What is JSON-LD?
JSON-LD (JSON for Linking Data) is Google's recommended format for structured data, embedded via <script type="application/ld+json">. Compared with Microdata / RDFa, it is decoupled from HTML and the easiest to maintain.
How do you apply it in practice?
Validation tools: Google Rich Results Test, Schema Markup Validator. Common pitfalls: non-ISO8601 dates, missing image dimensions, wrong sameAs domains.
Why does it matter for AI search citations?
Generative search engines tend to extract sentences that are clearly defined, consistent and quotable on their own. Writing concepts like "JSON-LD" as one consistent definition across your site, backed by structured data and verifiable sources, lowers the chance of being misread. This improves readiness only; it does not guarantee citations or ranking gains — measure actual citations to know.
