原文外掛簡介
Paste your Measurement ID. Get trustworthy WooCommerce GA4 ecommerce data.
GIA GA4 is a measurement-quality layer between WooCommerce and Google Analytics 4 (optionally Google Ads). It fires the full recommended ecommerce funnel, enriches every line item, backs up purchases server-side, and respects consent — without Google Tag Manager, without a data team, and without turning WordPress into a profit or attribution platform.
What GIA GA4 is
Complete GA4 ecommerce schema — not just purchase, but the real shopping and checkout funnel
Reliable revenue — browser + Measurement Protocol, with session_id, event_id, and consent-aware server sends
Better item data — categories, brand, GTIN, discounts, list attribution, classic templates and WooCommerce Blocks
GDPR-ready by default — Consent Mode V2, CMP bridges, geo rules, and a built-in banner
Store-owner UX — onboarding wizard, verification tools, and a lightweight dashboard for setup and shop pulse
GA4 stays the system of record. GIA GA4 feeds it well; it does not replace it.
What GIA GA4 is not
GIA GA4 deliberately avoids feature creep. It is not:
A profit, COGS, or margin-by-channel tool
A journey analytics or multi-touch attribution platform
A Meta CAPI, TikTok, or ad-spend ingestion hub
A heavy BI dashboard that duplicates GA4
The built-in dashboard gives operational context — weekly order insights, view-to-purchase, top customers — not a second analytics product inside wp-admin.
Who this is for
WooCommerce merchants who want complete GA4 ecommerce without hiring someone for GTM
Stores with a GA4 ≠ orders gap who need Measurement Protocol backup and deduplication
EU/UK shops that need Consent Mode V2 without wrestling CMP + gtag
Growth-minded stores that optionally want Google Ads purchase conversions on the same stack
Not primarily for: agencies running custom GTM containers, or merchants who want P&L-by-channel inside WordPress.
Why GIA GA4 vs other WooCommerce GA4 plugins
Most alternatives stop at purchase (and maybe add-to-cart). GIA GA4 goes deep on measurement quality:
Full funnel completeness (view_item_list through purchase and refund)
Rich items[] parameters on cart and checkout events
First-class WooCommerce Blocks cart and checkout support
Server-side purchase and refund backup with deduplication
Consent Mode V2 and CMP compatibility out of the box
GA4 ecommerce events
Discovery & product
view_item_list — Shop, category, and tag archives (item_list_id / item_list_name)
view_item — Product pages and variable-product variant changes
select_item — Product clicks from classic shop grids (list context persists through the funnel)
view_search_results — On-site product search terms (Extra GA4 events)
view_promotion — On-sale products and WooCommerce store notices
Cart
add_to_cart — AJAX, form submit, and WooCommerce Blocks cart (full item payloads)
remove_from_cart — Cart page, mini-cart, and Blocks cart
view_cart — Cart page and Blocks cart
Checkout
begin_checkout — Classic and Blocks checkout
add_shipping_info — Shipping method selected
add_payment_info — Payment method selected
purchase — Thank-you page with transaction_id, revenue, tax, shipping, coupons, payment method, new vs returning customer, and event_id for deduplication
payment_failure — Checkout validation and payment errors (always tracked; classic + Blocks)
coupon_applied / coupon_removed — Coupon usage
select_promotion — Coupon codes applied at checkout
Post-purchase & account
refund — When a refund is processed in WooCommerce (browser + server)
login / sign_up — Optional (enable Extra GA4 events)
exception — 404 pages (optional)
WooCommerce Subscriptions (when the extension is active)
subscription_started, subscription_cancelled, subscription_expired
Renewal orders sent as purchase via Measurement Protocol
Optional extras (off by default — Extra GA4 events setting)
cart_time_spent — Seconds on cart/checkout before leaving
Core funnel events can be toggled individually in Settings → Events to reduce volume. Checkout errors, coupons, shipping, and payment events are always tracked.
Rich GA4 item data
Every funnel event can include detailed product line items:
Hierarchical categories (up to 5 levels)
Brand (auto-detects common brand taxonomies)
GTIN / EAN / UPC when stored in product meta
Variant, image URL, stock status
Sale discount amount on discounted products
item_list_id and item_list_name carried from list views through add-to-cart and purchase
Product ID or SKU as item_id (setting)
Product Bundles use minimum bundle price in item data
Works on classic templates and WooCommerce Blocks cart/checkout via the Store API.
Server-side purchase & refund tracking
Browser tags are blocked by ad blockers and strict privacy settings. GIA GA4 mirrors purchase and refund from your server using the GA4 Measurement Protocol.
Saves GA4 client_id and session_id on the order at checkout
Sends event_id on server hits to deduplicate with browser purchase events
Retries failed sends via Action Scheduler
Respects stored analytics consent before server sends
Optional multi-currency normalization for foreign-currency orders (WOOCS / WooPayments rates)
Configurable trigger: order Completed or Processing
Add your GA4 API Secret in settings and use the built-in Verify tracking setup tool.
Consent Mode V2
gtag loads with consent defaulting to denied (configurable)
Built-in consent banner (auto-hides when a CMP is detected)
Geo-aware defaults: EU/EEA/UK → denied, US → granted (optional)
Bridges: CookieYes, Complianz, Cookiebot, and the WP Consent API
Order-level consent stored for server-side tracking decisions
Google Ads (optional)
Fire conversion on purchase with your AW- account ID and conversion label
Enhanced Conversions: hashed billing data sent with purchase (same consent rules as GA4)
Other optional features
Google Tag Manager container ID (disable base gtag when GA4/GTM is loaded elsewhere)
Server-side gtag proxy (extends cookie lifetime, reduces blocker impact)
Cross-domain linker settings (domains + incoming parameters)
Transactional email link UTM tagging
First-touch UTM / gclid / fbclid saved to order meta + Traffic Source admin column

Onboarding wizard on first activation
Admin warnings when Google Analytics for WooCommerce or Site Kit may duplicate tracking

Traffic — GA4 sessions, channels, and landing pages via Site Kit when installed (optional)
Products — Local view-to-purchase report (no Google API required for view counts)
Customers — Top customers by lifetime spend
Settings — Full configuration (also at WooCommerce → Settings → Integrations, redirected to GIA GA4 settings)
Known gaps
Transparent limits aligned with the measurement-quality focus:
select_item list attribution on Block Product Collection grids is not yet supported (classic shop grids are supported)
No add_to_wishlist or deep promotion CMS integration unless store-specific
These are extensions of the same GA4 data-quality goal, not a product pivot.
Privacy
Registers WordPress personal data export and erasure handlers
Checkout error logs and product view counters auto-expire (configurable retention: 30–365 days)
Enhanced conversion data is hashed before transmission; not stored by this plugin
