What Are Hidden Product Meta Fields in WooCommerce?
WooCommerce hidden product meta fields are custom database entries stored in the wp_postmeta table (or embedded as JSON-LD microdata, HTML data-* attributes, or custom table rows) that define specialized product parameters—such as GTIN/EAN barcodes, manufacturer part numbers (MPN), brand names, wholesale pricing tiers, and custom ACF (Advanced Custom Fields) data—which are not always visible in basic storefront product loops.
Scraping these hidden metadata points is vital for comprehensive inventory synchronization, Google Shopping feed generation, and precise catalog migrations.
