Key takeaways

• Focus on three to five metrics that directly connect to your business goals rather than tracking everything, as your priorities will change as your business grows from focusing on traffic and conversion rate when new to emphasising customer lifetime value and profit margins when established.
• Check your ecommerce metrics monthly to get reliable performance trends, since daily monitoring can mislead you with temporary spikes from campaigns or viral content that don't reflect true business health.
• Prioritise conversion rate, average order value, and customer lifetime value as the three essential metrics every ecommerce business needs, regardless of size or industry, to understand sales performance and profitability.
• Maintain a customer lifetime value to customer acquisition cost ratio of 3:1, meaning each customer should generate three dollars in revenue for every dollar you spend acquiring them to ensure sustainable profitability.

What are ecommerce metrics and KPIs?

Ecommerce metrics are measurable data points that track your online store's performance, such as sales conversion rate or average order value. Ecommerce KPIs (key performance indicators) are specific metrics tied to your business goals that help you assess overall success.

Here's how metrics become KPIs in practice:

• track the metric: your conversion rate is currently 20%
• set a KPI: you want to increase it to 25%
• build a plan: test tactics like first-time buyer discounts, improved website usability, or a simpler checkout process

You can find ecommerce metrics in several places:

• your ecommerce platform: most platforms include built-in analytics dashboards with core metrics
• Google Analytics 4: provides a broader range of metrics and deeper insight into customer behaviour

What's the difference between metrics and KPIs?

Every KPI is a metric, but not every metric is a KPI.

• Metrics are lower-level indicators for day-to-day operations
• KPIs use metrics as building blocks to measure progress toward specific business goals over a set period

For example, you might track social media reach, impressions, and engagement as metrics. But your KPI could be the total sales generated through social media over one month, because that directly ties to your business goals.

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

How to measure ecommerce success

Ecommerce success isn't measured by a single metric. Instead, you need to track several metrics together to get a complete picture of your business health.

Start by identifying your business goals, then choose three to five metrics that directly measure progress toward those goals. These become your KPIs.

A simple framework for measuring success:

• set clear goals: define what success looks like, for example, increase revenue by 20% this quarter
• choose relevant metrics: select metrics that directly connect to your goals
• establish benchmarks: know your current numbers so you can measure improvement
• review regularly: check progress monthly and adjust your strategy based on what the data shows

The metrics you prioritise will change as your business grows. A new store might focus on traffic and conversion rate, while an established business might prioritise customer lifetime value and profit margins.

How often should you check ecommerce metrics?

Check your ecommerce metrics monthly to get a reliable picture of overall performance. Daily checks can mislead you with temporary spikes from a viral post or new campaign.

Monthly reviews smooth out these fluctuations and show true trends.

When to check more often:

• after launching a new product
• during or after a marketing campaign
• following a website redesign

14 metrics to track

While you don't need to track all of them simultaneously, consider the following 14 ecommerce metrics when deciding what to track for your business.

1. Conversion rate

Conversion rate measures the percentage of visitors who complete a desired action on your site, whether that's purchasing a product, signing up for your newsletter, or submitting a contact form.

Formula: Total conversions ÷ total visitors × 100 = conversion rate

Example: 2,000 visitors and 40 purchases = 2% conversion rate

According to Shopify, the average ecommerce conversion rate sits between 2.5–3%. Your conversion rate helps you understand how much traffic you need to hit your sales targets. Improving it can have a huge impact. Research shows large ecommerce sites can see a 35.26% increase in conversion rate through better checkout design alone.

2. Average order value (AOV)

Average order value (AOV) measures how much customers spend per transaction on average.

Formula: Total order revenue ÷ number of orders = AOV

Example: $10,000 in revenue from 200 orders = $50 AOV

AOV varies by product and business type. For example, the home and furniture industry has an average order value of $253. Beauty and personal care has one of the lowest AOV at just over $70 per purchase. A low AOV can work well for high-volume stores with lower-priced items. Use AOV alongside other metrics for a complete picture.

Ways to increase your AOV:

• set minimum spend thresholds for free shipping or discounts
• create product bundles with your top sellers
• offer upsells at checkout

3. Customer lifetime value (CLV or CLTV)

Customer lifetime value (CLV or CLTV) predicts the total revenue you can expect from a single customer throughout their relationship with your business.

Formula: Average order value × average number of purchases = CLV

Example: $50 AOV × 15 purchases = $750 CLV

CLV helps you set realistic budgets for customer acquisition and retention. If you're spending $800 to acquire each customer but they only generate $750 over time, you need to improve your acquisition efficiency to become profitable. As a benchmark, most sustainable businesses aim for a lifetime value (LTV) to CAC ratio of 3:1, meaning for every dollar spent on acquisition, a customer should generate three dollars in revenue.

