Structured Data

Machine-readable metadata about webpage content, used by search engines and AI assistants for richer results.

Structured data is metadata embedded in webpages using standardized vocabularies — most commonly Schema.org with JSON-LD encoding — that describes the meaning of content beyond plain HTML. Search engines (Google, Bing) use it to render rich snippets, knowledge panels, and answer features. AI assistants (ChatGPT, Claude, Perplexity) extract it for citations and direct answers. Modern sites layer multiple schema types per page: Organization, Article, FAQPage, BreadcrumbList, Product, Review, HowTo. Empire325 implements comprehensive structured data across every page type and validates with Google's Rich Results Test.
