Free schema markup generator that runs in your browser. No sign-up, no install.
Schema Markup (JSON-LD) Generator
Fill in only what is true for your page. Empty fields are left out of the output.
<script type="application/ld+json">
{
"@context": "https://schema.org",
"@type": "Organization"
}
</script>What this tool does and who it is for
Pick a schema.org type, fill in the facts that are true for your page, and the tool builds JSON-LD you can paste into the head of the page. Empty fields are left out, so you never publish placeholder values.
AggregateRating is only included for Product and SoftwareApplication, and only when you enter both a real average and a real review count. Nothing is prefilled.
Official Formula / Technical Standard
Real-World Worked Scenario
Enter your target URL and parameters to produce standard-compliant markup and tracking directives.
When people use it
Organization markup for a homepage
Add your name, logo and profile URLs so search engines can connect the entities.
Article markup for blog posts
Provide headline, author, image and dates that match the visible page.
Local business details
Enter your address and phone exactly as they appear on the page.
Notes for US users
- LocalBusiness addresses are emitted with addressCountry US. Edit the JSON if you are elsewhere.
- Markup should describe content visible on the page. Hidden or misleading markup can lead to manual actions.
Limits and what to double-check
- •Google shows FAQ rich results only for well-known government and health sites, and has stopped showing HowTo rich results. The markup stays valid but will not create a special result.
- •The generator does not validate against every Google feature requirement. Run the Rich Results Test before publishing.
- •Review ratings must come from real, visible reviews. Self-written ratings violate Google's policies.
Expert Best Practices & Common Pitfalls
Recommended Best Practices

Frequently Asked Questions
How does the Schema Markup Generator work?▼
The Schema Markup Generator runs 100% inside your web browser using modern client-side JavaScript. It performs calculations, conversions, and document processing locally on your device without sending any data to external servers.
Is this schema markup generator completely free to use?▼
Yes. This tool is completely free with no usage limits, no subscriptions, and no registration required.
Is my data private when using the Schema Markup Generator?▼
Yes. Because all operations execute locally on your computer or phone, your inputs, documents, and data never leave your browser.
Where do I put the JSON-LD?▼
Inside a script tag of type application/ld+json in the head or body of the page. The output already includes the script tag.
Why was my rating left out?▼
It is emitted only when both rating and review count are above zero. This prevents made-up ratings from slipping in.
Does schema improve rankings?▼
Not directly. It helps search engines understand the page and can make you eligible for some rich results.
Can I add several types to one page?▼
Yes. Generate each block separately and add each in its own script tag, or combine them in a JSON array.
