Build valid Schema.org JSON-LD for common types — Organization, Local Business, Website, Article, Product, FAQ, Breadcrumb, Person, Event, Recipe, Review, and Video — ready to paste into your page.
Pro tip: Always run the copied JSON-LD through Google's Rich Results Test before publishing to confirm it's valid.
Search engines understand a page better when you label its parts explicitly: this is a recipe, that is the cook time, here is the author. Schema.org is the shared vocabulary for those labels, and JSON-LD is the format Google recommends for declaring them.
Hand-writing JSON-LD is fiddly — one stray comma or mismatched bracket and the whole block is ignored. This generator lets you choose a type, fill in plain fields, and receive a structurally valid object instead of wrestling with the braces yourself. It also adds the right nested objects for you, such as wrapping an author in a Person and an address in a PostalAddress.
You select a type and the form shows the relevant fields for it; as you fill them in, the tool emits a JSON-LD object with the correct @context and @type and your values mapped to the right properties. It runs entirely in your browser, so no data leaves the page.
Optional fields are only included when you complete them, and the tool builds the nested structures Google expects — a LocalBusiness address becomes a PostalAddress with optional GeoCoordinates, a Product can carry an Offer and an AggregateRating, and an FAQ page becomes a mainEntity array of Question and Answer pairs. The output is wrapped in a <script type="application/ld+json"> block ready to paste into the head or body.
Organization or Local Business markup belongs on a homepage or contact page to establish who you are; a storefront adds an address and opening hours. Article and Person suit a blog, pairing a post with its author. Product, Offer, and Review markup describe an item and its price and rating on a commerce page.
Breadcrumb List is the most dependable SERP enhancement of the set when a page has a clear navigation path. FAQ Page is different: the markup is still valid and useful as metadata on a page that genuinely has questions, but Google now shows the expandable FAQ rich result almost exclusively for well-known government and health sites, so do not add it expecting one. Event, Recipe, and Video Object are for pages built around those exact things — a listing, a dish, or an embedded video — where the structured fields mirror what visitors already see.
The most damaging mistake is marking up content that is not visible on the page — inventing FAQ answers, a star rating, or an event date that a visitor never sees. Google treats that as a structured-data violation and may apply a manual action, so every value must reflect the real, on-page content.
Other frequent slips are choosing a type that does not match the page, leaving out a required property so the block is incomplete, and adding ratings to a Product that has no genuine reviews. When in doubt, mark up less, but mark it up truthfully.
Valid markup makes a page eligible for rich results, but eligibility is not the same as display. Google decides per query whether to show a rich result, and it can ignore markup that contradicts the visible page content or violates its structured-data policies.
The generator validates structure, not truthfulness: it will happily encode a review rating or an event date that does not match your page. Make sure every value genuinely reflects what visitors see, and validate the final block in Google's Rich Results Test before publishing. Privacy note: the fields you enter are processed in your browser and never uploaded.
Input: Type: Organization | name: Acme Tools | url: https://acme.example | logo: https://acme.example/logo.png
Output: A script block containing {"@context":"https://schema.org","@type":"Organization","name":"Acme Tools","url":"https://acme.example","logo":"https://acme.example/logo.png"}.
The @context and @type are added automatically so the object is valid.
Input: Type: FAQ Page | Q1: Do you offer refunds? A1: Yes, within 30 days. | Q2: Is there a free trial? A2: Yes, 14 days, no card required.
Output: A FAQPage object with a mainEntity array of two Question entries, each holding an acceptedAnswer — the standard Schema.org FAQ structure. Note that Google now shows FAQ rich results almost only for well-known government and health sites.
Only mark up questions and answers that are actually visible on the page.
Input: Type: Product | name: Trail Runner 2 | brand: Acme | price: 89.00 | priceCurrency: USD | availability: InStock | ratingValue: 4.6 | reviewCount: 218
Output: A Product object with a nested Offer (price, currency, InStock) and an AggregateRating carrying ratingValue 4.6 across 218 reviews.
Add the rating only if those reviews genuinely appear on the page.
JSON-LD, the format Google recommends. It lives in a single script block and keeps the structured data separate from your visible HTML.
Twelve common ones: Organization, Local Business, Website, Article, Product, FAQ Page, Breadcrumb List, Person, Event, Recipe, Review, and Video Object.
No. Valid markup makes a page eligible, but Google chooses per query whether to show a rich result and may skip markup that conflicts with the page.
Inside the page, commonly in the head or just before the closing body tag. Either location is fine as long as the block appears on the relevant page.
Yes. Generate each type and include multiple script blocks, but only describe content that genuinely appears on that page to stay within Google's guidelines.
Run the generated block through Google's Rich Results Test or the Schema.org validator to catch any property warnings before you publish.
I document how each check works, where its data comes from, and which parts are only estimates.
