Structured Data

Structured data is any data formatted according to a defined schema or vocabulary so that machines can parse and interpret it without ambiguity. On the web, structured data typically refers to Schema.org markup implemented as JSON-LD, Microdata, or RDFa. It tells search engines and AI models the exact type and properties of the content on a page.

Why it matters for AEO

Unstructured HTML requires AI models to infer meaning from prose, which introduces errors and omissions. Structured data eliminates guesswork: a Product schema block explicitly states the product name, price, availability, and rating, so an AI asked "what does [brand] sell?" can answer with certainty rather than inference. Google's AI Overviews and Perplexity AI both preferentially cite pages with valid structured data.

How to implement

Audit your site for all content types: products, services, people, events, articles, FAQs, local businesses. Map each type to a Schema.org type. Implement as JSON-LD blocks in each page's <head>. Prioritize: Organization (all pages), FAQPage (any Q&A content), Product (product pages), Article (blog posts), LocalBusiness (if you have a physical location). Validate at search.google.com/test/rich-results.
