A schema markup generator builds the JSON-LD code that tells search engines what your page is about in a language they read directly. The generator below assembles valid structured data in your browser from the fields you fill in, so you can copy the result straight into your page without writing any code by hand.
What Schema Markup Is, and Why JSON-LD
Schema markup is a set of tags from the Schema.org vocabulary that label the parts of your page: this is the headline, this is the author, this is the business name, this is the logo. Search engines read those labels to understand the page instead of guessing from the text alone. That understanding is what lets them show rich results such as star ratings, article bylines, and site search boxes. JSON-LD is one way to write that markup. It keeps all the data in a single block of code, separate from the visible content, which is why it is the format Google recommends and the format this tool produces.
How to Use This Schema Generator
- Choose the schema type that matches your page: Article, Organization, WebSite, or LocalBusiness.
- Fill in the fields that apply. The tool uses only the ones the chosen type needs and skips the rest.
- Copy the JSON-LD block the tool shows. Empty fields are left out, so the output stays valid.
- Paste the block into the head or body of your page, or into your content management system’s schema field.
- Run the result through Google’s Rich Results Test to confirm it is valid before you publish.
The Common Schema Types
| Type | What it is for |
|---|---|
| Article | A blog post, news story, or guide. Carries the headline, author, image, and publisher so search engines can show a proper byline. |
| Organization | A company or brand. Carries the name, URL, and logo, and helps the brand appear in a knowledge panel. |
| WebSite | The site as a whole. Carries the name and URL, and can declare a SearchAction so Google may show a site search box. |
| LocalBusiness | A business with a physical presence. Carries the name, URL, image, and description, the base for local result features. |
Validating Your Schema
Generating the markup is only half the job. Before you rely on it, paste the code or the live URL into Google’s Rich Results Test, which reports whether the markup is valid and which rich results it qualifies for. The Schema.org validator catches structural errors in any type. Two rules keep you out of trouble: every value in the markup must match what a visitor actually sees on the page, and you should mark up only content that is present. Markup that describes things not on the page can be treated as a violation.
When to Use It
Add schema markup whenever a page has a clear identity a search engine can act on. Use Article on posts and guides so they can show an author and date. Use Organization on your about or home page so your brand details are explicit. Use WebSite once for the whole site to declare your name and an optional site search. Use LocalBusiness on the page for a business with an address or service area. A page can carry more than one type when it represents more than one thing, for example an Article that also names its publishing Organization.
Last Thoughts on Generating Schema Markup
Structured data is how you stop a search engine from guessing what your page means and tell it directly. The work was never the concept; it was writing correct JSON-LD by hand and keeping it valid. A generator removes that step: you supply the facts, it produces markup that follows the Schema.org rules, and you paste it in.

Key Takeaways:
- Schema markup labels the parts of your page so search engines understand it instead of guessing.
- JSON-LD is the format Google recommends; it sits in the head or body and is invisible to visitors.
- Match the type to the page: Article for posts, Organization for the brand, WebSite for the whole site, LocalBusiness for a physical business.
- This generator runs in your browser and includes only the fields you fill in, so the output stays valid.
- Every value in the markup must match what visitors actually see on the page.
- Always confirm the result in Google’s Rich Results Test before you publish.
Frequently Asked Questions (FAQs)
What is schema markup?
Schema markup is structured data that uses the Schema.org vocabulary to label the parts of a page, such as the headline, author, or business name. Search engines read those labels to understand the page directly, which can qualify it for rich results like bylines, ratings, and site search boxes.
What is JSON-LD?
JSON-LD is a format for writing schema markup that keeps all the data in a single block of code, separate from the visible content of the page. It is the format Google recommends because it is easy to add, easy to maintain, and does not change what a visitor sees.
Where do I put the JSON-LD code?
You place the JSON-LD block in the head or the body of the page. Most content management systems also have a field for custom code or structured data where you can paste it. Wherever it sits, it is read by search engines and stays invisible to visitors.
Does this generator send my data anywhere?
No. The JSON-LD is built entirely inside your browser from the fields you fill in, and nothing is transmitted, logged, or stored on a server. You can confirm this by disconnecting from the internet and watching the tool still produce the markup.
How do I check my schema is valid?
Paste the generated code or your live page URL into Google’s Rich Results Test, which reports whether the markup is valid and which rich results it qualifies for. The Schema.org validator is a second check for structural errors in any schema type.
Which schema type should I use?
Match the type to the page. Use Article for posts and guides, Organization for your brand or about page, WebSite once for the whole site, and LocalBusiness for a page about a business with an address or service area. A page can carry more than one type when it represents more than one thing.
