Importance of Proper GA4 and Meta Conversion Tracking Setup

If you set up GA4 or Meta (Facebook) conversion tracking without following the platform’s recommended array/object structure, your event data might still fire — but it will be incomplete, misformatted, or even invalid. ✅ What happens next? GA4 may show inaccurate event parameters Meta may flag your pixel events with warnings or errors (like Missing value, Invalid parameter format, etc.) Worst of all: your ad campaigns won’t optimize properly, and ROAS will suffer 🎯 Platforms like Meta and GA4 rely heavily on correctly structured event data (especially for dynamic events like purchases, add-to-cart, or lead submissions). That includes things like items arrays in eCommerce, event_parameters, and properly formatted value and currency. 💡 Pro tip: Always check the developer documentation for the exact schema. For Meta, improper setup might even break CAPI events when sent via GTM or server-side.
