E-commerce tracking explained

A plain-English guide to e-commerce tracking in Google Analytics 4 — what it tracks, what you can learn from your store data, and how it gets set up on your site.

If you run an online store, standard website analytics only tells half the story. E-commerce tracking extends GA4 to capture purchase data — so you can see what products people buy, how much revenue your site generates, and where shoppers drop off before completing a purchase.

Quick summary

E-commerce tracking in GA4 records purchases, revenue, product views, add-to-cart actions, and checkout steps. This lets you see which products sell best, where customers abandon their carts, and which traffic sources drive the most revenue — not just the most visits.

Key e-commerce metrics

Revenue

The total value of purchases completed on your site, minus any refunds. This is the number most business owners care about most. GA4 reports both Purchase revenue, which covers what people buy from you, and Total revenue, which also counts advertising revenue.

In GA4, you can see revenue broken down by day, week, or month, and compare periods to see whether you are growing.

Transactions

The number of completed purchases on your site. GA4 populates this from the purchase event.

Average order value (AOV)

The average amount spent per order. GA4 has no metric by that name, so work it out as revenue ÷ transactions. GA4 does report an Average purchase revenue metric, but Google defines it only as the average purchase revenue over the period you have selected, so do not assume it is your per-order figure. Increasing it — for example, by recommending related products — is often easier than finding new customers.

Purchase conversion rate

The share of visits that ended in a completed purchase. Google publishes no benchmark for this, and the sensible comparison is your own previous months rather than a figure from a blog post. In GA4 the nearest metric is Session key event rate; use the All events menu above the report to focus it on the purchase key event.

Add to carts

GA4 counts Add to carts — the number of times visitors added items to their shopping carts — from the add_to_cart event. Plenty of add-to-carts with few purchases points at a problem in the checkout.

Cart abandonment

When visitors add items to a cart but leave without buying, that is cart abandonment. GA4 has no metric with that name. What it has is the Purchase journey report, a funnel running Session start, View product, Add to cart, Begin checkout, Purchase, which shows how many people drop off at each step. Read abandonment off the gap between steps.

Where to find e-commerce data in GA4

With e-commerce tracking enabled, open Reports and look for Monetization (Google spells it the American way on screen). Inside you will find:

Monetization overview — a summary of your revenue
Ecommerce purchases — product and service performance
Purchase journey — the funnel from session start through to purchase
Checkout journey — where people drop off during checkout

Can't see Monetization?

These reports live in the Life cycle collection, which only appears on properties set up a particular way. Newer properties often have a Business objectives collection instead and do not show Monetization by default. An editor or administrator can add the reports back from the report library.

Revenue by source

One of the most valuable views: go to Reports, then Acquisition > Traffic acquisition, and look at the Total revenue column. This shows you which channels (organic search, social, email, paid) are actually driving purchases, not just visits.

How e-commerce tracking gets set up

E-commerce tracking never switches itself on. Google is blunt about it: the e-commerce events "aren't sent automatically", so they have to be added to your website or your Google Tag Manager container. (Shopify is the one platform Google names as sending some of them — add_to_cart, begin_checkout and purchase — for you.)

For WooCommerce (WordPress) and other major platforms, we install an integration that sends purchase data to GA4 using the standard events GA4 expects. For custom-built stores, the implementation requires developer work. Chykalophia handles either one for you.

This is separate from a standard GA4 installation. If you are not sure whether you have e-commerce tracking, check your GA4 Monetization reports. If they show no data, ask us to confirm the setup.

Common questions

Does GA4 e-commerce tracking replace WooCommerce reports?

No — they complement each other. WooCommerce has its own built-in order and revenue reports that are generally more accurate for business operations (because they come directly from your orders database). GA4 e-commerce tracking is most valuable for understanding marketing attribution — which channels drive purchases.

Why might my GA4 revenue differ from my WooCommerce revenue?

Several reasons: visitors who declined cookies are handled differently (depending on your consent setup, GA4 either misses those orders or models part of the gap rather than recording them normally), some sessions lose their source data, and refunds are netted off GA4's revenue figures. Always use your store's own records for financial reporting.

Can I track virtual or downloadable products?

Yes. GA4 e-commerce tracking works for any kind of purchase — physical products, digital downloads, subscriptions, and bookings — as long as the purchase sends the correct data to GA4.
