5 Shopify Metrics Every Small Store Owner Should Track (But Probably Doesn't)

Most small Shopify store owners check the same two numbers every morning: revenue and orders. That's it. Maybe sessions if they're feeling ambitious.

The problem? Those numbers tell you what happened — not why or what to do next. Here are five metrics that actually predict whether your store is heading up or quietly dying, and what to do with each one.

1. Dead Stock Rate

How many of your SKUs haven't sold a single unit in the last 30 days? Most store owners have 20–40% of their catalog sitting completely still, tying up cash and storage space. Pull your products, filter by zero orders in the last month, and you'll often find the culprit: bad photos, wrong price point, or a product that was a one-time trend.

What to do: Bundle dead stock with best-sellers, run a flash discount, or simply retire the listing. Clearing dead stock frees capital for products that actually convert.

2. Average Order Value (AOV) by Traffic Source

Your overall AOV is a vanity metric. The useful number is AOV broken out by where the customer came from. Instagram buyers often have a completely different spend profile than Google organic buyers. If your paid social campaigns are pulling in $28 AOV while your email list drives $64 AOV, that's a signal to shift budget — not to optimize the Instagram creative.

What to do:In Shopify Analytics, filter the “Sales by traffic referrer” report. If one source is below your break-even AOV, it needs a different bundle or upsell offer before more ad spend goes in.

3. Repeat Purchase Rate

For stores under $100k/month, a repeat purchase rate below 15% usually means you're running a one-shot acquisition machine, not a real business. Acquiring a new customer costs 5–7× more than retaining an existing one. If you don't know what percentage of your buyers come back, you don't know your real economics.

What to do:Find this in Shopify's “Customers over time” report under “Returning customers.” If it's low, a simple post-purchase email sequence (day 3, day 10, day 30) with a relevant offer is the highest-ROI move available to you.

4. Collection-Level Conversion Rate

Your homepage might convert at 2.4% while your “Sale” collection converts at 0.4%. That gap tells you something: either the products in that collection aren't matching the intent of the people browsing it, or the page itself has friction. Most store owners never look at conversion at the collection level — they optimize the homepage and wonder why revenue doesn't move.

What to do:Use Shopify's Online Store conversion report filtered by landing page. Identify your worst-converting collection and check: Does the hero image match what's being sold? Are prices visible without clicking through? Is there social proof?

5. Inventory Velocity (Days of Stock Remaining)

Running out of your top three products kills momentum in a way that's hard to recover from — especially if you're running ads. Days of stock remaining (current inventory ÷ average daily units sold) is the number that should be on your dashboard, not just a raw inventory count. A count of 200 units means nothing if you're selling 50/day.

What to do: Flag any SKU with fewer than 14 days of stock remaining as a reorder priority. Set a calendar reminder or automate it — most small stores lose 10–20% of potential revenue to avoidable stockouts.

These five metrics won't all move at once, and you don't have to become an analyst to track them. The goal is to check them weekly — not daily — and let the patterns tell you where to focus.

The hard part is that Shopify buries these numbers across six different report pages, and pulling them together manually takes an hour you probably don't have.
