GIA — GA4 Ecommerce Tracking for WooCommerce

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
• Exclude store administrators from tracking
• GA4 DebugView mode
• Gross vs net revenue on purchase events
• Accepts G- and GT- Measurement IDs
• HPOS (High-Performance Order Storage) compatible
• Onboarding wizard on first activation
• Admin warnings when Google Analytics for WooCommerce or Site Kit may duplicate tracking

Built-in dashboard (operational, not BI)

Admin menu: GIA GA4 → Analytics

• Overview — Setup wizard, tracking verification, and weekly WooCommerce insights (revenue, refunds, customer mix, geo, checkout risk, tracking gap vs GA4 when Site Kit is connected)
• 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
