Embedded in HTML with Schema.org vocabulary, it describes organization, offers, FAQ and glossary terms for search engines and AI systems. ## Quick Answer (EN) JSON-LD is a W3C-standardized JSON syntax for linked data. Placed in a script tag, it labels what a page is about using Schema.org types — without changing the visible layout — so machines can read entities and relations reliably. ## Key Takeaways (EN) - JSON-LD lives in a script tag of type application/ld+json and is separate from visible markup. - A single @graph with stable @id values beats many disconnected blocks. - Markup must match visible content; fake schema damages trust. ## English Summary JSON-LD stands for JSON for Linking Data and is a W3C Recommendation. Pages embed it in a script element with the type application/ld+json. With the Schema.org vocabulary it states which entities a page describes — Organization, Service, Article, DefinedTerm — and how they relate through @id references. Google recommends JSON-LD over Microdata and RDFa. Modern Stack emits one consistent @graph per page, generated from the same content that renders in HTML. ## Quick Answer **JSON-LD:** JSON-LD ist eine standardisierte JSON-Schreibweise, mit der du einer Seite maschinenlesbare Bedeutung mitgibst. Du legst sie in ein Script-Element im HTML und beschreibst dort mit dem [Schema.org](/glossar/schema-org)-Vokabular, wer dein Betrieb ist, was du anbietest und welche Fragen die Seite beantwortet. Das sichtbare Layout bleibt unberührt, Maschinen bekommen eindeutige Fakten. > Zitierfähigkeit entsteht, wenn Definition, Struktur und klare nächste Schritte zusammenkommen. > Steve Baka ## Key Takeaways - JSON-LD steckt in `
