn't have a blog section, start one. If you don't feel comfortable writing content on your own, hire a freelance writer to help. A website with plenty of text content has a better chance of attracting organic search traffic, and a website with plenty of search traffic makes more sales.
10. Inbound Link Acquisition
Problem: When you check your traffic sources, you always see the same websites. You never see any unfamiliar sources because your website isn't attracting new links.
Solution: The quality and quantity of a website's inbound links greatly influence the amount of traffic it receives through Google's search results -- so it is to your benefit to acquire as many new links as possible. Writing great content can help to encourage inbound linking, but you may need to do some outreach as well. Tell bloggers and website owners about your great content and products!

Monthly Update – September 2025
As we enter September 2025, the e-commerce landscape continues its rapid evolution, with customer experience remaining paramount. A key trend gaining significant traction is the strategic implementation of headless commerce architectures. This approach, decoupling the front-end presentation layer from the back-end commerce functionality, offers unparalleled flexibility, scalability, and speed, allowing businesses to deliver highly personalized and engaging shopping experiences across various touchpoints. Merchants are leveraging headless solutions to integrate emerging technologies like augmented reality (AR) and virtual reality (VR) directly into their product showcases, providing immersive experiences that boost conversion rates. Furthermore, the focus on sustainable and ethical sourcing is no longer a niche, but a mainstream expectation. Consumers are increasingly demanding transparency in supply chains and gravitate towards brands that demonstrate a commitment to environmental and social responsibility. Integrating clear communication about your brand's sustainability efforts throughout your product pages and marketing materials can significantly enhance customer loyalty and brand perception in this competitive market. Keeping pace with these advancements is crucial for maintaining a competitive edge and fostering long-term growth.
