Structured data
Structured data is machine-readable information about a page — its products, prices, reviews, and policies — added in a standard vocabulary (Schema.org) so search engines and AI agents can understand it precisely.
Without it, a machine has to guess what a page means from messy HTML. With it, the price, availability, rating, and return policy are stated explicitly.
On Shopify, structured data is what turns a product page into something an AI agent can confidently recommend.
