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 are eligible for rich results, which tend to earn more clicks. 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.
