5 KPIs Every eCommerce Owner Should Track Weekly
5 KPIs Every eCommerce Owner Should Track Weekly
Running an eCommerce business without tracking your numbers is like driving blindfolded — you’re moving, but you don’t know where you’re going. To grow profitably, you need clarity, and that starts with tracking the right KPIs.
But not every metric is worth your time every single week.
So, here are 5 key performance indicators (KPIs) every eCommerce owner should keep an eye on weekly — not just during a marketing campaign or sale season.
1. Revenue (and Revenue per Visitor)
Let’s start with the obvious one — how much money you’re making. But instead of only tracking gross revenue, go a step deeper:
-
Track revenue per visitor (RPV) — a metric that combines traffic quality and conversion value.
-
Weekly revenue gives you a pulse check: is your store growing, declining, or stuck?
-
If you run ads, watch how revenue fluctuates with ad spend and changes in traffic.
Why it matters: Revenue tells you what’s working right now — so you can double down or fix fast.
2. Conversion Rate
You can have all the traffic in the world, but if nobody's buying, it doesn’t matter.
Track your site-wide conversion rate, and if possible, break it down by:
-
Device type (desktop vs mobile)
-
Traffic source (organic, paid, email)
-
Product or collection pages
The average eCommerce conversion rate is 2-3%. If you’re below that, there’s room for optimization.
Why it matters: Even small increases in conversion rate can lead to significant revenue boosts without spending more on traffic.
3. Customer Acquisition Cost (CAC)
How much are you spending to acquire one customer?
This KPI is essential if you’re running Facebook Ads, Google Ads, or influencer campaigns.
-
Weekly CAC = Total ad spend / Total new customers
-
Compare this against your average order value (AOV). If CAC is higher than AOV, you’re in dangerous territory — unless your LTV (lifetime value) is strong.
Why it matters: It helps you know whether your paid efforts are profitable — and how much room you have to scale.
4. Cart Abandonment Rate
On average, 70% of online carts are abandoned. That’s a huge chunk of potential revenue left on the table.
Tracking this weekly helps you:
-
Spot checkout bugs or payment issues
-
Test new abandoned cart email sequences
-
Use retargeting ads more effectively
Why it matters: Reducing your cart abandonment rate by even 10% can mean a major revenue lift without adding a single new visitor.
5. Returning Customer Rate
Repeat customers are the foundation of a sustainable eCommerce business. They cost less to acquire, and they tend to spend more.
Track how many of your customers are coming back weekly — especially after running a sale or a new product drop.
You can also monitor:
-
Which products or offers generate repeat purchases
-
The average time between purchases
Why it matters: A healthy returning customer rate means you’re building loyalty — not just making one-time sales.
Bonus: Make It a Weekly Dashboard Habit
It’s easy to let data pile up — and then try to make sense of it once a month (or worse, once a quarter).
Instead, create a simple dashboard and set aside 30 minutes each week to check:
-
Revenue and revenue per visitor
-
Conversion rate
-
Customer acquisition cost
-
Cart abandonment rate
-
Returning customer rate
You can use tools like Google Analytics 4, Shopify analytics, or apps like Triple Whale or Lifetimely to automate it.
Final Thought
Data doesn’t just tell you what happened — it tells you what to do next. And when you track the right KPIs weekly, you’ll catch problems early, double down on what’s working, and steer your business toward consistent growth.
Stay data-smart, and your eCommerce brand won’t just survive — it’ll thrive.
