WooCommerce failure path
WooCommerce conversion tracking fixes for GA4, GTM, Meta, and Google Ads
WooCommerce tracking failures usually sit around event timing, dataLayer state, thank-you page logic, duplicate tags, or browser and server deduplication. The fix starts by proving where the event path breaks.

TRIGGERS / WHEN
When this usually appears
- after checkout plugin changes
- after GTM container edits
- after consent banner changes
- after Meta or Google Ads setup changes
- after thank-you page customization
- after caching checkout or account pages incorrectly
ROOT PATHS / WHY
Where the failure often sits
- purchase event not firing
- add_to_cart missing
- initiate_checkout missing
- thank-you page logic unreliable
- duplicate events
- dataLayer missing ecommerce parameters
- Meta Pixel and CAPI deduplication issue
- GTM trigger fires too early or not at all
FIRST PASS
Checks closest to the symptom
GTM container installation and duplicate tags
checkout and thank-you event sequence
dataLayer ecommerce payloads
GA4 DebugView state
Meta Pixel and CAPI deduplication
Google Ads conversion diagnostics
WORDPRESS LAYER MATRIX
Plugin names are checks, not separate doorway pages
Use the affected layer to choose evidence. A plugin is not assumed guilty merely because it is installed.

SPRINT OUTPUT
Fix or implementation-ready path
- trace the event path from product to purchase
- fix safe trigger, tag, dataLayer, or plugin configuration issues
- identify duplicate browser and server event paths
- verify the event in the relevant platform
VERIFICATION
The change needs a second measurement
- GTM Preview
- GA4 DebugView
- Google Tag Assistant
- Meta Test Events
- Google Ads diagnostics
- test order when allowed
USEFUL INPUT
What helps reproduce it
- store URL
- affected conversion actions
- test order permission if available
- GTM, GA4, Meta, or Google Ads access
- what changed recently
SCOPE BOUNDARY
What this path does not promise
- ad strategy
- feed optimization
- CRO redesign
- checkout rebuild
- lifetime tracking maintenance
