Key takeaways

• Track conversion rate, average order value, and customer lifetime value as your three core metrics since these directly measure how well you turn visitors into customers, how much they spend, and their long-term revenue potential.
• Check your ecommerce metrics monthly rather than daily to smooth out temporary spikes and reveal genuine business trends that enable better strategic decisions.
• Calculate customer acquisition cost and compare it to customer lifetime value to ensure you're not spending more to acquire customers than they'll generate in revenue over time.
• Use integrated tools that automatically sync your ecommerce platform with accounting software to track metrics accurately without manual calculations and get real-time insights into your business performance.

What are ecommerce metrics and KPIs?

Ecommerce metrics are measurable data points that track your online store's performance. These include sales conversion rates, average order values, and customer acquisition costs.

Ecommerce KPIs (key performance indicators) are specific metrics that measure progress towards your business goals. They help you assess whether your online store is meeting its targets.

For example, if your sales conversion rate is 20% but you want to convert more visitors into customers, you could set a KPI target of 25%.

To reach this goal, you might:

• Offer discounts: Provide incentives for first-time buyers
• Improve usability: Make your website easier to navigate
• Simplify checkout: Streamline your payment process

You can find ecommerce metrics in two main places:

• Your ecommerce platform: Most platforms include built-in analytics dashboards with key metrics
• Google Analytics 4: Provides broader customer behaviour insights and advanced tracking capabilities

What's the difference between metrics and KPIs?

Metrics track day-to-day operational performance in your online store. KPIs combine multiple metrics to measure strategic business goals over specific time periods.

The key difference: metrics show what's happening now, while KPIs show whether you're achieving your targets.

• Example metrics: Social media reach, impressions, and engagement rates show daily marketing performance
• Example KPI: Total sales generated through social media in one month measures whether your social strategy achieves business goals

In short, every KPI is a metric, but not every metric is a KPI.

Ecommerce metrics to track

Here are the most important metrics to track for your business:

Conversion rate

Conversion rate measures the percentage of website visitors who complete a desired action.

Common conversion actions include:

• Purchasing: Buying a product or service
• Email signup: Joining your newsletter
• Contact: Submitting inquiry forms

The formula for calculating conversion rate (CVR) is:

Total number of conversions / total number of visitors x 100 = conversion rate

So, you might have 2,000 people visit your ecommerce store in one day, and 40 of those people purchase a product. That's a 2% conversion rate.

Your conversion rate shows how much website traffic you need to generate sales. Industry benchmark: Many ecommerce stores achieve conversion rates between 2.5–3%, according to Shopify’s ecommerce conversion rate benchmarks.

Average order value (AOV)

Average Order Value (AOV) measures how much customers spend per transaction in your online store.

You can calculate AOV using the formula:

Total order revenue / number of orders = average order value

Let's say your total order revenue for April is $10,000, and you had 200 orders. Your AOV would be $50.

Use AOV to guide your sales strategy:

• Set minimum spend: Offer free shipping thresholds to increase order values
• Create bundles: Package complementary products together
• Upsell premium options: Suggest higher-value alternatives during checkout

AOV varies by business type and product category. Low-priced retailers with large customer bases may naturally have lower AOVs.

Key insight: Always analyse AOV alongside other metrics for accurate business performance assessment.

Customer lifetime value (CLV or CLTV)

Customer Lifetime Value (CLV) predicts the total revenue you'll earn from a single customer throughout their relationship with your business.

The formula for calculating CLV is fairly simple:

Average order value (AOV) x average number of purchases = customer lifetime value

So, if you use the AOV from the previous example ($50) and multiply it by the average number of purchases per customer (for example, 15 purchases), you get a customer lifetime value of $750.

Why CLV matters: It helps you set realistic marketing budgets and acquisition costs.

Example: If customer acquisition costs $800 but CLV is $750, you are spending $50 more per customer than you earn, so you need to adjust your strategy.

Customer acquisition cost (CAC)

Customer Acquisition Cost (CAC) measures the total amount you spend to acquire each new customer.

CAC includes all marketing touchpoints before purchase, such as social media advertising, Google Ads, and content marketing costs.

You can calculate the true cost of acquiring a new customer with this formula:

Cost of sales and marketing / new customers acquired (in a set period) = customer acquisition cost

So, if you spend $5,000 on sales and marketing over six months and gain 50 new customers, your customer acquisition cost is $100 per customer. You might set an ecommerce KPI of maintaining a CAC of $100 or less for the next six months.

Shopping cart abandonment rate

Customers can make it to your checkout, and still not purchase a product. Your shopping cart abandonment rate shows you the customers who almost complete a purchase with you.

Here's how you can calculate this rate for your store:

Shopping cart abandonment rate = (1 − total number of purchases / total number of shopping carts created) × 100.

