If you want to make smarter decisions and, moreover, grow consistently in the digital world, understanding e-commerce metrics is fundamental. After all, more than just numbers, they are strategic indicators that show what's working and what needs improvement in your online operation. Therefore, in this article, we will present the main performance metrics and also show you how to interpret them to increase sales, reduce costs, and improve the customer experience.

WHY IS TRACKING METRICS VITAL FOR E-COMMERCE?

You can’t run an e-commerce business in the dark. Just as a pilot relies on control panels to guide an airplane, you need indicators to run your business.

In other words, tracking metrics helps you to:

  • understand the consumer behavior
  • Fix bugs in the sales funnel
  • Invest with more precision in marketing
  • Increase conversion and revenues
  • Reduce CAC (Customer Acquisition Cost)

According to NIQ , Brazilian e-commerce revenue grew 18,7% in the first half of 2024 , and in this scenario, those who stood out were stores with well-structured data intelligence. In other words, constant monitoring of metrics is no longer a differentiator; it's a requirement for survival in the market.

KEY E-COMMERCE METRICS TO TRACK

1- Conversion Rate

The conversion rate is the percentage of visitors who make a purchase. Therefore, it's one of the most important metrics.

Formula: (Number of sales ÷ Number of visitors) x 100

If you get 10 visitors per month and make 300 sales, your conversion rate is 3%.

2- Average Ticket

The average order value shows the average amount spent per purchase on your e-commerce site.

Formula: Revenue ÷ Number of orders

If your store makes R$50.000 with 500 orders, the average ticket is R$100.

Practical tip: offer upsell and cross-sell to increase the value per purchase, as well as promotional kits.

3- CAC – Customer Acquisition Cost

CAC reveals how much you spend on marketing and sales to acquire a new customer.

Formula: (Marketing investment ÷ Number of new customers in the period)

Therefore, controlling CAC is essential to ensure long-term profitability.

Reduce CAC with:

  • SEO and Content Marketing Strategies
  • Efficient retargeting
  • Email marketing with segmentation

4- LTV – Lifetime Value

LTV estimates how much revenue a customer generates throughout their entire relationship with your store.

Simplified formula: Average ticket size x Purchase frequency x Average relationship time

Loyal customers cost less and buy more. So use LTV to predict future revenue and also adjust retention campaigns.

Improve LTV with:

5- Cart Abandonment Rate

This metric indicates how many people add products to their cart but do not complete the purchase . According to Nuvemshop , in Brazil, the average rate is around 82%.

Main causes:

  • Lack of payment options

How to act?

  • Automate cart recovery email sends
  • Test different payment methods
  • Show shipping cost first

6- ROI – Return on Investment

ROI shows whether your campaigns are generating profit.

Formula: [(Revenue – Cost) ÷ Cost] x 100

If you invested R$5.000 and earned R$15.000, the ROI is 200%. In other words, a good ROI indicates that your actions are generating financial results.
