E-Commerce Metrics to Take into Account in 2026

“How do I know which e-commerce metrics to pay the most attention to?” is a question that marketers repeatedly ask themselves.

In this blog post, we’ll look at some of the essential e-commerce metrics for 2026 and discuss how they can help you succeed in the online marketplace. Stay tuned!

What are e-commerce metrics, and why do they matter?

An e-commerce metric is a set of numbers that indicate how well your online store is doing.

Tracking metrics regularly helps you detect areas for improvement and make data-driven decisions. These metrics can, in turn, give you a complete picture of your store’s performance – from the number of sales, conversion rate, and customer satisfaction to the cart abandonment, return rate, and average value of all purchases.

Simply put, with this knowledge, you’ll have a better idea of where to start strategizing for success and avoid pitfalls like high churn rates and cart abandonment.

For example, you can use insights to calculate the impact of changes in your marketing strategy and identify areas where optimization is most needed. 

And remember, customer data in e-commerce is the only way to determine the performance of your marketing strategy. Without it, you can’t test different hypotheses.

How often should I monitor my e-commerce metrics?

The simple answer is “regularly,” but there’s no definitive one.

• Weekly: if you’re starting out, it’s best to monitor your key metrics every seven days. This allows you to observe fluctuations in metrics like return rate and churn rate over a shorter period of time. However, the downside is that doing it too often will be time-consuming and might produce a data overload
• Monthly: this is the sweet spot for tracking e-commerce metrics. On average, it provides enough time for meaningful changes in website traffic and lets you calculate metrics without losing perspective on your overall progress. With this approach, you can also establish more impactful key performance indicators (KPIs).
• Quarterly: if you feel like you have a handle on things and don’t need to perform tracking as frequently, every three months might be a good option for you. Just be sure to revisit your metrics more often if things go downhill or any ads or marketing campaigns underperform.

However, the time between each check will vary depending on many factors.

For example, if you’ve just made changes to your website or launched a new email marketing campaign, then it’s sensible to track metrics more frequently to see whether or not the changes are making a difference. In contrast, if your online store has been running smoothly for a while, you might only need to check the data every few weeks or months.

By choosing an optimal interval, you can ensure consistency in measurement without overwhelming your team.

The most critical metrics for your e-commerce business in 2026

There are several different factors for marketers to consider when measuring the success of a company’s e-commerce operation. By understanding which metrics matter most to your online business, you can optimize your marketing channels and develop a multichannel sales strategy  You can also focus on boosting customer acquisition cost efforts and enhancing traffic quality to improve conversions and achieve higher total revenue.

Which ones should you be paying attention to in 2026?

Website metrics

1. Bounce rate

The bounce rate is perhaps the most popular and frequently used measurement in e-commerce. This figure quantifies what percentage of visitors left your site without viewing any other pages besides that which was first landed on.

A high bounce rate indicates significant UX issues such as site navigation difficulties or overly long page loading times, which could negatively impact your click-through rate and overall user engagement. However, this can also be a sign of poor targeting, meaning that people can’t find what they’re looking for on your site. Addressing these issues, including optimizing your website search for relevance and speed, can improve your bounce rate by encouraging users to stay engaged and explore other pages.

How to track it?

View the bounce rate in Google Analytics by going to Behavior ➞ Site Content ➞ All Pages.

2. Pages per session

This indicator reveals the average number of pages viewed by visitors during a single session.

The lower the number, the less interested visitors are. If the number is high, it suggests that customers are either well-informed or know precisely what they are looking for.

How to track it?

You can track pages per session in the Acquisition Overview report in Google Analytics.

Want to dig deeper into this metric? You can also view the average number of pages per session by channel, source, medium, and referral. Doing so lets you calculate what traffic sources lead to the most engagement.

3. Site speed

This metric measures how quickly your pages are loading. A fast-loading site is essential for keeping customers engaged and preventing them from abandoning your store.

The optimal loading time for an e-commerce site is no more than 2 seconds. If your page load time is too long, try reducing the size of your images and files, as well as optimizing other elements on your site.

How to track it?

There are many options for checking your site speed. One of them is in Google Analytics by clicking Behavior ➞ Site Speed ➞ Overview.

You could also try tools like PageSpeed Insights or GTmetrix to test your site speed.

4. Device type

In 2026, customer experience is everything—especially on mobile, where flawless and optimized user interaction can turn casual browsers into loyal fans.

The device type metric tells you about the technologies your visitors are using. You can use it to tailor your UX design to be compatible with the most popular devices or check which ones your visitors use most often.

You should maintain consistency in the user experience across all types of devices. Testing mobile, web, and tablet performance will help you better understand how customers shop and what works best for each segment, allowing you to further optimize the user experience for the most popular devices.

How to track it?

You can use Google Analytics and go to Audience ➞ Mobile ➞ Overview to see data on device types.

Business metrics

5. Average order value (AOV)

Do you want to know the average amount of money each customer spends at your online store? You can find that out with this metric.

