Schema markup generator — JSON-LD for articles, FAQs, products, and reviews

This free schema markup generator helps you produce valid JSON-LD using the Schema.org vocabulary—ideal for technical SEO, content publishing, and ecommerce. Build Article and editorial markup, FAQPage for question hubs, Product with offers, Review with ratings, Organization for brand panels, and BreadcrumbList for navigation trails. Everything runs locally: copy, download, or upload an existing file to refine. Pair output with the Open Graph tag generator for social metadata, the meta title and description checker for SERP snippets, and the XML sitemap generator so discovery aligns with your structured data.

Article / BlogPosting

Output updates when you change the schema type or fields. Toggle “Wrap in script tag” for HTML paste.

Why structured data matters for SEO

Search engines use structured data to understand entities—who wrote a piece, what a product costs, which crumbs belong in a trail, and whether a page is a FAQ hub. JSON-LD keeps that signal separate from HTML, which simplifies CMS workflows and theme updates. While rich results are never guaranteed, clear schema markup improves eligibility for enhancements shown in Search and helps knowledge panels and assistants reason about your brand when combined with consistent Organization and sameAs links.

Teams often search for FAQ schema generator, product schema JSON-LD, and article schema markup when migrating platforms or launching content programs. This tool focuses on copy-ready blocks you can paste beside templates generated by the robots.txt generator and crawl rules, so technical SEO stays coherent end to end.

How to use this JSON-LD generator (step by step)

  1. Choose the schema type that matches the primary entity on the URL. Do not stack unrelated types purely for visibility; align with what users see on the page.
  2. Enter HTTPS URLs for canonical pages, images, and offers. Use ISO-8601 timestamps for dates when possible so parsers are unambiguous.
  3. For FAQPage, write questions and answers that appear verbatim in the UI—FAQ markup must reflect visible content, not hidden keyword blocks.
  4. Click Copy or Download. Enable Wrap in script tag if your CMS expects a full application/ld+json snippet. Use Upload to load saved JSON or an exported script block; we try to detect @type and switch tabs.
  5. Validate with Google Rich Results Test after deploy, then monitor Search Console enhancements. For on-page copy quality, run the readability checker and keyword density checker.

Keywords and topics covered by each preset

Article covers headline, description, image, author, publisher, and modified dates—aligned with editorial SEO for blogs and guides. FAQPage maps to help centers and support articles. Product combines SKU, brand, and Offer pricing for storefronts. Review emits Rating stars for testimonials. Organization supports logo and social profiles via sameAs. BreadcrumbList expresses hierarchy for category and detail URLs—often paired with visible breadcrumbs in the UI.

Internal tools that complement schema markup

Structured data works best when titles, descriptions, and URLs are consistent. Before launch, verify snippet lengths with the meta title and description checker, generate campaign tracking with the UTM link builder, and confirm redirects with the redirect type checker. Multilingual sites can pair JSON-LD with the hreflang tag generator for language clusters.

Frequently asked questions

What is schema markup and why use JSON-LD?
Schema markup is structured vocabulary from Schema.org that describes entities on a page—articles, products, FAQs, reviews, and more. JSON-LD is the recommended format for Google: you embed a JSON object in a script tag with type application/ld+json so crawlers can read entities without changing visible HTML.
Does this tool send my content to your servers?
No. All fields are merged into JSON-LD in your browser. Copy and download use local APIs. Upload reads a file with the File API in your tab only—nothing is uploaded to us for processing.
How do I add the output to my site?
Paste the JSON inside a script tag: <script type="application/ld+json">{ ... }</script>—usually in the page head or before closing body. Use one JSON object per script, or combine multiple entities in a @graph array under a single @context if you prefer one block.
Will schema guarantee rich results?
No. Structured data is eligibility, not a promise. Google selects rich results based on quality, policies, and query context. Always validate with Rich Results Test and monitor Search Console enhancements reports.
What is the difference between Article, BlogPosting, and NewsArticle?
They share many properties. BlogPosting extends Article for blogs; NewsArticle is for news with stricter publisher expectations. Pick the type that best matches your content and editorial standards.
How do FAQ rich results relate to on-page FAQs?
FAQPage markup should reflect content that is visibly present on the page. Do not create FAQ markup solely for search if users cannot see the same questions and answers—this violates spam policies.
Which tools pair with schema and on-page SEO checks?
Use the meta title and description checker for snippets, the Open Graph tag generator for social cards, the XML sitemap generator for discovery, and the robots.txt generator for crawl rules. Together they cover technical SEO around your structured data.
Can I merge Product and Review markup?
Yes. A common pattern is Product with nested review properties or separate Review entities that reference the product URL. This generator outputs one block at a time—combine objects carefully or use @graph in a single script after export.
