Average Client Rating

Businesses that migrated from Universal Analytics to GA4 often carry over a data layer designed for UA's event-category-action model — which doesn't align with GA4's event + parameters model. We migrate your existing data layer to the GA4 ecommerce schema while maintaining backward compatibility where needed, updating GTM tag configurations, and ensuring all platform tags (Meta, Google Ads, TikTok) continue to work through the migration without data loss.