As one of the essential KPIs in e-commerce, average order value not only reveals if you’re generating enough recurring revenue per customer but also helps you identify your most popular products within your customer base. These valuable insights can guide strategies to maximize sales, such as implementing a customer loyalty program to encourage repeat purchases and increase order sizes.

How to track it?

If you want to check your AOV, go to Google Analytics and click on Conversions ➞ Ecommerce ➞ Overview.

6. Customer retention rate

This metric measures your customers’ return rate. It shows how successfully you retain customers once you have initially converted them.

A high customer retention rate is a good sign of providing valuable content and services that keep loyal customers returning.

On the other hand, a low retention rate signals a higher churn rate, meaning more customers are leaving or disengaging over time. If your retention rate is low, consider implementing conversion rate optimization tactics like adding new products or services to your site regularly and hooking them up with a customer loyalty program or giving discounts for the next order.

What’s a reasonable customer retention rate? This metric varies depending on the industry. For example, e-commerce and SaaS companies tend to have a retention rate of around 35%.

How to track it?

The customer retention rate is a tricky one. You can’t simply check it in Google Analytics, so you have to calculate it manually (with e.g., Google Sheets or Excel help) by using the following formula:

The relevant customer data can be viewed by selecting Audience Overview in Google Analytics and filtering the results by the period you wish to analyze.

7. Shopping cart abandonment rate

A significant measurement in e-commerce is the percentage of shoppers who place an item in their basket but never complete the purchase process, resulting in cart abandonment. This metric sheds light on consumer behavior and reveals potential hurdles in the checkout process.

Marketing automation strategies allow e-commerce stores to recover almost one-third of abandoned shopping carts. Such methods include sending shoppers emails about the items left in their carts with an invitation to complete their purchase and offering incentives, such as discount coupons or free shipping, to encourage completion. Tracking customer acquisition cost alongside cart abandonment helps online store owners determine the ROI of these recovery efforts.

How to track it?

Setting up a goal is the easiest way to track the cart abandonment rate in Google Analytics. You have to go to Admin, click Goals under View and create a New plan (note that it takes up to 24 hours to see current data).

8. Checkout abandonment rate

The checkout abandonment rate goes further along the purchase process than the equivalent for shopping carts. The former is the percentage of people who start the checkout process but never complete it.

As with the shopping cart metric, a high checkout abandonment rate signals some potential issues with the complexity of the process. It would help if you reduced these as much as possible.

How can this metric be improved?

• Try to streamline your checkout process – autofill, guest orders, and countdown stages.
• Use social media retargeting.
• Be transparent about all expenses (e.g., taxes, shipping costs) upfront.

How to track it?

You can track this metric in Google Analytics by creating a new goal and monitoring how people complete the checkout process at each stage.

9. Average shopper dwell time

This metric measures how long customers spend on each page of your site.

A high dwell time could indicate that customers are interested in what they see, but it may also suggest that distractions like ads or navigation menus should be reduced. Use this data to optimize each page for clarity, especially for high-traffic landing pages.

How to track it?

With Google Analytics, you can determine the dwell time by checking the Average Session Duration metric. Go to Behavior ➞ Site Content ➞ All pages.

10. Average ticket resolution time

How long it generally takes your customer service team to resolve support tickets reflects its efficiency, which is crucial in shaping user experience and customer satisfaction.

Many businesses tend to focus on having a quick first response time but forget about the most important thing, which is the final resolution of a client’s concerns. Your customer experience will be negatively affected if you delay answering questions for too long, which will inevitably affect your return rate.

A high ticket resolution time could indicate that you need more staff or that your customer service needs some improvement.

How to track it?

Make sure that resolved tickets mean resolved active issues by closely monitoring your system. The metric can be tracked in Google Analytics, but it must be integrated with your customer service solution, such as Zendesk.

Sales metrics

11. Sales conversion rate

This is one of the essential e-commerce metrics, tracking your store’s success at convincing visitors to buy products.

Sales conversion rate can also measure the effectiveness of different marketing campaigns and the efficiency of your sales funnel in guiding potential customers from initial interest to final purchase.

In subscription-based e-commerce sites, the sales conversion rate can also reveal what percentage of leads successfully move through the sales funnel to become paying customers.

How to track it?

To see your conversions overview go to Conversions ➞ Goals. If you want to analyze further, click on Conversions ➞ E-commerce.

12. Customer Lifetime Value (LTV)

Customer lifetime value is how much a customer is worth to a business over the whole relationship period. With lifetime value, you can see how many users you acquired through email marketing or paid searches.

LTV is a critical metric for e-commerce companies looking to enhance total revenue and improve marketing efficiency. By analyzing customer lifetime value, businesses can make smarter decisions about their customer acquisition cost, retention rate, and how much to invest in various marketing strategies. Focusing on LTV enables companies to build a sustainable revenue base that grows with each retained customer.

Diving deeper, customer lifetime value analysis lets you look at different customer segments and uncover valuable patterns. Segmenting by LTV allows you to identify your most loyal, high-value customers and tailor your marketing to engage them in a meaningful way. You might choose to offer exclusive perks, early access to new or complementary products, or personalized offers to keep them coming back. For low-LTV segments, on the other hand, you can experiment with targeted promotions or cost-effective re-engagement strategies to lift their value over time.

