JSON-LD
JSON-LD is a JSON-based format for embedding structured data — organization, product, article, FAQ — in web pages for search and answer engines.
In plain English
JSON-LD lets you tell search engines what a page is about in a machine-readable way. You embed a <script type="application/ld+json"> block with a JSON object that declares the page's type (@type: Article, Product, FAQPage, DefinedTerm) and its properties. Google uses it for rich results, Microsoft for Bing results, and increasingly Claude and ChatGPT for grounding their answers.
Compared with older structured-data formats (microdata, RDFa), JSON-LD is cleaner: it lives in one place, does not clutter your markup, and is easy to generate server-side. Google's documentation recommends it as the default, and most Schema.org examples use it. For LLM citation, JSON-LD is how you tell the models "this page is a definition of X" with minimum ambiguity.
Why it matters for Black Box
Every page on www.web4guru.com ships JSON-LD — Organization, WebSite, Article, DefinedTerm, FAQ, BreadcrumbList, depending on the page. The glossary you are reading right now uses DefinedTerm + BreadcrumbList; the blog uses BlogPosting; the pricing page uses Product.
