Why WooCommerce tracking breaks after a theme migration
A practical StoreKite guide to the tracking gaps that appear when an ecommerce store gets a new theme but no measurement rebuild.
Theme migrations often look finished when the homepage, product pages, and checkout render correctly. Measurement usually tells a different story: old DOM selectors disappear, checkout events change, consent timing shifts, and ad platforms receive weaker conversion signals.
What usually breaks first

No fluff. Lessons from real store builds.
- GA4 purchase events lose item-level data.
- Meta Pixel fires browser-only events without a matching server event.
- Consent banners load after tags and create inconsistent legal states.
- Enhanced conversions stop receiving normalized customer fields.
StoreKite treats tracking as infrastructure, not a theme snippet. During a rebuild I map the full event model, connect browser and server events, and verify the actual payloads before the store goes live.
“Server-side tagging lets you collect data more reliably, with better control over how data is processed and where it is sent.”
How to make the migration safe
Start with a measurement inventory, define canonical ecommerce events, then test the funnel with real checkout states. Server-side GTM and Meta CAPI should be part of the launch plan, not a cleanup task after ROAS drops.
