What is Product Schema Markup?
Product schema markup is structured data (JSON-LD format) added to product pages that helps search engines and AI agents understand product attributes like price, availability, reviews, and specifications.
Required and Recommended Fields
- Required: name, image, offers (price, availability, priceCurrency)
- Recommended: description, brand, gtin, sku, aggregateRating, review
- Enhanced: additionalProperty (specifications), material, weight, color, size
Impact on Visibility
Product schema enables rich snippets in search results (star ratings, price, availability badges). Products with complete schema markup get 20-30% higher click-through rates. AI shopping agents consume schema data directly — products without schema are harder for agents to evaluate and recommend.
Implementation
Add JSON-LD script tags to product pages. Most ecommerce platforms (Shopify, WooCommerce) have built-in schema support but often output incomplete markup. Audit your schema with Google's Rich Results Test and fill gaps for specifications, reviews, and brand information.
