Shopify & Meta Pixel/CAPI Expert Needed — Urgent Tracking Audit and Fix

We need an experienced Shopify and Meta tracking specialist to urgently audit and fix serious conversion and landing-page tracking issues for an ecommerce store. Current issues: * Shopify records orders, but Meta is not reliably tracking or attributing Purchase conversions. * Meta recorded 1,077 outbound clicks but only 249 landing-page views. * One static ad generated 574 outbound clicks but only 12 landing-page views. * Ads currently link to the main homepage, which can redirect visitors to incorrect regional Shopify Markets. * The site uses Iubenda, Shopify customer privacy tools and a separate consent-tracking integration, which may be blocking or undercounting events. * The landing page is heavy and has third-party JavaScript errors, so we need to determine whether visitors are failing to load the page or successfully landing but remaining untracked. Scope of work: * Audit Meta Pixel, Conversions API and Shopify’s Facebook & Instagram integration. * Check for duplicate, outdated or conflicting pixels. * Audit Shopify Customer Events and all app/custom pixels. * Check Iubenda, Shopify Customer Privacy API and UK/EEA consent handling. * Diagnose the outbound-click-to-landing-page-view discrepancy. * Test the website inside Instagram and Facebook’s in-app browsers. * Check homepage, regional redirects, Shopify Markets and destination URLs. * Identify and fix page-loading or tracking-related JavaScript issues. * Verify PageView, ViewContent, AddToCart, InitiateCheckout and Purchase events. * Confirm browser and server events are correctly deduplicated. * Complete an end-to-end controlled test and provide screenshots or a recording proving that all events fire correctly in Shopify Pixel Helper and Meta Test Events. * Provide a short summary explaining the root cause and changes made. We need someone who will implement and verify the fixes, not simply send a generic audit report. Required experience: * Shopify tracking and Customer Events * Meta Pixel and Conversions API * Meta Events Manager and Test Events * Shopify Pixel Helper * Consent-management platforms, ideally Iubenda * Shopify Markets and international URL routing * Mobile and in-app browser troubleshooting Budget: $100 fixed price Timeline: Ideally completed within 24–48 hours If substantial theme development is required beyond configuration and tracking repairs, this must be clearly evidenced and scoped separately before any additional work begins.
