What is JSON-LD schema markup and does Google prefer it?

JSON-LD is a way to describe your page's data (a business, article, product, FAQ) in a machine-readable block placed in the HTML. Google's own documentation names JSON-LD as its recommended structured-data format because it sits in one script tag and does not tangle with your visible markup.

How do I add FAQ schema to my website?

Pick the FAQPage type above, add each question and its answer, then copy the generated block into the of the page that already shows those same questions. Google requires the FAQ content to be visible on the page, do not add answers that users cannot see.

What is the difference between schema.org and Google structured data?

schema.org is the shared vocabulary, the list of types like LocalBusiness and their property names. Google structured data is Google's subset of that vocabulary, with its own required and recommended properties for each rich result. This tool follows schema.org for casing and nesting, and Google's feature docs for the validation checklist.

Which schema types get rich results in Google Search?

The eight types here all map to documented Google features: LocalBusiness (business panel), Article (top-stories and headline), Product (price and rating), FAQPage (expandable questions), BreadcrumbList (the trail above your title), Event, Organization and Person. Eligibility is still Google's call, valid markup makes you eligible, not guaranteed.

Where do I paste JSON-LD structured data: head or body?

Either works for Google, but the is the convention and keeps it out of your visible content. Paste the whole block, including the script tags. If your CMS strips script tags, look for a dedicated header-code or SEO field.

Is my data sent to a server?

No. The generator builds the JSON-LD entirely in your browser with JavaScript, nothing is uploaded, logged, or stored. You can disconnect from the internet and it still works. This matters when the markup contains a phone number, address, or unpublished event details.

Will this guarantee I win a rich result?

No tool can. Valid structured data makes a page eligible, but Google decides whether to show a rich result based on content quality, policy compliance, and the query. Use the Rich Results Test link to confirm your markup is error-free, then publish and monitor Search Console over the following weeks.

Why are some properties left out of the output?

The generator omits any field you leave blank rather than emitting an empty value. Empty or null properties are noise that some validators flag, so a minimal, valid block is safer. Fill more fields to enrich the output, the checklist shows which recommended properties are still missing.

How were the required and recommended fields decided?

The per-type checklist follows Google Search Central's feature documentation, cross-checked against the schema.org vocabulary. The lists were last verified on 2026-07-09; Google revises them occasionally, so the checklist is reviewed on that date and re-checked when Google announces changes.

How it works

Structured data is a small, machine-readable summary of what a page is about. Search engines read it to understand your content and to decide whether the page qualifies for a rich result, the star ratings, FAQ drop-downs, business panels and breadcrumb trails you see in Google. This generator produces that summary in JSON-LD, the format Google names as its recommended syntax in the Introduction to structured data guide.

It is a serializer, not a numeric calculator. For the type you select it maps each form field to the correct schema.org property and builds a JSON object, then pretty-prints it with JSON.stringify. Because the JSON is assembled from real objects rather than glued together as text, every quote, backslash and newline in your input is escaped correctly. It is not possible to produce a broken block by typing an awkward character. The four rules it follows:

Envelope. Every block opens with "@context": "https://schema.org" and the chosen @type, exactly as schema.org requires.
Correct nesting. Compound values become their own typed objects, an address is a PostalAddress, opening hours are OpeningHoursSpecification entries, and an author is a nested Person. Day names and availability become full schema.org URLs.
Omission. Any field you leave blank is dropped entirely, the output never contains an empty string, a null, or a half-filled object. This keeps the block minimal and avoids validator warnings.
Auto-numbering. BreadcrumbList positions are assigned 1, 2, 3… from the order of your rows, so you never hand-number them.

The live checklist below the form compares the block it just built against Google's documented required and recommended properties for that type, green when satisfied, amber for a missing recommended field, red for a missing required one. As a final cross-check the tool round-trips the output through JSON.parse and confirms the @context, showing a “Valid JSON verified” badge only when the block parses cleanly. Structural validity is guaranteed here; whether Google then awards a rich result depends on your content and its own policies.

Worked examples

LocalBusiness, a Colombo bakery

name + address + one grouped opening-hours block

"@type": "LocalBusiness",
"name": "Sena Bakery",
"telephone": "+94112345678",
"address": { "@type": "PostalAddress",
  "streetAddress": "42 Galle Road",
  "addressLocality": "Colombo", "addressCountry": "LK" },
"openingHoursSpecification": [{ "@type": "OpeningHoursSpecification",
  "dayOfWeek": [".../Monday", ".../Tuesday", ".../Friday"],
  "opens": "06:30", "closes": "19:00" }]

Checklist: name ✓ required; address, telephone and hours ✓ recommended. Validates as a LocalBusiness.

FAQPage, the omission rule in action

two filled Q&As, a third row left blank

"@type": "FAQPage",
"mainEntity": [
  { "@type": "Question", "name": "Is the tool free?",
    "acceptedAnswer": { "@type": "Answer",
      "text": "Yes, completely free with no signup." } },
  { "@type": "Question", "name": "Where do I paste it?",
    "acceptedAnswer": { "@type": "Answer",
      "text": "In the <head> of your page." } }
]

The empty third row is dropped, so mainEntity has 2 questions, not 3, the required check passes because at least one has an answer.

BreadcrumbList, auto-numbered positions

three crumbs, positions assigned automatically

"@type": "BreadcrumbList",
"itemListElement": [
  { "@type": "ListItem", "position": 1, "name": "Home",
    "item": "https://induwara.lk" },
  { "@type": "ListItem", "position": 2, "name": "Tools",
    "item": "https://induwara.lk/tools" },
  { "@type": "ListItem", "position": 3, "name": "Schema Generator",
    "item": "https://induwara.lk/tools/schema-markup-generator" }
]

Positions run 1 → 3 from row order. Delete the middle crumb and the remaining two renumber to 1 and 2.

Supported types

Version 1 covers the eight types that map to documented Google rich results. Niche types (Recipe, JobPosting, Course, Video) are planned for a later version.