Cart abandonment rates vary by industry. If your rate is particularly high, you might consider adjusting your payment process or shipping cost to see if that improves things.

Bounce rate

Bounce rate is a useful metric for ecommerce and websites in general.

Bounce rate refers to the number of visitors who leave (bounce) after visiting your site or a particular page. Perhaps they read your blog post but don't click through to any further pages.

Most ecommerce metrics dashboards include bounce rate in their analytics. You can also add bounce rate to your reports in Google Analytics 4.

Impressions

Impressions represent the number of times your content is displayed on a website, a search engine results page, or on social media.

Impressions tell you how often your content has been displayed, not how often people engage with it; your advert might appear in someone's social media feed, but they may not click it.

Reach

Reach and impressions are similar, but there's an important distinction. A single person could have your content shown to them multiple times, creating multiple impressions. Reach is the number of individual viewers who see the content.

This is a useful ecommerce metric to judge how effectively your content is being distributed. Low reach could suggest there's more you could do to get your products in front of fresh eyes.

Engagement

Engagement tells you how much your audience is interacting with your content through clicks, likes, comments, and shares.

A good engagement rate for paid ads would mean lots of people are clicking on your advert. A good engagement rate for social media would mean lots of people are liking, commenting, and sharing your content.

You'll be able to find your engagement rate for specific social media profiles in the analytics section of each platform.

Click-through rate (CTR)

Click-through rate measures the number of times someone clicks on your webpage, advert or social media content.

A high click-through rate tells you your webpages, ads, and content are doing their job, getting more people onto your site to check out your products. Industry benchmarks vary, but Statista reports an average social media click-through rate of around 1%, and an average search click-through rate for Google Ads of about 1.66%.

Achieving a high click-through rate is about making your content compelling, whether it's webpages, social media, or adverts. Try to reference the benefits of your product or business in the text, and be concise.

You can find your click-through rates on Google ads, through your social media platforms, and on your ecommerce platform.

Store sessions by traffic source

Understanding how customers find your store can help decide where to market your business.

You might see that social media-driven store sessions are slow, despite your target market spending time on social media. In which case, you could invest more in your social strategy and content to attract potential customers.

Store sessions by device type and by location

Your customers' device types and locations can have a huge impact on how they shop with you. If your customers prefer to shop on their mobiles, but your store is not optimised for mobile, you could be missing out on sales.

Location can also impact where and when you should be marketing. If your target market is in the southern hemisphere, but you're posting time-restricted discount codes during UK hours, your key customers could be missing your content.

Keep an eye on the location analytics in your ecommerce platform and on social media, so you know when to show up.

Month-end inventory

Tracking month-end inventory helps you plan stock levels more efficiently. If you still have a lot of inventory at the end of each month, it may mean you are buying more stock than you need. If you are running low before month end, you might need to change your purchasing schedule.

Some businesses experience seasonality too, so tracking month-end inventory over the course of a year can help you predict your annual stock requirements.

Refund and return rate

Refunds and returns are a natural part of ecommerce. Until your product lands on their doorstep, customers will never be 100% certain it's a perfect match.

If you notice a high volume of returns and refund requests, it may signal that customer expectations and your product or marketing are not fully aligned. You can use customer satisfaction metrics to identify where to improve.

Make sure your product listings are as accurate and as detailed as possible. Use high quality photos, include a size guide, and recommend customers get in touch if they're unsure about purchasing.

How often should you check ecommerce metrics?

Your ecommerce store is open 24/7, so you can make sales at any time.

But this also means your ecommerce metrics are changing constantly. People are shopping, exploring your social media, and seeing ads at all hours.

Recommended frequency: Check ecommerce metrics monthly rather than daily.

Why monthly works better:

• Smooths out spikes: Averages daily fluctuations from successful posts or campaigns
• Shows true trends: Reveals genuine business patterns rather than temporary variations
• Enables better decisions: Provides sufficient data for strategic planning

Having said that, it's okay to check your metrics more frequently after a new product launch, marketing campaign, or website refresh. No doubt you'll be curious to see the impact of your efforts.

What's the most important KPI or metric to pay attention to?

Bottom line: Every business needs sales to survive.

Three critical KPIs always matter:

• Conversion rate: How well you turn visitors into customers
• Average order value: How much customers spend per purchase
• Customer lifetime value: Long-term revenue per customer

But the most important ecommerce metrics and KPIs for your business will depend on what type of business you run, and what you're trying to achieve.

If you're just getting started, you might set a conversion rate KPI (say, 3.5%) to make sure you're making plenty of sales to get things off the ground.

If you're trying to reach a new target market, you might set a KPI for diversifying your traffic sources (so you're not just relying on one channel for more customers).
