See how this WooCommerce plugin syncs products to Google Merchant Center, its free vs. Pro pricing ($49.99/yr or $179.99 lifetime), features, and setup…
This is a WooCommerce plugin, published under the brand "Jon's WooCommerce Plugins," that connects a WooCommerce store's product catalog to Google Merchant Center using Google's Content API for Shopping (with a Merchant API update planned). The developer built it after finding that the official WooCommerce Google merchant feed plugin's attribute-mapping feature did not work correctly.
The plugin pushes core product data (title, price, images, availability, brand, MPN, GTIN, condition) to Google, maps store attributes and terms (color, size, gender, age group, etc.) to Google's required attributes, and runs scheduled automatic syncs. It also supports WooCommerce bundle, composite, and variable products, including setting custom pricing for bundle/composite items -- something the developer flags as missing from the stock WooCommerce feed plugin.
A free tier covers single-market sync with the core feature set. A paid Pro tier adds multi-market sync (selling in multiple countries from one store), Google product category mapping with taxonomy search, offer ID mapping (to preserve a product's Google review history when migrating from another feed tool), and bulk issue reports that can be exported to CSV. Setup requires an existing WooCommerce/WordPress store, a free Google Merchant Center account, and a Google Cloud project; the plugin's own documentation walks through creating the Google Cloud project step by step.
