5 Key Metrics Every E-commerce Merchant Should Track

June 11, 2025

It takes more than just uploading products and crossing your fingers to run an e-commerce store in today's dynamic digital marketplace. Every successful internet business has a solid data-driven strategy, and metrics are the foundation of that strategy.

Monitoring the appropriate e-commerce metrics can mean the difference between stagnation and long-term growth. These metrics give you insight into your company's current state, customer behaviour, and areas for resource allocation. There are dozens of metrics, but five are particularly important:

  • Conversion Rate (CR)
  • Average Order Value (AOV)
  • Customer Lifetime Value (CLV or LTV)
  • Customer Acquisition Cost (CAC)
  • Shopping Cart Abandonment Rate

Let's examine each of these in greater detail and see why they are important.

1. Conversion Rate (CR)


Definition:

(Number of Purchases ÷ Number of Website Sessions) × 100 is the conversion rate.

You can find out what proportion of website visitors turn into paying customers by looking at your conversion rate. It's the most obvious indication of how well your marketing, product line, and website are coordinating.

Why It Is Important

  • A high conversion rate (CR) indicates that your website is successfully converting visitors into buyers.
  • Poor user experience, sluggish load times, ambiguous calls to action, or unpersuasive product pages are all signs of friction, as indicated by a low CR.
  • It's a crucial metric for determining whether traffic acquisition initiatives are producing outcomes.
  • Industry Benchmarks: Although the typical e-commerce conversion rate (CR) is between 2 and 3%, this can differ depending on the device, traffic source, and industry.

Advice for Increasing CR:

Make checkout and navigation simpler. Include trust signals, such as secure payment badges, return policies, and reviews.

2. Average Order Value (AOV)


Definition:

Total Revenue ÷ Order Count = Average Order Value

An important tool for optimizing revenue without raising traffic or ad spend is AOV, which displays the average amount that customers spend on each transaction.

Why It Is Important: 

  • Has a direct effect on profitability
  • Aids in marketing campaign, promotion, and inventory planning
  • A higher AOV improves cash flow by indicating greater value per customer

Strategies to Raise AOV:

  • Combine goods or make product kits.
  • Provide bulk discounts, such as "Buy 3, get 1 free."
  • Establish thresholds for free shipping, such as "Free shipping on orders above ₹999."

When a value proposition is obvious, customers are frequently willing to pay more. Because of this, AOV optimisation frequently produces a quicker return on investment than pure acquisition campaigns.

3. CLV, or Customer Lifetime Value


Definition:

CLV is equal to Average Purchase Value × Annual Purchase Frequency × Customer Lifespan (in years).

CLV calculates a customer's value over time, not just at the time of their initial purchase.

Why It Is Important:

  • Aids in defending marketing expenses
  • Directs loyalty and retention tactics
  • Finds valuable clients to concentrate on

CLV in Practice:
Assume that your typical client spends ₹800 on each order, makes five purchases annually, and remains loyal to you for three years.
800 × 5 × 3 = ₹12,000 is the CLV.
That is the possible value of that customer, which is an important number to keep in mind when deciding how much money you can spend on getting and keeping them.

Ways to Increase CLV:

  • Make your email marketing unique
  • Start a program to reward loyal customers
  • Improve customer service for loyal customers

4. Customers Acquistion Cost (CAC)

Definition:
The cost of acquiring a new client (CAC) is the total of marketing and sales costs divided by the number of new clients brought in.

CAC tells you how much it usually costs to get a new client. This includes costs for advertising, salaries, equipment, and promotions.

Why It Is Important:

  • Helps figure out the return on investment for marketing
  • Important for understanding cash flow and burn rate
  • For growth to be sustainable, CLV must be greater than CAC (CLV > CAC = profitable growth)

Signs of Danger:

  • A CAC that is going up while the CLV stays the same or goes down
  • Low return on ad spending (ROAS)
  • A lot of people leave the page after seeing an ad

Ways to Lower CAC:

  • Make your ad campaigns more targeted
  • Focus on SEO and content marketing. You can get past visitors back for less money

5. Shopping Cart Abandonment Rate


Definition:  

Shopping Cart Abandonment Rate is the number of carts created minus the number of purchases completed divided by the number of carts created. × 100

This number shows the percentage of people who start the checkout process but then give up. This is a clear sign that something is wrong or that they don't trust the site.

Why It's Important: 

  • If a lot of people leave, you lose money.
  • A lot of the time, these problems are caused by extra costs, account creation requirements, or a bad user experience.
  • Can be fixed with the right push. 

How to Stop People from Leaving Their Carts:

  • Make the checkout process as short as possible, with only one or two steps.
  • Let guests check out. Give them discounts for leaving or send them emails to get their carts back.
  • Show shipping costs up front.
  • Even small changes can make a big difference, as the average rate of cart abandonment in the industry is 60% to 80%.
  • Adding metrics to help you make better choices

These metrics depend on each other and can't work on their own. This is how:

  • Increasing AOV can raise CLV without raising CAC.
  • Reducing Abandonment Directly raises the conversion rate
  • A full understanding of CLV vs. CAC is the best way to ensure long-term profits.

Best Ways to Keep an Eye on:

  • Use tools like Google Analytics, Klaviyo, and Shopify.
  • Every day, look for problems; every week, look for trends; and every month, look for strategies.
  • To stay ahead of the competition, compare yourself to the standards in your field.

Don't just collect data; put it to use. Try it out, change it, and make it better. This is how modern e-commerce brands do well.

FAQs

1. What is a good conversion rate for e-commerce?

2–3% is a healthy range, but this can change depending on the niche. Stores that do well can get more than 5% of their sales from good UX and targeted traffic.

2. What can I do to raise my Average Order Value (AOV)?
Set a minimum order amount for free shipping, offer discounts for buying multiple items, suggest related items, and highlight "frequently bought together" items at the checkout.

3. What should a sustainable CAC aim for?

This is based on your CLV. The best CLV: CAC ratio is 3:1 or higher. This means that for every ₹1 you spend on a customer, you get ₹3 back.

4. What makes people leave their shopping carts?
Unforeseen shipping costs, a complicated checkout process, being asked to make an account, or security worries are all common reasons.

5. How often should I check on these numbers?

Weekly for campaign results, monthly for strategy and forecasting, and daily for strange events (like sudden drops).
