AI Search Glossary
Structured Data
Structured data is machine-readable markup embedded in a web page that describes its content, type, and properties in a standardized format that search engines and AI crawlers can parse without interpreting prose.
In detail
The three main formats are: JSON-LD (recommended — placed in script tags), Microdata (embedded in HTML attributes), and RDFa (embedded in HTML). JSON-LD using the Schema.org vocabulary is the standard recommended by Google and most AI search systems. Structured data reduces ambiguity — instead of an AI guessing your business type from prose, the JSON-LD tells it directly.
