JSON-LD Structured Data

JSON-LD is the schema.org format AI engines use to identify entities, articles, FAQs, products, and organizations on a page.

Overview

JSON-LD wraps a page's facts in a machine-readable envelope so search and AI engines don't have to guess. Organization schema clarifies who you are; Article schema clarifies what a piece of content is and who wrote it; FAQPage schema exposes Q&A pairs verbatim; Product schema exposes price and availability. Without JSON-LD, AI engines fall back to inference — and inference is where citations get attributed to your competitor.

Components

Key facts

  • JSON-LD is the format Google explicitly recommends over Microdata or RDFa.
  • AI engines extract sameAs links to verify entity identity across the web.
  • Invalid JSON-LD silently fails — always validate with the Rich Results Test.
