20 eCommerce KPIs for Managers to Track in 2023

eCommerce KPI

Irrespective of the industry, anyone working in an organization or running a business is sure to be familiar with the term KPI or Key Performance Indicators. 

Concerning the eCommerce industry, it is no secret that eCommerce KPIs play a vital role in the survival and growth of your online store. Experts in the industry believe that focusing on the right KPIs can help store owners achieve their long-term and short-term goals.

In order to do so, working on the right KPIs becomes quintessential. Bearing that in mind we have created a list of our top eCommerce KPIs for managers.

We begin with the most critical KPIs for Magento-

1. TTFB


Time to first byte or TTFB plays a vital role in store performance. TTFB determines the time it takes for the user to receive content once they are viewing the web page.TTFB is the same as the server response time therefore it is also determined by the time taken for the browser request to receive the first byte in response.
Previously,  Google suggested that TTFB must ideally be 200 milliseconds (0.2 seconds) or less but as of June 2023, under 800 milliseconds is considered acceptable.

Often TTFB can be tested using several methods such as Google page speed insights, lab options such as Gmetrixs, lighthouse etc., field options like Google search console, Chrome user experience report, and so on.To help achieve faster TTFB and improve website performance, businesses often employ cache warming solutions like cWarmer , which preloads and optimizes website caches to reduce response times and provide a smoother user experience.

2. FBC

FBC or First Byte Complete measures how fast the first piece of information arrives in a user’s web browser when they open a webpage. It’s crucial because it’s the first thing that appears when you visit a webpage. If the FBC score is high, it means the webpage loads fast. A high FBC score can make a Magento store’s pages load faster, which promises a better user experience.

3. Page speed

It is how fast a whole webpage loads, including pictures, styles, etc. It’s crucial because people tend to leave a website if it is slow to load. Research suggests that high page speed improves conversion rates and the overall online presence. 

It is calculated by Google’s Lighthouse tool, which takes into account a number of factors, including the size of the page, the number of resources that need to be loaded, and the time it takes for those resources to be loaded.

Some other important examples of KPIs include:

Sales KPIs

  1. Conversion Rate: It is the percentage of website visitors who take a desired action, such as making a purchase. A high conversion rate indicates that your site is effectively convincing visitors to go ahead and take action, ultimately boosting revenue.

3. Shopping Cart Abandonment Rate: This eCommerce KPI measures the percentage of visitors who add items to their shopping cart but do not complete the purchase. A high abandonment rate may indicate issues with your pricing, checkout process, or user experience, which need to be addressed to improve conversion rates.

CAR = (Total Number of Completed Transactions / Total Number of Shopping Carts) x 100%

4. Customer Lifetime Value (CLV): CLV tells you the total revenue a customer is expected to generate for your business during their association with your brand. It generates loyalty and increases repeat purchases. CLV helps you understand the long-term value of your customers and how to focus on retaining them. Thereby identifying cost per acquisition.

CLV = Average Customer Value * Average Customer Lifespan

Positive feedback can boost your reputation, while negative feedback points to areas to address.
