How to track cart abandonment accurately

You can't fix cart abandonment without measuring it. This guide sets up the analytics events that tell you exactly which step of your checkout flow leaks the most shoppers — so optimisation effort goes to the highest-impact step.

1. 1

   Define the checkout funnel steps

   Most ecommerce funnels have these steps: view_item > add_to_cart > view_cart > begin_checkout > add_shipping_info > add_payment_info > purchase. Decide which steps your platform actually fires events for.

2. 2

   Enable enhanced ecommerce in GA4

   In GA4, go to Admin > Data Streams > Web > Configure tag settings. Enable 'Measure ecommerce events'. This makes GA4 recognise the standard ecommerce events when they fire.

3. 3

   Verify events are firing

   Open your store in a browser, install the GA4 DebugView extension, and walk through a test checkout. Watch DebugView for each ecommerce event. Note any missing events — these are gaps in instrumentation.

4. 4

   Fill in missing events

   For events not fired automatically by your platform, add them via Google Tag Manager. Each event needs the standard parameters (transaction_id, value, currency, items array).

5. 5

   Build the funnel report

   In GA4, go to Explore > Funnel exploration. Add the funnel steps in order. Set a 30-minute window. Run the report.

6. 6

   Identify the biggest drop

   The funnel shows what percentage of sessions complete each step. The biggest drop between steps is your highest-leverage optimisation target. Common big drops: view_cart > begin_checkout (account creation friction), add_payment_info > purchase (payment errors or trust friction).

7. 7

   Set up an abandoned-cart recovery flow

   Connect Webanto Email Marketing to capture cart-abandonment events from your store. Build a recovery sequence (see the abandoned cart email guide).

8. 8

   Re-measure after 30 days

   Compare the funnel after 30 days of changes. The drop at your target step should improve. If it doesn't, you targeted the wrong friction — re-analyse.
