## Schema.org in 2026: What's New Schema.org released **version 30.0** on March 19, 2026. The vocabulary now contains **823 types, 1,529 properties, 19 datatypes, 96 enumerations, and 535 enumeration members** ([schema.org releases](https://schema.org/docs/releases.html)). Version 30.0 introduced several highly specialized types for professional credentials, e-commerce, and digital supply chain transparency. Key additions relevant to e-commerce: - **Subscription-based services**: new properties for modeling recurring purchase products - **Energy ratings**: structured data for energy-efficient products (EU energy labels, ENERGY STAR) - **Virtual events**: types for online product launches and live commerce - **Digital supply chain**: new types designed to expose supply chain transparency for AI discovery For merchants, the practical impact is on **older deprecated types**: if your theme was built before 2024, run a validation to ensure you're not using deprecated schemas that may now be ignored by AI crawlers. ## Why it matters for AI Without schema.org, an LLM must extract price, availability, and product characteristics from raw page text. It's slow, imprecise, and error-prone. With schema.org, this information is provided in a standard format any AI understands instantly. The data confirms this preference: **68% of Google AI Overview answers** originate from pages that use structured data markup ([Writesonic, 2026](https://writesonic.com/blog/structured-data-in-ai-search)). Pages with FAQ schema are **twice as likely** to appear in Google AI Overviews compared to unstructured content ([Frase.io, 2026](https://www.frase.io/blog/faq-schema-ai-search-geo-aeo)). When AI can't easily parse your data, it may skip your page entirely or provide a low-quality summary - and recommend a competitor instead. ## Essential Fields for AI For AI to understand your product, your schema.org needs to include the right fields with quality values. Beyond field presence, **value quality** matters: a zero price, empty description, or generic name are negative signals. Verity Score automatically analyzes your schema.org completeness and quality, and tells you exactly what's missing or problematic. ## Required Fields Checklist | Field | Required | Validation | |-------|:--------:|------------| | `name` | Yes | > 3 words | | `description` | Yes | > 50 characters | | `image` | Yes | Valid URL | | `brand` | Recommended | Not empty | | `sku` | Recommended | Not empty | | `offers.price` | Yes | > 0 | | `offers.priceCurrency` | Yes | Valid ISO code | | `offers.availability` | Yes | Full schema.org URL | | `aggregateRating` | Recommended | ratingValue 1-5, reviewCount > 0 | ## Common Mistakes 1. **Empty values** : `"brand": { "name": "" }` is worse than missing 2. **Zero price** : `"price": "0.00"` signals free product 3. **Inconsistent duplication** : Two Product blocks with different prices 4. **Wrong availability format** : `"InStock"` instead of `"https://schema.org/InStock"` ## How to Fix on Shopify Edit `sections/main-product.liquid` in your theme and ensure the [JSON-LD](/en/glossary#json-ld) block includes all required fields using Liquid variables (`product.title`, `product.vendor`, `product.selected_or_first_available_variant.price`, etc.). ## Resources - [Schema.org Product documentation](https://schema.org/Product) - [Google Product structured data](https://developers.google.com/search/docs/appearance/structured-data/product) --- ## Related articles - See also: [The Schema.org Guide for Shopify: What AI Actually Reads](/en/blog/shopify-schema-org-guide) - [AggregateRating: Making Your Reviews AI-Readable](/en/kb/aggregate-rating) - [Shipping & Returns: Critical Trust Signals](/en/kb/shipping-returns) - [Claims & Proof: Credibility in the Eyes of AI](/en/kb/claims-proof) - [GEO Audit: The Complete Guide to Optimizing Your Shopify Store for AI](/en/kb/geo-audit) - [Sell on ChatGPT: The Complete Shopify Guide for 2026](/en/kb/sell-on-chatgpt-shopify) --- **Ready to check your store?** [Run a free GEO audit →](https://verityscore.io) ## FAQ ### What is schema.org Product markup and why does it matter for SEO? Schema.org Product is a structured data format that helps search engines and AI models understand product information (price, availability, reviews). It's essential for appearing in Google rich results and AI-powered recommendations. ### How do I check if my Shopify store has Product schema? Open a product page, right-click → View page source, and search for 'application/ld+json'. You can also use Google's Rich Results Test or run a Verity Score audit. ### Which schema.org fields are required for a Shopify product? Essential fields are name, description, image, offers.price, offers.priceCurrency, and offers.availability. Recommended fields include brand, sku, and aggregateRating. ### Does Shopify add schema.org Product markup automatically? Most Shopify themes include basic Product schema, but it's often incomplete (missing brand, SKU, or aggregateRating). You should audit your theme's JSON-LD block in main-product.liquid to ensure all fields are present. ### What happens if my schema.org has wrong or empty values? Empty values (like a blank brand name) or incorrect values (like a zero price) are worse than missing fields. Search engines and AI may interpret them as errors and lose trust in your data. ## Sources - [Why Structured Data in AI Search Matters More Than Ever in 2026](https://writesonic.com/blog/structured-data-in-ai-search) (industry) - [Google AI Overviews Ranking Factors: 2026 Guide](https://wellows.com/blog/google-ai-overviews-ranking-factors/) (industry) - [Schema Markup for AI Search: Ecommerce Guide 2026](https://alhena.ai/blog/schema-markup-ai-search-ecommerce/) (industry) - [Schema and AI Overviews: Does structured data improve visibility?](https://searchengineland.com/schema-ai-overviews-structured-data-visibility-462353) (industry) - [FAQ Schema for AI Search (GEO/AEO)](https://www.frase.io/blog/faq-schema-ai-search-geo-aeo) (industry)
