Merchant Center Reviews for WooCommerce

Merchant Center Reviews for WooCommerce connects WooCommerce with Google Customer Reviews / Google Merchant Center review features.

The plugin adds the Google Customer Reviews opt-in prompt to the WooCommerce order confirmation page, helping eligible stores request post-purchase feedback from customers. It also lets you choose a clear review-display mode: Google’s current floating store widget for bottom-left or bottom-right placement, or the legacy Google Customer Reviews badge for inline shortcode placement or old floating badge behavior.

The checkout opt-in data is only output on a valid WooCommerce order-received URL after the order key has been checked. The optional Google Tag Manager/dataLayer event is privacy-minimized and excludes direct customer contact and address fields.

Key features

• WooCommerce checkout opt-in – automatically displays the Google Customer Reviews opt-in prompt on the order confirmation page.
• Google Merchant Center ID setting – enter your numeric Merchant Center ID in a dedicated WooCommerce admin page.
• Opt-in placement controls – choose supported Google opt-in styles such as center dialog, bottom tray, bottom-left, bottom-right, top-left, or top-right dialog.
• Estimated delivery date – set the number of delivery days used for Google’s review invitation timing.
• Product GTIN support – sends valid GTIN values when available using WooCommerce’s global unique ID field and common GTIN/EAN/UPC metadata fallbacks.
• Clear display mode selector – choose New Google store widget, Legacy Google Customer Reviews badge, or no display.
• New store widget controls – choose bottom-right or bottom-left placement and optional desktop/mobile margins using Google’s current merchantwidget.js integration.
• Legacy badge controls – keep the old Google Customer Reviews badge for [gmc_review_badge] inline placement or old bottom-left/bottom-right floating placement.
• Optional GTM/dataLayer event – pushes a privacy-minimized event to an existing dataLayer or gtag setup when enabled.
• WooCommerce and HPOS-friendly – reads order data through WooCommerce CRUD methods and declares custom order table compatibility.
• Defensive loading – checks WooCommerce availability, validates settings, and avoids exposing order data when the order key is invalid.

Where to configure it

After activation, go to WooCommerce -> Google Merchant Center Reviews to enter your Merchant Center ID and configure checkout opt-in, review display mode, new store widget settings, legacy badge settings, script placement, debug mode, and optional GTM tracking settings.

Google may collect aggregated engagement data for the store widget. The current store widget mode passes widget placement and margin settings to Google; it does not pass customer order data. If the optional GTM/dataLayer event is enabled, the plugin sends a local browser event to the site’s existing analytics/tagging setup. The plugin does not load Google Tag Manager itself. The event payload is limited to event name, order total, currency, order number, item count, shipping country, and product ID/SKU/quantity/line total data; it does not include customer name, email, phone number, street address, postcode, city, or customer ID.
