Schema.org JSON-LD Generator

Q: Does adding schema guarantee rich results?

No. Structured data makes your content eligible for rich results, but Google decides whether to show them based on page quality, domain authority, content relevance, and user context.

Q: Where should I place the JSON-LD script?

Google recommends placing JSON-LD in the head section, but anywhere in body also works. For SPAs or dynamically-rendered pages, ensure the script is present in the server-rendered HTML.

Q: Can I use multiple schema types on one page?

Yes. A product page typically has Product, BreadcrumbList, Organization, and possibly AggregateRating. Use separate script blocks or link them with @id references.

Q: How do I test my structured data?

Use Google's Rich Results Test for types that produce rich snippets. For general validation, the Schema Markup Validator at validator.schema.org catches syntax errors.

Q: What's the difference between JSON-LD and microdata?

Google strongly recommends JSON-LD. It's a standalone JSON block that doesn't interleave with HTML, making it easier to generate, validate, and maintain.

Build valid structured data for articles, products, local businesses, FAQs, events, courses and more. Copy ready-to-paste JSON-LD — no signup, no tracking, everything runs in your browser.

What is JSON-LD structured data?

JSON-LD (JavaScript Object Notation for Linked Data) is Google's recommended format for adding structured data to web pages. It's a block of JSON you place in your HTML that tells search engines exactly what your content is — an article, a product, a local business, a recipe, a video — and the relationships between its parts.

When search engines understand your content's structure, they can show rich results: star ratings in product listings, FAQ accordions below your result, recipe cards with photos and cook times, event dates, job postings, and more. Rich results consistently get higher click-through rates than plain blue links.

Most valuable schema types for SEO

Not all schema types are equal for organic search. These produce the most visible rich results:

Schema type	Rich result	Best for
FAQPage	Expandable Q&A under result	Help pages, support docs, landing pages
Product	Price, availability, star rating	E-commerce product pages
Article	Carousel in Google Discover, news carousels	Blog posts, news, editorial content
LocalBusiness	Map pack, knowledge panel, hours	Physical stores, restaurants, services
Recipe	Photo, rating, calories, cook time	Food blogs, cooking sites
HowTo	Step-by-step carousel	Tutorials, guides, DIY content
Event	Date, venue, ticket info in results	Concerts, conferences, meetups
BreadcrumbList	Clickable path under page title	Any site with hierarchical navigation
VideoObject	Video thumbnail, duration, upload date	Video pages, embedded content
Organization	Knowledge panel on brand search	Company homepages

The five mistakes that kill rich results

Invisible content. Data in JSON-LD must match visible content on the page. Adding a fake 5-star rating or a price that doesn't exist on the page is a violation and can get your structured data manually demoted.
Missing required properties. Google marks a type as eligible for rich results only if certain required fields are present. An Article without headline or image won't qualify.
Wrong types. Using Article for a product page or Product for a service page creates confusion. Each schema type has a specific semantic purpose.
Invalid URLs. Image URLs, logo URLs, and canonical links must be absolute (start with https://) and return a 200 response. Relative paths and broken links are the #1 validation failure.
Testing on production only. Always validate with Google's Rich Results Test before deployment, then re-test after each major template change.

How this generator works

Pick a schema type from the list, fill in the required fields, and the tool assembles a valid JSON-LD block with the correct @context, @type, and nested structures. Optional nested types (like Person for an author or Offer for pricing) only appear in the output when you actually fill them in — no empty objects cluttering your markup.

The validator checks required fields, URL format, and Google's published recommendations for each type. Warnings never block generation — they're guidance, not errors. Copy the JSON-LD, paste it into your page's <head>, and verify with Google's Rich Results Test.

Frequently asked questions

Does adding schema guarantee rich results?

No. Structured data makes your content eligible for rich results, but Google decides whether to show them based on page quality, domain authority, content relevance, and user context. Schema is necessary but not sufficient. That said, sites with correct structured data consistently see higher CTRs even when rich snippets aren't always displayed.

Where should I place the JSON-LD script?

Google recommends placing JSON-LD in the <head> section, which keeps markup cleanly separated from content. However, placing it anywhere in <body> also works — Google's crawler reads the whole document. For SPAs or dynamically-rendered pages, ensure the script is present in the server-rendered HTML, not just injected client-side.

Can I use multiple schema types on one page?

Yes — and you should. A product page typically has Product, BreadcrumbList, Organization, and possibly AggregateRating. An article page often combines Article + Person (author) + Organization (publisher) + BreadcrumbList. Use separate script blocks or link them with @id references. Avoid duplicating data in multiple types.

How do I test my structured data?

Use Google's official Rich Results Test for types that produce rich snippets (Article, Product, FAQ, Recipe, HowTo, etc.). For general validation, the Schema Markup Validator at validator.schema.org catches syntax errors. Google Search Console's "Enhancements" reports show structured data status across your entire site once deployed.

What's the difference between JSON-LD and microdata?

All three formats (JSON-LD, microdata, RDFa) are supported by schema.org, but Google strongly recommends JSON-LD. It's a standalone JSON block that doesn't interleave with HTML, making it easier to generate, validate, and maintain. Microdata and RDFa are embedded directly in HTML attributes, which couples structure with presentation and makes updates painful.

Is my schema data sent to any server?

No. All generation, validation, and exports happen locally in your browser using JavaScript. Your form data, generated JSON, and downloaded files never leave your device. The tool works fully offline once loaded.
