Schema Markup Generator — Free JSON-LD Structured Data Tool
The free Schema Markup Generator creates valid JSON-LD structured data for eight schema types in seconds. Fill a form, copy the output, and paste it into your page head — no coding required, no signup, runs entirely in your browser.
Why Schema Markup Matters for SEO
Search engines read the text of a page, but structured data gives them explicit, machine-readable facts. A product page might say "$49.99" in its body copy, but without a Product schema, Google has to guess that this is a price rather than a phone number or a zip code. Schema markup removes that ambiguity.
The practical payoff is rich results — enhanced search snippets that display star ratings, product prices, FAQ dropdowns, event dates, and breadcrumb trails directly in the search listing. Rich results consistently achieve higher click-through rates than standard blue links because they surface more information before the user clicks.
Beyond rich results, structured data is increasingly important for AI-powered search surfaces. AI-generated answers pull structured facts more reliably than unstructured prose. A page with accurate Organisation or Article schema is easier to cite accurately in AI summaries than one with identical text but no markup.
How to Use the Schema Markup Generator
- Open the Schema Markup Generator. The tool opens on the Article type by default with an empty form and an empty JSON-LD output panel.
- Click a schema type in the type picker — Article, Product, FAQPage, LocalBusiness, Organization, WebSite, Event, or BreadcrumbList. The form updates immediately with the fields for that type.
- Fill in the form fields. Fields marked with an asterisk are required for a minimal valid schema. All other fields are optional — empty fields are automatically omitted from the output so the JSON stays clean.
- The JSON-LD output panel on the right updates in real time as you type. Review the structure to confirm the values are correct.
- Click Copy to copy the complete JSON-LD block, or Downloadto save it as a
.jsonfile. Paste the copied code inside a<script type="application/ld+json">tag in the<head>of your HTML.
The 8 Supported Schema Types
| Schema type | What it describes | Rich result it can unlock |
|---|---|---|
| Article | Blog posts, news articles, how-to guides | Enhanced article listings with author, date, and publisher in Google News and Discover |
| Product | E-commerce product pages | Price, availability, and star rating in search snippets and Google Shopping |
| FAQPage | Pages with a question-and-answer format | FAQ dropdown in search results showing up to two Q&A pairs beneath the page link |
| LocalBusiness | Physical business locations | Knowledge Panel with address, hours, phone, and map in Google Search and Maps |
| Organization | Company or brand homepage | Knowledge Panel with logo, social profiles, and contact information |
| WebSite | The root page of a website | Sitelinks Searchbox — a search bar inside your Google listing when your domain is queried |
| Event | Conferences, concerts, meetups, online events | Event rich result showing name, date, location, and ticket link |
| BreadcrumbList | The navigation path to a page | Breadcrumb trail beneath the page title in search results instead of a raw URL |
Advanced Workflows
Combining multiple schema types on one page
A single page can include several <script type="application/ld+json"> blocks, each with a different @type. A product page, for example, benefits from both a Product schema (for the price and rating rich result) and a BreadcrumbList schema (so the URL shows as a readable path in search instead of a raw slug). Generate each type separately in the tool, copy both outputs, and add two distinct script tags to your page head.
Using FAQPage schema to capture more SERP space
Google expands FAQ rich results directly in the search listing, showing up to two question-and-answer pairs beneath the page link. This can nearly double the vertical space your result occupies on the page. To qualify, the FAQ content must be genuinely visible on the page — Google will not show FAQ rich results for schema added to content that is hidden, behind a tab, or absent from the page entirely. Write your questions and answers in the tool, then make sure the same content is visible to users in your page body.
LocalBusiness schema for Google Maps pack visibility
When someone searches for a business category near a location — "bakery near me" or "plumber in Austin" — Google can surface a map pack above organic results. LocalBusiness schema strengthens the match between your page and those queries by explicitly declaring your address, telephone, opening hours, and price range in a format Google can parse without inference. Fill every field you can in the LocalBusiness form, including the address sub-fields: street address, city, region, postal code, and countryshould all be present for the most reliable address parsing.
WebSite schema and the Sitelinks Searchbox
The WebSite schema type includes an optional search URL template field. When filled with your site's search URL pattern — for example https://example.com/search?q={search_term_string} — it signals to Google that your site has a functional search feature. Google may then add a search input box directly inside your brand listing in search results. This is only shown for sites Google considers authoritative for their own brand name query, and only when the search target URL is valid.
Validating your output before publishing
The tool generates syntactically valid JSON-LD and strips empty fields, but it does not check whether your values satisfy Google's requirements for each rich result type. For example, Product rich results require at least one of offers, aggregateRating, or review. After generating your schema, paste it into Google's Rich Results Test to confirm your page qualifies for the enhanced display before deploying.
Common Questions
What is JSON-LD and why does Google prefer it?
JSON-LD stands for JSON for Linked Data. It is a way to embed structured data in a web page as a standalone JavaScript object inside a <script> tag, rather than weaving attributes into the page's HTML elements (as Microdata and RDFa do). Google recommends JSON-LD because it is easy to add without modifying page markup, easy to validate, and does not break existing HTML structure. It also works reliably in dynamically rendered pages.
Does schema markup affect page load speed?
No. A JSON-LD block in the page head is a small plain-text file — typically under 2KB — and the script tag carries no executable logic. Crawlers read it at parse time. It has no measurable effect on Core Web Vitals or page load performance.
How do I validate my schema before publishing?
Two tools cover different concerns. Google's Rich Results Test (search.google.com/test/rich-results) confirms whether your schema qualifies for a specific rich result feature. The Schema Markup Validator (validator.schema.org) checks conformance against the full schema.org specification, which is broader than what Google specifically uses. Run both for a complete picture.
Can I use this tool with WordPress or other CMS platforms?
Yes. Copy the JSON-LD block and inject it into your page head using a plugin that supports custom HTML in the head section — "Insert Headers and Footers" is a common choice. Alternatively, SEO plugins such as Rank Math and Yoast SEO generate their own schema markup automatically. The advantage of this generator is that it lets you add schema types those plugins do not support, or override their defaults with more specific values.
Is the data I enter stored anywhere?
No. Everything runs in your browser. Your inputs are never sent to a server. The JSON-LD is generated locally from your form entries, so there is no account, no history, and no data retention.
