Build valid schema.org structured data without writing a line of code. Pick a schema type, fill in a friendly form, and watch clean JSON-LD appear live as you type — ready to copy, download, or paste as a script tag. Everything is validated and generated in your browser, so nothing you enter is ever uploaded.

How to use this tool

  1. Choose a schema type

    Select the type of content you want to mark up — Article, Product, FAQ, HowTo, LocalBusiness, Event, Recipe, and more. Each type shows a form tailored to that schema.

  2. Fill in the form

    Enter your details in the friendly fields. Use "Load example" to see a correct, filled-in sample, and add or reorder repeatable items like FAQ questions or HowTo steps.

  3. Watch it validate live

    The JSON-LD updates on every keystroke. Required-field warnings, bad dates, and invalid URLs are flagged inline and in a summary, so a broken object never looks valid.

  4. Copy or download

    Copy the raw JSON, copy the ready-to-paste <script type="application/ld+json"> tag, or download a .json file — then add it to your page and test with Google's Rich Results Test.

Frequently Asked Questions

What is schema markup?

Schema markup is structured data you add to a web page to help search engines understand its content. Written as JSON-LD, it describes things like articles, products, and FAQs in a machine-readable format. Search engines use it to show rich results — such as star ratings, FAQ dropdowns, and other enhanced listings.

Where do I put the JSON-LD on my page?

Place the JSON-LD inside a script tag with type "application/ld+json" in your page's HTML. Either the head or the body works, and Google treats both the same way. This generator gives you the complete script tag with the Copy button, so you can paste it straight into your template or CMS.

Does schema markup improve my Google ranking?

Schema markup does not directly improve your Google ranking, because Google has confirmed it is not a ranking factor. What it does is make your pages eligible for rich results, which can raise click-through rates by making your listing more prominent. Higher clicks can help indirectly, but the markup itself is not a ranking boost.

Is it safe to use an online schema generator?

Yes, this schema generator is safe because it runs entirely in your browser. Nothing you type is uploaded to a server — the JSON-LD is built locally on your own device. That matters when your markup includes business details, event locations, or author names you would rather not hand to a third party.

Do I need coding skills to use it?

No, you do not need coding skills to use this tool. Fill in the friendly form and it writes valid JSON-LD for you, then hands you a copy-and-paste script tag. Basic familiarity with editing your site's HTML, or pasting a code snippet into a CMS field, is all that is required.

How do I test my structured data?

Test your structured data with Google's Rich Results Test or the schema.org validator. Paste the generated JSON-LD or your live URL into either tool to confirm it is valid and see which rich results it qualifies for. This generator also flags missing required fields and bad formats as you type.