4. Customer acquisition cost (CAC)

Customer acquisition cost (CAC) measures how much you spend on sales and marketing to gain each new customer.

Formula: Total sales and marketing costs ÷ new customers acquired = CAC

Example: $5,000 spent over six months with 50 new customers = $100 CAC. This is higher than the average customer acquisition cost for ecommerce businesses, which is around $70.

Every touchpoint before a purchase, from social media to ads to blog posts, contributes to your CAC. You might set a KPI to maintain CAC at $100 or less for the next quarter.

5. Shopping cart abandonment rate

Shopping cart abandonment rate measures the percentage of shoppers who add items to their cart but leave without completing the purchase.

Formula: (Carts created − completed purchases) ÷ carts created × 100 = abandonment rate

Example: 500 carts created and 350 purchases = 30% abandonment rate

The average cart abandonment rate across industries is around 70%. If your rate is higher, consider:

• simplifying your checkout process, as 18% of US online shoppers have abandoned an order because the process was too long or complicated
• being transparent about shipping costs earlier
• offering guest checkout options

6. Bounce rate

Bounce rate measures the percentage of visitors who leave your site after viewing only one page without taking any further action.

A high bounce rate on product pages (typically anything above the industry average, which ranges between 20–45%) may signal issues with page load speed, unclear product information, or mismatched expectations from your ads. You can track bounce rate through your ecommerce platform dashboard or Google Analytics.

7. Impressions

Impressions count how many times your content appears on a website, search results page, or social media feed. Impressions measure visibility, not engagement. Your ad might display 1,000 times but only receive 10 clicks.

8. Reach

Reach measures the number of unique people who see your content. Unlike impressions, which count every display, reach counts each viewer only once, regardless of how many times they see your content.

Low reach suggests you have an opportunity to expand your content's visibility to new audiences. If reach is low but impressions are high, you have an opportunity to expand your audience by reaching new viewers instead of showing content repeatedly to the same people.

9. Engagement

Engagement measures how actively your audience interacts with your content through clicks, likes, comments, and shares.

What good engagement looks like varies by channel:

• paid ads: high click-through rates on your advertisements
• social media: strong likes, comments, and shares on your posts
• email: opens, clicks, and replies to your campaigns

Check engagement rates in the analytics section of each platform.

10. Click-through rate (CTR)

Click-through rate (CTR) measures the percentage of people who click on your content after seeing it.

Formula: Clicks ÷ impressions × 100 = CTR

Typical benchmarks:

• social media ads: around 1%
• Google Ads: an average ecommerce CTR is 2.69% for Google Search and 0.51% for Display ads

A high CTR means your content is compelling enough to drive action. To improve CTR, lead with clear benefits, use strong calls to action, and keep your messaging concise.

11. Store sessions by traffic source

Store sessions by traffic source shows you where your visitors come from. Sources include organic search, social media, paid ads, email, and direct visits.

This metric helps you identify which channels drive the most traffic so you can focus your marketing budget effectively. If social media sessions could be higher given your audience's activity there, adjusting your content strategy or posting frequency can help.

12. Store sessions by device type and by location

Store sessions by device type reveals whether customers browse on desktop, mobile, or tablet. If most visitors use mobile but your site isn't mobile-optimised, you have an opportunity to increase sales by improving mobile experience, especially since conversion rates are often significantly higher on desktop (1.7x) than on smartphones.

Store sessions by location shows where your customers are geographically. This data helps you:

• time promotions for when your audience is active
• target ads to high-performing regions
• adjust shipping options for key markets

13. Month-end inventory

Month-end inventory tracks your stock levels at the close of each month, helping you balance supply with demand.

What your inventory levels reveal:

• consistently high: you may be overpurchasing, tying up cash in unsold stock
• consistently low: you risk stockouts and missed sales

Track this metric over 12 months to identify seasonal patterns and forecast future stock needs more accurately.

14. Refund and return rate

Refund and return rate measures the percentage of orders that customers send back or request refunds for.

Formula: Returns ÷ total orders × 100 = return rate

Returns are a normal part of ecommerce. But a high rate may signal:

• product quality issues
• inaccurate product descriptions or photos
• misleading advertising

To reduce returns:

• use detailed, accurate product descriptions
• include high-quality photos from multiple angles
• provide size guides and specifications
• encourage customers to ask questions before purchasing

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

The most important metrics depend on your business goals and stage. However, three metrics matter for every ecommerce business: conversion rate, average order value, and customer lifetime value.

Prioritise by your current focus:

• just starting out: focus on conversion rate to ensure you're turning visitors into buyers
• growing your audience: track traffic sources to diversify how customers find you
• improving profitability: monitor CAC and CLV to ensure you're acquiring customers profitably
