Validate your JSON-LD structured data. Checks for valid JSON, @context, @type, and displays the parsed structure or error messages.
Paste a JSON-LD snippet — the contents of a <script type="application/ld+json"> block — and the validator checks it in three steps: is it valid JSON at all, does it declare an @context (usually schema.org), and does it declare an @type such as Product, Article, or FAQPage. If the syntax is broken, you get the parse error; if it passes, you see the parsed structure laid out so you can confirm the fields are what you intended.
It is a quick sanity check before you ship: a single missing comma or stray trailing bracket silently invalidates the whole block, and search engines simply ignore malformed structured data rather than warning you about it.
JSON-LD is how you describe your content to search engines in a machine-readable way. Valid structured data makes your pages eligible for rich results — star ratings, FAQ dropdowns, breadcrumbs, product prices, and event details shown directly on the results page. Those enhanced listings take up more space and tend to earn more clicks than a plain blue link, which is why structured data is a standard part of technical SEO. Because the markup ships inside your HTML, it works best on pages rendered on the server (see SSR and SSG), where crawlers see the complete document on first load — the same property that makes fast-loading pages good for both rankings and conversions.
Not directly — structured data is not a ranking factor. What it does is make your pages eligible for rich results, which are more visually prominent and typically get higher click-through rates. More clicks from the same ranking position is usually the practical win.
Inside a script tag with type="application/ld+json", placed anywhere in the head or body of the page. The head is conventional. Each page should carry structured data describing its own content — a product page gets Product markup, an article gets Article markup.
Both express schema.org structured data, but microdata is woven into your HTML attributes while JSON-LD lives in a single self-contained script block. Google recommends JSON-LD because it is easier to write, maintain, and validate without touching your page markup.
