Shopify Metafields
Custom fields on Shopify products, collections, and pages that store structured data beyond the platform's default fields, the mechanism most product data enrichment runs through.
What it means
Metafields let a merchant attach arbitrary structured data to any Shopify object: a material spec, a compatibility list, a certification, a use-case tag. That data can then be surfaced in structured markup, exposed through the Storefront API, or synced into AI-facing feeds. Metafields are the practical Shopify-native mechanism for building the kind of rich, AI-readable product data that generic product descriptions can't hold.
Why it matters for Shopify
Shopify merchants who structure key product facts as metafields, rather than burying them in description text, make that data reusable across schema markup, feeds, and AI-facing APIs.
