Ecommerce Analytics: What Numbers Actually Matter

Ecommerce Analytics: What Numbers Actually Matter

Your Shopify dashboard shows 47 different metrics. Google Analytics has hundreds more. Your email platform tracks another dozen.

With all this data, why do most ecommerce owners still feel lost?

Because they're tracking everything and understanding nothing.

Let's fix that.

The Problem with Too Many Metrics

I've seen store owners obsess over:

  • Bounce rate (while ignoring conversion rate)
  • Social media followers (while missing email revenue)
  • Page views (while profit margins shrink)

More data ≠ better decisions.

The stores that grow focus on fewer metrics—but the right ones.

The 5 Metrics That Actually Matter

1. Revenue (and Revenue Growth)

Obvious? Yes. But often tracked wrong.

Don't just track: Total revenue Track instead:

  • Revenue vs. last period (week, month, year)
  • Revenue by channel (organic, paid, email, social)
  • Revenue by product category

Why it matters: Growth rate tells you if you're winning. Channel breakdown tells you where to invest.

Example insight:

  • Revenue: $45,000 this month
  • vs. last month: +12%
  • vs. same month last year: +34%
  • Top channel: Email (38% of revenue)

2. Average Order Value (AOV)

Formula: Total Revenue ÷ Number of Orders

Why it matters: Increasing AOV is often easier than getting more customers.

Benchmark: Varies by industry, but track YOUR trend

Ways to improve:

  • Bundle products
  • Free shipping thresholds
  • Upsells and cross-sells
  • Quantity discounts

Example insight:

  • Current AOV: $67
  • Last month: $62 (+8%)
  • Orders over $100: 23% of total (up from 18%)

3. Conversion Rate

Formula: Orders ÷ Visitors × 100

Why it matters: Small improvements = big revenue gains

Benchmarks:

  • Average ecommerce: 2-3%
  • Good: 3-5%
  • Excellent: 5%+

Example calculation:

  • 10,000 visitors, 2% conversion = 200 orders
  • 10,000 visitors, 3% conversion = 300 orders
  • Same traffic, 50% more revenue

Track by:

  • Device (mobile vs desktop)
  • Traffic source
  • Landing page

4. Customer Acquisition Cost (CAC)

Formula: Marketing Spend ÷ New Customers Acquired

Why it matters: Tells you if your growth is profitable

The rule: CAC should be less than customer lifetime value (ideally 3x less)

Example insight:

  • Ad spend: $5,000
  • New customers: 100
  • CAC: $50
  • Average first order: $67
  • Gross margin: 40%
  • First order profit: $26.80
  • Verdict: Losing money on first purchase (need repeat purchases)

5. Repeat Purchase Rate

Formula: Customers with 2+ Orders ÷ Total Customers × 100

Why it matters: Repeat customers are 5-10x cheaper than new ones

Benchmarks:

  • Below 20%: Needs work
  • 20-30%: Average
  • 30%+: Strong retention

Example insight:

  • Total customers: 1,000
  • Repeat purchasers: 280
  • Repeat rate: 28%
  • Repeat customer AOV: $89 (vs $67 for new)

Metrics You Can Stop Obsessing Over

Bounce Rate

Why people obsess: "People are leaving!" Reality: Bounce rate varies wildly by page type. A high bounce on a blog post is normal. Focus on conversion instead.

Time on Site

Why people obsess: "More time = more engaged!" Reality: Sometimes less time means they found what they needed quickly. Track conversions, not minutes.

Social Media Followers

Why people obsess: Big numbers feel good Reality: 10,000 followers who don't buy < 1,000 who do. Track social revenue, not follower count.

Page Views

Why people obsess: "Our traffic is growing!" Reality: Views don't pay bills. Revenue per visitor matters more.

Common Ecommerce Analytics Mistakes

Mistake 1: Comparing Wrong Periods

Don't compare December to November. Compare December to last December. Seasonality matters.

Mistake 2: Ignoring Segments

"Conversion rate is 2.5%" tells you nothing. "Mobile conversion is 1.8%, desktop is 4.2%" tells you where to focus.

Mistake 3: Vanity Metrics in Reports

Your investor/partner/team doesn't need to see page views. They need to see revenue, growth, and profitability.

Mistake 4: Analysis Paralysis

Spending so much time analyzing that you never act. Set a time limit. Make a decision. Move on.
