Top 5 Most Important KPIs to Track for Your eCommerce Website

the top 5 most important tips to track for your ecommer website


1. Conversion Rate

Your store might be getting traffic, but how many of those visitors are becoming customers? That's what your conversion rate measures. It tracks the percentage of website visitors who take a desired action, such as making a purchase or signing up for your email list. A high conversion rate means your website is effective at turning visitors into customers.

Conversion Rate = (Number of Conversions / Total Visitors) * 100

This metric speaks to the effectiveness of your website design, marketing strategies, product appeal, pricing strategy, and user experience.

To improve it, you might need to optimize your website design. Think about enhancing product descriptions, using a display merchandising optimizer, and providing social proof.

While the industry benchmarks for conversion rates typically range between 1% and 3%, improving the conversion rate can be challenging. It involves attracting high-quality traffic and maintaining a user-friendly site design. It also significantly impacts other metrics, such as the average order value (AOV) and customer lifetime value (CLV).

2. Average Order Value

AOV is the average amount spent per order. It’s found by dividing total revenue by the number of orders in a certain time (like a day, week, month, or year).

AOV = Total Revenue / Number of Orders

A high AOV is generally considered to be good because it means customers are spending more each time they buy. This can boost your total revenue. But, a high AOV might also mean you’re getting fewer orders.

So, look at your AOV and other numbers like conversion rate and total orders to better understand your eCommerce performance.

Industry benchmarks vary widely based on product types and businesses. Here are some ways to improve your AOV:

3. Customer Lifetime Value

CLV  is the predicted total revenue a customer brings in during their entire relationship with your store. It’s basically an estimate of how much each customer is worth to your business over their lifetime as a customer.

CLV = Average Purchase Value x Average Purchase Frequency Rate x Average Customer Lifespan

CLV is about more than just immediate sales. It predicts future value and helps you focus on keeping valuable customers. Knowing who your high-value customers are lets you personalize the eCommerce experience and use loyalty programs to keep them engaged.

Sudden, unjustified price increases can upset customers and lower this rate. To avoid this, be clear with your customers about any changes in pricing or products.

CLV benchmarks differ a lot. It depends on the type of business and customer buying habits. CLV is influenced by, and influences, AOV and customer retention rate.

4. Cart Abandonment Rate

The cart abandonment rate is the percentage of online shoppers who add items to their cart but leave before buying. It measures the missed sales when customers leave at checkout. Some businesses see rates up to 70%.

Cart Abandonment Rate = (1 – (Total Number of Completed Purchases / Total Number of Shopping Carts)) * 100

You can reduce cart abandonment by improving the store experience. This includes making checkout easy, improving search so customers can find and buy what they want, and better merchandising.

The cart abandonment rate greatly affects conversion rates and CLV.

5. Website Traffic

Website traffic refers to the total number of visitors who come to your eCommerce website during a specific period. This can be measured in various ways, including:

  • Unique visitors: the number of individual users who visited your site during a period.
  • Total visits: the total number of times your website was accessed during a period, regardless of unique visitors.
  • Page views: the total number of individual pages viewed on your site during a period.
  • Sessions: the total number of browsing sessions on your website during a period, each defined by a period of inactivity.

Website traffic doesn’t always mean sales, but it shows your reach and potential audience. By looking at your traffic with conversion rate and bounce rate, you can see how well your website turns visitors into customers.

Google Analytics uses metrics like total visitors and unique visitors, page views and average session duration, traffic sources and channels, bounce rate, and conversion rate to show your traffic.

It is important to prioritize fast load times for a lowered bounce rate and a positive user experience.

There are no set benchmarks as it varies by industry and business model. Increased traffic can boost conversion rates and revenue, but consistent engagement can be challenging.
