A beginner’s guide to understanding your online store data
New to e-commerce analytics? Learn how to read your Shopify or WooCommerce data and find quick wins in GA4.
Looking at dashboards can feel like staring at a cockpit. The good news: you only need a few instruments to fly. This beginner’s guide to e-commerce analytics shows you how to read your data in GA4 and your store platform, find early wins, and build confidence without drowning in metrics.
Start with questions, not charts 🤔
Analytics works best when it answers specific questions. Begin with three:
Where do visitors come from? Channels and campaigns via UTMs.
What stops them from buying? Funnel drop-offs from view to purchase.
Which products create profit? Margin, AOV, and repeat purchase potential.
Once you frame questions, the right metrics will reveal themselves.
Meet your core tools
Shopify or WooCommerce reports: Revenue, orders, products sold, discounts, refunds.
GA4: Events like view_item, add_to_cart, begin_checkout, purchase; exploration reports for funnels.
Marketing platforms: Spend and clicks from Google Ads, Meta, email, and affiliates.
Keep these tools in sync with consistent UTMs so campaign performance lines up across systems.
Build a simple KPI set
Pick a small, durable KPI group so you are never guessing:
Conversion Rate (CR): Percent of sessions that purchase.
AOV: Average basket size, influenced by pricing and merchandising.
CAC: Spend per new customer — essential for budget decisions.
LTV: Total value per customer over time — critical for scaling channels.
RPV: Revenue per visitor — a quick performance snapshot.
Make your data trustworthy
Implement GA4 correctly: Validate that purchase totals match your store within a small variance.
Check consent and duplicates: Ensure events are compliant and not firing twice.
Lock UTM conventions: Decide names for source, medium, campaign, and share a cheat sheet with your team.
Run these three weekly analyses
Funnel analysis: Use GA4 explorations to spot the biggest drop between add_to_cart, begin_checkout, and purchase. Fix one friction point each week.
Product performance: Rank products by revenue and CR. Promote high-CR items and improve content on low-CR traffic magnets.
Channel profitability: Compare first-order margin to CAC. Pause campaigns with negative unit economics, iterate on near-break-even ones.
Quick wins you can ship now
Shipping threshold: Set free shipping just above your median basket to nudge AOV.
Checkout trust: Add badges, returns info, and wallet pay to remove doubt.
Lifecycle email: Send order-delivered messages with helpful tips and a modest cross-sell.
Level up with segmentation
Not all visitors behave the same. Slice by new vs returning, device, and channel. For returning users, look at time-to-second-order to plan email timing. For paid social, track first-order margin and LTV to judge scale potential beyond ROAS.
The habit that beats complexity
Set a 30-minute weekly review. Check CR, AOV, revenue, CAC, and one rotating deep-dive. Document the top insight and a small action. Over twelve weeks, these changes compound.
