Analytics implementation demos
Each site below is a working ecommerce journey with its own GA4 property, its own GTM container and its own Consent Mode v2 implementation. They share an origin but never share a page — the containers load per route, so neither property can see the other's traffic.
UK online grocery — multi-item trolley, delivery slots, login gate
Travel eSIM storefront — single-item cart, instant fulfilment
The correct page-view strategy depends on the navigation model, and one site can only demonstrate one answer. Roamio is a single-page app: the document never reloads, so route changes must be pushed to the dataLayer by hand. Freshcart is a multi-page app: every navigation is a real document load, so the Google tag's built-in page view is the only correct source and a manual push would double-count every page.
