This plugin fixes a huge gap in WooCommerce

We’d been struggling with WooCommerce not tracking GTIN and MPN data for the products in our store. This is especially difficult for variable products. We were able to test a pre-release version of this plugin, and it has worked great. Finally we have SKU, MPN and GTIN in our products, transmitting correctly through to our feeds and then also showing up in the correct fields in the structured data.

By default, WooCommerce provide you the SKU field, but no MPN or GTIN field. If you sell on Google shopping or other marketplaces, you need that data included. This plugin is especially nice if you have MPNs for some products and GTINs for others so therefore your structured data is still assessed by Google as OK because you have brand plus one other identifier. Nice job and thank you!
