Syncing your entire product catalog
The Product Sync for GBP plugin has a sync feature that will let you sync or unsync all of your WooCommerce products with one single click.
After connecting your Google account and selecting a location, the Sync section will become visible in the plugin settings.
Pressing Sync products will sync ALL public WooCommerce products to the selected Google Business Profile listing.
Undo sync will delete/unsync ALL products created by the plugin from the selected Google Business Profile listing, not just the ones created by this bulk sync feature.
