Generate valid JSON-LD schema markup for free: pick a type, fill in the form and copy the code into your page. This schema markup generator checks required fields as you type and runs entirely in your browser, with no sign-up.
What is a schema markup generator?
A schema markup generator is a tool that writes structured data in JSON-LD, the format Google recommends, from a simple form, so you don’t have to hand-code schema.org properties. The markup tells search engines and AI assistants exactly what a page describes (a business, an article, a product or an event) and can make the page eligible for rich results. This generator covers Local Business, Organization, Article, FAQ, Product, Review, Event and Breadcrumb markup and flags missing or invalid fields before you publish.

How to Use the Schema Markup Generator
- Pick a schema type.
Choose the type that matches what the page is about, for example Local Business for your contact page or Article for a blog post.
- Fill in the fields.
Required fields are marked with an asterisk. The JSON-LD updates as you type, and the checker lists anything missing or invalid.
- Copy or download the code.
Copy it with the script tag included, or download a .json file. Your entries are saved in this browser, so you can come back and edit them.
- Add it to your page.
Paste the script block into the page’s <head>, or into a Custom HTML block in WordPress. A header-code plugin such as WPCode also works.
- Test before you publish.
Click “Test in Google” to open the Rich Results Test with your code already copied, then paste it on the Code tab.
Why Schema Markup Matters
Schema markup tells Google and AI answer engines exactly what’s on a page: a business’s address and hours, an article’s author and date, a product’s price and stock status, or an event’s date and venue. Without it, search engines have to infer those details from the visible text. With it, pages can become eligible for rich results such as product prices, review stars, event listings and business details, and it gives AI tools clear facts to quote when they answer a question.
Which Schema Type Should You Use?
- Local Business: for the homepage or contact page of a business with a location or service area.
- Organization: for your homepage or About page, to connect your name, logo and social profiles.
- Article: for blog posts and news, to describe the headline, author and publish date.
- FAQ: for pages with a genuine question-and-answer section. Google retired FAQ rich results for all sites on 7 May 2026, but the markup is still valid and helps AI tools and other search engines read your Q&A.
- Product: for product pages, to show price, availability and ratings.
- Review: for a page reviewing a specific product, book, course or piece of software. Google doesn’t show stars for reviews a business writes about itself.
- Event: for concerts, workshops, webinars and other events with a date, in person or online.
- Breadcrumb: for any page, to show its position in your site’s structure.
How to Test Your Schema After You Add It
Generating the code is only half the job. After you paste it into your page, check that search engines can read it and that it matches what visitors see. Work through these checks in order:
\nFastest check: paste the code into our free Schema Validator, which flags syntax errors, unknown properties and the fields Google requires before you open the Rich Results Test.
- Rich Results Test. Paste your URL into Google’s Rich Results Test to see which Google rich result types the page is eligible for, with errors and warnings for each.
- Schema Markup Validator. Use validator.schema.org to check the general schema.org syntax, including types Google does not show as rich results.
- URL Inspection. In Search Console, inspect the live URL to confirm Google can fetch the page with the markup in place.
- Enhancements reports. After Google recrawls the page, the matching report in Search Console (for example Products or Breadcrumbs) lists valid and invalid items across the site.
The most common problems are a missing required property, a date not in ISO 8601 format, and markup describing content that is not visible on the page, which Google’s structured data policies do not allow. Also watch for duplicates: if an SEO plugin already outputs Article or Organization markup, do not paste a second copy. Our step-by-step schema markup validator guide shows each check with examples, and our technical SEO service can audit structured data across your whole site.
Frequently Asked Questions
Do I need to know how to code to use this?
No. Fill in the form in plain language and the tool writes valid JSON-LD for you. You only need to paste the result into your site.
Where exactly do I paste the code?
Inside the <head> section of the page it describes, or anywhere in the page body. In WordPress, a Custom HTML block or a header-code plugin such as WPCode lets you add it without editing theme files.
Does adding schema markup guarantee rich results in Google?
No. Valid markup makes a page eligible for rich results; Google still decides case by case whether to show them. Accurate markup that matches the visible page content gives you the best chance.
Is my data uploaded anywhere?
No. Everything you type stays in your browser, and the JSON-LD is generated locally. Your entries are saved in your browser’s local storage so you can return to them, and “Clear form” removes them.
Can I add more than one schema type to the same page?
Yes. Generate each type separately and add both script blocks to the same page, for example an Article plus a Breadcrumb on a blog post.
