This project requires a freelance expert to implement a complete multi-platform event tracking and validation system for an e-commerce business, ensuring data accuracy, cross-platform consistency, and operational stability. The final deliverables must meet defined quality standards, be thoroughly documented, and allow internal staff to maintain tracking health independently.

Objective
- Deliver a clean, unified, and deduplicated tracking ecosystem across Meta Pixel + CAPI, GA4 Enhanced Ecommerce, TikTok Pixel/Events API, YouTube Ads Attribution, WhatsApp Business, Shopify, and Email UTMs.
- Achieve 100% accurate event tracking, zero duplicates, consistent attribution across channels, and enable weekly data health checks for long-term platform stability.

Scope of Work
- Set up and precisely configure all required tracking platforms, integrating Meta Pixel + CAPI (deduplicated server/browser implementation), GA4 Enhanced Ecommerce (Shopify native), TikTok Pixel, YouTube Ads attribution to GA4, and consistent, clean product ID mapping.
- Establish and configure a unified WhatsApp Business number with call-to-action (CTA) placements on all key touchpoints, including website, product pages, cart, checkout, footer, Instagram, Facebook, and email. Implement event tracking for whatsapp_click and conversation_start where supported.
- Build and run thorough cross-channel validation for all events and parameters, ensuring zero duplication, consistent cross-domain session handling, and correct attribution and mapping in Meta, GA4, TikTok, Shopify, and YouTube systems.
- Compare tracking outputs across platforms for the last 7 days, identify any significant variances or channel drop-offs (>10–20%), document issues and fixes, and supply a written weekly data health routine process for internal staff.

- Remove all legacy or duplicate pixel scripts from Shopify theme and apps.
- Finalize and validate clean deduplicated Meta Pixel + CAPI implementation.
- Ensure TikTok Pixel tracks the full funnel.

- Deliver written instructions for ongoing weekly tracking health maintenance.
