Overview

How to know if you need GA4 E-commerce Tracking for Custom Websites

  • Route changes on your SPA are not tracked as page views in GA4.
  • Cart events fire asynchronously and are not being captured.
  • Your GTM setup was built for a standard site and misses most of what happens in the app.
  • Purchase events occasionally go untracked when there are client-side failures.

What GA4 E-commerce Tracking for Custom Websites covers

  • Full GA4 e-commerce event schema from view_item through purchase.
  • Virtual page view tracking for history API navigation.
  • Data layer specification against your actual framework and async patterns.
  • Server-side purchase confirmation to prevent client-side data loss.

GA4 E-commerce Tracking outcomes

  • Tested implementation with QA documentation from a real test purchase.
  • Data layer specification your developers can maintain and extend.

GA4 E-commerce Tracking scope and hours

  • 10-20 hours.
  • Developer support required to implement data layer pushes.
  • Delivery confirmed after architecture review and scope agreement.

What makes our GA4 E-commerce Tracking for Custom Websites different

  • You don't get a generic implementation copied from a Shopify or WooCommerce template.
  • We spec data layer pushes against your actual framework, not assumptions about how it works.
  • You don't pay for learning time. We already know where SPAs break standard GTM setups.

GA4 Event Coverage Conversion Gaps Data Quality
Our approach

How we deliver GA4 E-commerce Tracking for Custom Websites.

A structured process built around your stack, your team, and your data.

01

Architecture review

We review your framework and identify where standard GTM triggers will miss events, based on your routing model and async patterns.

02

Data layer specification

Every e-commerce event is specified against your actual application data structures, with push examples your developers can implement directly.

03

Virtual page views

History API navigation is configured so GA4 records route changes as page views, fixing the most common SPA measurement gap.

04

Event implementation

We implement all GA4 e-commerce events in GTM while your development team completes the corresponding data layer pushes.

05

QA and handover

A test purchase validates every event in the funnel from product view to order confirmation, with results documented and shared.

Frequently Asked Questions

Do I need a developer for this?
Yes. Your team needs to implement the data layer pushes. We specify exactly what to push and when — your developers write the application code.
What frameworks do you support?
React, Vue, Angular, Astro, and any SPA using the history API. If you're unsure, describe your stack and we'll confirm before scoping.
What is server-side purchase confirmation and do I need it?
Server-side confirmation fires a purchase event from your server when an order is placed, as a fallback if the client-side event fails. We include it in scope where your platform supports it.
What does QA documentation include?
Results from a test purchase showing every event from view_item through purchase, with screenshots and any issues noted.
