Executive Summary

Implementation guide for setting up Google Tag Manager (GTM) server-side tagging, Enhanced Conversions, First-Party Cookie restoration, and custom offline conversion imports.

Server-Side Tracking & Enhanced Conversion Setup Runbook

Client-side tracking pixels lose up to 30% of purchase data due to browser privacy restrictions and ad-blockers. This technical guide outlines how Mirashka provisions server-side GTM containers on cloud servers to achieve complete tracking fidelity and power high-ROAS bidding algorithms.

1. Cloud Tagging Container Setup

Deploy a dedicated server container on Google Cloud Platform or Cloudflare Workers mapped to a custom first-party subdomain (e.g., `metrics.brand.com`) to preserve analytics cookies for 365 days.

2. Google Enhanced Conversions Integration

Securely hash customer email addresses and phone numbers using SHA-256 before transmitting data to Google Ads, enabling accurate conversion matching across cross-device shopping journeys.

3. Offline Conversion Imports & Lead Status Sync

Automate daily webhook imports connecting your CRM sales stages (Qualified, Opportunity, Deal Closed) directly back into Google Ads to train smart bidding on actual revenue rather than cheap vanity form fills.
