Our store uses:
Shopify
Google Tag Manager (Web container)
GTM Server container hosted via Stape.io

This is NOT a basic pixel installation job. We require a specialist experienced in server-side tracking and Meta deduplication.

Meta Ads reporting more conversions than Shopify
Missing key parameters (e.g. fbc, external_id)

Scope of Work
Audit Web & Server GTM containers
Ensure proper passing of:
fbc & fbp
external_id (Shopify customer ID or order ID)
email and phone (hashed)
Confirm correct event_id deduplication between browser and server events
Validate purchase count and revenue accuracy
Improve Event Match Quality score (target 8.5+ where feasible)
Provide screenshots from Meta Events Manager confirming correct setup
Provide short documentation summarising changes made
Required Experience
Applicants MUST have proven experience with:
Shopify ecommerce tracking
GTM server-side (SGTM)
Stape.io hosting
