Direct-to-consumer eCommerce brand selling premium regional tea blends.

Tea of Sylhet relied heavily on paid acquisition but lacked reliable measurement. Key funnel events were tracked inconsistently and revenue values were not reliably sent to Google Ads. That made it hard to know which campaigns actually drove sales.

The project rebuilt tracking from the ground up: a hybrid browser + server setup with Google Analytics 4, Google Tag Manager and a server container (Stape) using a custom tracking domain so events are delivered reliably even when browsers block cookies or scripts.

Build a resilient end-to-end tracking system that captures the full customer journey, attaches revenue to purchases, and forwards verified conversion events to Google Ads — enabling remarketing and revenue-driven bidding.

• Purchase events lacked revenue values and product details in Ads reporting.
• Google Analytics 4 didn’t follow enhanced eCommerce mapping across the funnel.
• Browser-only tracking suffered signal loss from cookie expiry, ITP and ad-blockers.
• Remarketing lists were generic, not behavior-driven, so conversion potential was low.
• Decision-making relied on fragmented data rather than verified revenue signals.

We adopted a hybrid approach: keep client-side events for immediate UI signals and DebugView visibility, and add server-side processing to validate and forward purchases as authoritative events. A custom tracking domain was used to reduce blocking and treat events as first-party where possible.

• Enabled Google Analytics 4 enhanced eCommerce schema (View Item → Add to Cart → View Cart → Begin Checkout → Purchase).
• Deployed Google Tag Manager Web container for client triggers (clicks, scrolls, engagement).
• Set up Google Tag Manager Server container via Stape and verified a custom tracking domain.
• Mapped Google Ads events with revenue parameters.
• Created behavioral remarketing audiences.
• Validated via Tag Assistant, DebugView & server logs.

• Google Tag Manager (Web + Server)
• Google Analytics 4 (Enhanced eCommerce)
• Google Ads Conversion (server-side)
• Stape.io server container
• Tag Assistant & DebugView

The hybrid tracking setup with a server container and custom domain fixed the core problems: data loss, missing revenue, and weak audiences. Tea of Sylhet can now see which campaigns truly drive sales, create precise remarketing lists, and scale Google Ads with confidence because the numbers are verified.
