GA4 for Ecommerce: The 10 Reports That Actually Matter

GA4 gives every ecommerce store the same problem: too many reports, not enough clarity on which ones actually matter week to week. Most teams either check nothing beyond the homepage overview, or drown in exploration reports built for someone else's business.

Here are the ten that earn a regular look — and what each one is actually for.

1. Ecommerce purchases

The baseline. Revenue, transactions, and average order value over time. This is your health check, not your diagnosis — it tells you that something changed, not why.

2. Traffic acquisition

Where sessions come from, by channel. The report most people check first, and the one most likely to mislead if you're only looking at last-click credit. Use it to spot volume shifts, not to make final budget calls on its own.

3. User acquisition

Similar to traffic acquisition, but grouped by the channel that first brought the user to your site — not the one that closed a later session. This is where you'll often find the channels quietly doing the demand-generation work that last-click reporting hides.

4. Landing page performance

Which pages people land on, and how they convert once they do. If a page pulls solid traffic but converts far below your site average, that's a page-level problem, not a traffic problem — and no amount of extra ad spend fixes it.

5. Ecommerce purchases by item

Product-level revenue and conversion rate. Useful for spotting which products convert well once seen, versus which ones get traffic but not sales — a signal worth checking before you assume a whole category is underperforming.

6. Checkout funnel (via Explore)

GA4 doesn't hand you this one by default — it takes a short funnel exploration to build. It's worth the setup. This is where you'll find the exact step people abandon at: cart, shipping info, payment. Guessing at checkout friction without this report is guessing blind.

7. Session conversion rate by device

Mobile and desktop rarely convert the same. A site that looks fine in aggregate can be quietly losing most of its mobile traffic to a slow or clunky mobile checkout — invisible until you split the data by device.

8. Returning vs. new user revenue

Splits revenue by whether the buyer had visited before. A store overly reliant on new-user revenue has a leaky retention problem, even if top-line numbers look healthy. This report is often the first place that shows up.

9. Key events (conversions) trend

Not just purchases — add-to-cart, begin-checkout, and any other event you've marked as a key event. Watching the trend across the funnel, not just at the final step, shows you where drop-off is worsening before it shows up in revenue.

10. Attribution paths (via Advertising > Attribution)

Shows the sequence of channels a customer touched before buying, not just the last one. This is the closest GA4 gets to answering "what actually gets credit" — a question last-click reporting alone can't answer honestly.

The habit that matters more than the list

Ten reports sounds like a lot until you realize the point isn't to check all ten every day. It's knowing which one to open when something looks off — traffic report when volume shifts, landing page report when conversion drops on a specific channel, checkout funnel when cart numbers look fine but revenue doesn't.

None of this works if the underlying tracking is wrong — mismatched events, untracked conversions, or a funnel that was never set up properly. If you're not confident your GA4 is capturing this correctly in the first place, the GA4 Conversion Funnel Guide covers the measurement fundamentals worth checking before you trust any of these reports.
