What is a SKU?
SKU is short for Stock Keeping Unit. They are unique numbers/letters for your products that help you track your inventory and identify your product traits. SKU is also a recommended product schema property that helps search engines understand your product better and increases the chance they will get displayed as rich results. In fact, if your products are missing a SKU, Google Search Console may issue a missing field ‘sku’ warning. But don’t worry. WooCommerce SEO takes care of that, and it outputs the correct Schema for you automatically!
