Structured Data

Structured Data is the practice of embedding machine-readable markup — most commonly in JSON-LD, Microdata, or RDFa format — into web pages to explicitly communicate information that might otherwise require complex inference by a crawler. While a human reading a page can easily identify that a block of text describes a product with a price, rating, and availability, a crawler must parse layout and language cues to infer this. Structured data removes that ambiguity by directly declaring: "This is a Product, its price is $49, its rating is 4.5, it is in stock."

Google supports dozens of Schema.org structured data types that unlock rich results in SERPs — including FAQPage, HowTo, Article, Product, Review, Organization, BreadcrumbList, and Event. Beyond rich results, structured data directly aids AI systems by providing unambiguous entity definitions, relationship declarations, and factual attributes that can be retrieved with high confidence. AI systems that encounter structured data can extract information reliably without relying on natural language parsing, which reduces errors and increases the precision of citations.

For AI SEO, the most impactful structured data types are FAQPage (makes Q&A directly retrievable), DefinedTerm and Glossary (signals authoritative definitions), Organization and LocalBusiness (establishes entity profile), HowTo (makes step-by-step instructions extractable), and Article/BlogPosting (provides publication context and authorship). Implementing these types signals to AI retrieval systems that the content is well-organized and trustworthy.

JSON-LD (JavaScript Object Notation for Linked Data), placed in a script tag in the document head, is Google's preferred format and is the easiest to implement and maintain. It does not require modifying HTML markup and can be generated programmatically, making it practical for dynamic pages at scale.

A recipe site adds FAQPage and Recipe schema markup to all recipe pages, enabling Google to display FAQ dropdowns in SERPs and allowing AI search systems to directly extract ingredient lists, cooking times, and answers to common questions as structured passages.
