10 Essential Metrics You Need to Track When Starting an E-Commerce Business (E-com 101)
Starting an e-commerce business can be both exciting and challenging. Success doesn’t just come from a great product or a well-designed website—understanding and monitoring key metrics is crucial to growth and sustainability. Knowing which numbers to focus on can help you make data-driven decisions, optimize performance, and ensure your business is on the right track.
In this blog, we’ll cover the 10 most important metrics you need to know to start your e-commerce business and achieve long-term success.
1. Conversion Rate
Your conversion rate is one of the most critical metrics in e-commerce. It shows the percentage of visitors to your website who complete a desired action, usually making a purchase.
How to calculate: (Number of sales / Number of visitors) x 100
Why it matters: A higher conversion rate means more of your visitors are becoming customers, which directly impacts revenue. Improving your conversion rate can often be more cost-effective than driving more traffic.
Pro Tip: Optimize your product pages, simplify the checkout process, and test different calls to action (CTAs) to boost your conversion rate.
2. Customer Acquisition Cost (CAC)
Customer Acquisition Cost (CAC) is the cost of acquiring a new customer. This includes the total cost of your marketing efforts, such as ads, promotions, and any other expenses related to acquiring new customers.
How to calculate: Total marketing costs / Number of new customers acquired
Why it matters: Knowing your CAC helps you understand whether your marketing efforts are efficient and sustainable. If your CAC is too high, it can erode your profits.
Pro Tip: Lower your CAC by improving organic traffic, focusing on repeat customers, and optimizing your paid ad campaigns.
3. Average Order Value (AOV)
Average Order Value (AOV) measures the average amount customers spend per transaction on your website.
How to calculate: Total revenue / Number of orders
Why it matters: Increasing your AOV allows you to generate more revenue from your existing customers, improving your bottom line without needing to acquire new ones.
Pro Tip: Implement strategies like upselling, bundling products, or offering free shipping on orders over a certain amount to increase your AOV.
4. Customer Lifetime Value (CLV)
Customer Lifetime Value (CLV) is the total amount of money a customer is expected to spend on your business over the course of their relationship with your brand.
How to calculate: Average purchase value x Average number of purchases x Average customer lifespan
Why it matters: CLV helps you understand how much a customer is worth to your business in the long term. A higher CLV means more revenue from existing customers, making it easier to justify marketing expenses.
Pro Tip: Focus on retaining customers through loyalty programs, personalized marketing, and excellent customer service to boost CLV.
5. Cart Abandonment Rate
Cart abandonment rate tracks the percentage of users who add items to their shopping cart but leave without completing the purchase.
How to calculate: (Number of abandoned carts / Number of initiated checkouts) x 100
Why it matters: A high cart abandonment rate can signal issues with your checkout process or customer hesitation, resulting in lost revenue.
Pro Tip: Simplify the checkout process, offer multiple payment options, and consider using cart abandonment emails to recover lost sales.
6. Website Traffic
Website traffic measures the total number of visitors to your e-commerce site within a given period. It's often broken down into different types, such as organic, paid, direct, and referral traffic.
Why it matters: Website traffic is the foundation for generating sales. However, it’s important to focus not just on the quantity of traffic but the quality—visitors who are likely to convert.
Pro Tip: Improve your SEO to drive more organic traffic, use targeted advertising to attract relevant visitors, and leverage social media to increase brand awareness.
7. Bounce Rate
Bounce rate refers to the percentage of visitors who leave your site after viewing only one page. It can indicate that visitors aren’t finding what they’re looking for or that your site isn’t engaging enough.
How to calculate: (Number of single-page visits / Total number of visits) x 100
Why it matters: A high bounce rate can indicate issues with your user experience, site design, or content relevancy. Reducing your bounce rate can lead to higher engagement and more conversions.
Pro Tip: Improve page load times, offer engaging and relevant content, and make navigation easy for users.
8. Return on Ad Spend (ROAS)
Return on Ad Spend (ROAS) measures the effectiveness of your advertising efforts by showing how much revenue is generated for each dollar spent on ads.
How to calculate: Revenue generated from ads / Cost of ads
Why it matters: ROAS helps you assess whether your ad campaigns are profitable. A high ROAS means your ads are performing well, while a low ROAS suggests you may need to optimize or adjust your approach.
Pro Tip: Regularly test and optimize your ad creatives, targeting, and bidding strategies to maximize ROAS.
9. Refund and Return Rate
Refund and return rate measures the percentage of products returned or refunded by customers. High return rates can indicate issues with product quality, sizing, or mismatched customer expectations.
How to calculate: (Number of returns or refunds / Total orders) x 100
Why it matters: High return rates not only hurt your profitability but also signal customer dissatisfaction. Reducing your return rate can lead to happier customers and better margins.
Pro Tip: Offer detailed product descriptions, high-quality images, and accurate sizing charts to minimize returns. Implement a clear and customer-friendly return policy.
10. Inventory Turnover Rate
The inventory turnover rate measures how often you sell and replace your inventory over a given period. It’s a key indicator of product demand and supply chain efficiency.
How to calculate: Cost of goods sold (COGS) / Average inventory value
Why it matters: A high inventory turnover rate suggests that your products are selling quickly, which is ideal for cash flow. Low turnover, on the other hand, indicates that you may be overstocking or need to adjust your product offerings.
Pro Tip: Use data analytics to forecast demand accurately and manage your inventory levels efficiently to avoid overstocking or stockouts.
