The 7 E-commerce Metrics Every Online Seller Needs to Track Weekly
Many online sellers, from a new Shopify store to an established Amazon reseller, drown in data and act on none of it. This guide cuts through the noise. We'll show you the seven essential e-commerce metrics that truly predict your store's health and how to easily track them, so you can make smart decisions without needing a data analyst.

Why most business dashboards fail
Your Shopify analytics, Etsy Stats, or Amazon Seller Central dashboards can overwhelm you with numbers. Tracking dozens of metrics just leads to confusion, not clear decisions. The goal isn't to report everything. It's to focus on a few key numbers that warn you about problems early, before they hit your bank account.
Metric 1: Monthly Recurring Revenue or Monthly Revenue
This is your total sales amount. For most online sellers, it's total monthly revenue from all sales channels – Shopify, Etsy, Amazon, or your own website. If you sell subscriptions (like a monthly box), track Monthly Recurring Revenue (MRR). Always look at the total number and how it's changing week-over-week or month-over-month. A flat or dropping revenue line when you expect growth is the first sign of trouble for your online store.
Metric 2: Customer Acquisition Cost
How much are you spending to get one new customer to buy from your store? Add up all your monthly marketing costs – Facebook Ads, Google Shopping ads, influencer payments, email marketing software, Etsy ad spend – then divide by the number of new customers who made a purchase that month. If your CAC is climbing (e.g., from $15 to $30) but customer value isn't, your ad campaigns or outreach efforts are losing money. Track this weekly if you're running paid ads on platforms like Meta or Google.
Metric 3: Customer Lifetime Value
How much money does a customer spend with your online store over their entire time buying from you? For most e-commerce businesses, calculate this by multiplying your average order value (AOV) by how many times an average customer purchases per year, then multiply that by how many years an average customer stays active. For example, if your average order is $50, customers buy 2 times a year, and stay for 3 years, LTV is $300. An LTV that is at least 3 times your CAC (LTV:CAC > 3:1) means your online store is profitable and sustainable.
Metric 4: Churn Rate
This is the percentage of customers who don't make a repeat purchase or who cancel a subscription (if you offer one). For transactional e-commerce, it's harder to track directly but you can look at the percentage of customers who made one purchase but didn't return within 90 or 180 days. A high churn rate means you're losing customers as fast as you get them. It's like pouring water into a leaky bucket. If your subscription store loses 5% of customers monthly, that's 5% churn. Track this monthly.
Metric 5: Cash Runway
This tells you how long your online store can keep operating before you run out of cash, assuming your current spending habits. Take your total cash in the bank and divide it by how much cash you're losing each month (your "burn rate" – covering inventory, shipping, ad spend, software fees). You need at least three months of cash in the bank as a buffer. Review this number monthly. It’s the metric that prevents your e-commerce dream from becoming a sudden financial nightmare.
Metric 6: Lead-to-Customer Conversion Rate
This is the percentage of website visitors (or potential customers on Etsy/Amazon) who actually make a purchase. For a Shopify store, it's your overall "Conversion Rate" – total orders divided by total sessions. For Amazon or Etsy, it’s often called "Units Ordered / Sessions" or "Conversion Rate." A typical good e-commerce conversion rate is 1-3%. If this number drops, it means your product pages, pricing, or checkout process might have issues, or your ad campaigns are bringing low-quality traffic. Understanding why it drops saves you time and money.
Metric 7: Net Promoter Score
This shows how likely your online customers are to recommend your store to others. Send a short, one-question survey (e.g., via email after purchase): "On a scale of 0-10, how likely are you to recommend [Your Store Name] to a friend?" Calculate NPS by subtracting the percentage of "Detractors" (scores 0-6) from "Promoters" (scores 9-10). A low NPS means unhappy customers, predicting future bad reviews, fewer word-of-mouth sales, and higher churn before your revenue takes a hit. Aim to survey quarterly.
How to build your weekly dashboard
Get started with a simple Google Sheet. Set up columns for: Metric Name, Last Week Value, This Week Value, Change, and Notes. Every Monday morning, spend 15 minutes filling it in. Get your data from Shopify analytics, Etsy Stats, Amazon Seller Central reports, Google Analytics, your payment processor (Stripe, PayPal), and your accounting software (QuickBooks, Xero). Regularly checking these few numbers will sharpen your focus and improve how you run your online business.

FREQUENTLY ASKED QUESTIONS
How often should I look at my metrics?
Revenue, CAC, and pipeline: weekly. LTV, churn, and NPS: monthly. Cash runway: monthly, more frequently if under six months. The goal is to spot trends before they become emergencies, not to react to daily noise.
Do I need special software for a business dashboard?
No. A Google Sheet updated weekly is more valuable than a sophisticated BI tool that no one looks at. Start with a spreadsheet and add software (Looker Studio, Databox) only when manual data collection becomes the bottleneck.
What is a good LTV:CAC ratio?
3:1 is the commonly cited healthy threshold for a growing business. Below 1:1 means you are losing money acquiring customers. Above 5:1 may indicate you are underinvesting in growth — you have room to acquire more customers at higher cost.