How to track it?

In Google Analytics, LTV is still in testing mode. Go to Audience ➞ Lifetime Value to check how it works.

13. Gross margin

This is simply sales revenue minus the cost of products, materials, and goods sold.

By monitoring average margin values on an ongoing basis, it will be easier for you to decide whether or not to reinvest profits for growth in the New Year. Comparing this to other benchmarks will provide accurate insights into your business growth’s sustainability.

How to track it?

In Google Analytics, select Admin, and find Calculated Metrics under View. Create a new metric to view this info whenever you want.

14. Cost per Acquisition (CPA)

Imagine spending thousands on marketing efforts only to wonder, “Was it worth it?” That’s where cost per acquisition (CPA) comes in. CPA isn’t just a number—it’s a critical measure of how efficiently your investment translates into real, paying customers. By estimating how much you spend to acquire each new customer, CPA reveals the true impact of your advertising strategies, whether online or offline. In other words, it’s the amount of money a company spends on gaining a new customer.

CPA is calculated by dividing the total amount of money spent on advertising and marketing in a given time frame, both online and offline, by the number of new customers acquired during that period.

The average CPA for companies within different industries varies depending on their operating sector. For example, retailers can have an average CPA of $30-$50 per customer, while for non-profit organizations, it might be as high as $500-$1,000.

To optimize CPA, test different ads and target audiences, refining strategies until you reach a sustainable balance between cost and results

How to track it?

Check Acquisition ➞ Google Ads ➞ Campaigns and Acquisition ➞ Campaigns ➞ Cost Analysis to analyze how much money you have to spend on gaining a new buyer.

Marketing metrics

15. Traffic source

This metric measures how much traffic comes from different sources, such as organic searches, paid searches, and social media platforms. Understanding where your website visitors are coming from when they browse your online store is vital for targeted campaigns and advertising efforts to the appropriate marketing channels. By analyzing each traffic source’s conversion rate, you can determine which channels are driving not only visits but also meaningful actions, like purchases.

How to track it?

Check Acquisition ➞ All Traffic ➞ Channels to see where your visitors are coming from.

16. Customer engagement rate

Tracking revenue on ads measures how effectively a business engages its current customers. A higher engagement rate not only reflects active customer interest but also strengthens e-commerce customer loyalty. Engaged customers are more likely to return, recommend the brand to others, and contribute to a long-term revenue growth rate.

How to track it?

Take a closer look at such things as:

• The average click-through rate of email campaigns.
• The conversion rate of social media interactions.
• Number of subscribers to your blog or marketing channel.
• A number of leads generated from online advertising channels.

17. The valid email collection rate

This is the percentage of valid email addresses a company gathers during a single campaign. A higher percentage indicates that the campaign was more successful in collecting email addresses, enhancing the likelihood that this contact information will be useful for future email campaigns.

How to track it?

The best way to track email marketing results is to have an email service provider like MailChimp provide you with a downloadable report.

18. Net Promoter Score (NPS)

This customer loyalty metric, known as the net promoter score (NPS), measures how likely customers are to recommend a company’s products or services to others. A high net promoter score indicates strong customer satisfaction, loyalty, and positive brand perception, all of which contribute to a higher likelihood that customers will make repeat purchases from that retailer.

It categorizes respondents into three groups:

• Promoters: enthusiastic supporters of the brand.
• Passives: satisfied but indifferent.
• Detractors: dissatisfied and unlikely to recommend the company.

Beyond tracking satisfaction, NPS can gauge the overall customer loyalty with a company by providing insights into customer sentiment and long-term brand affinity. Businesses with high NPS scores often see increased customer retention, lower churn rate, and increased organic traffic through word-of-mouth referrals, making NPS a key performance indicator for your business and customer loyalty trends.

How to track it?

Set up a 24/7 customer feedback channel integrated with Google Analytics or conduct customer surveys to determine how likely your customers are to recommend your products.

19. Social media engagement

It’s no secret that social media is a powerful tool for e-commerce businesses. Not only can social media help a business build brand awareness, but it can also help drive traffic to a company’s website.

There are many different ways to measure the success of a social media marketing campaign, but one of the most important metrics is social media engagement. This metric estimates the number of interactions on a brand’s social media posts, which can directly contribute to the effectiveness of social commerce by encouraging purchases directly through social platforms. Combining engaging organic content with well-placed ads can amplify these efforts, reaching a wider audience and driving more conversions, while evaluating customer acquisition cost alongside social media engagement metrics helps determine if these strategies are both sustainable and profitable.

How to track it?

One of the most common ways to calculate social media engagement rate is to look at the number of likes, shares, and comments on your posts.

20. Revenue on advertising spent

This metric measures how much money a business brings in from its advertising efforts.

Calculating this metric can help you determine whether or not your advertising efforts are paying off and if the time and money you’re investing into those efforts will lead to future gains.

High revenue on advertising spent is often a sign that your ads are effectively converting website traffic into online sales, making it a critical factor in e-commerce revenue optimization.

How to track it?
