Free JSON-LD Schema Markup Generator

Structured data is one of the most powerful yet underused tools in SEO. By adding JSON-LD schema markup to your web pages, you tell search engines exactly what your content is about — and in return, Google can display your pages as eye-catching rich results with star ratings, prices, FAQ dropdowns, recipe cards, event listings, and more.

Our free JSON-LD generator makes it easy to create valid structured data without writing a single line of code. Whether you're a small business owner adding your restaurant to Google, a blogger optimizing article markup, or a developer building e-commerce product pages, this tool handles the technical details so you can focus on what matters.

What is JSON-LD and Why Does It Matter for SEO?

JSON-LD stands for JavaScript Object Notation for Linked Data. It's a standardized format for encoding structured data — essentially metadata about your page's content — using a simple JSON script block placed in your page's HTML.

Unlike older approaches like Microdata or RDFa that require you to weave data attributes into your HTML elements, JSON-LD sits separately in a <script> tag. This separation makes it dramatically easier to implement, maintain, and debug. It's also the format that Google explicitly recommends.

When search engine crawlers encounter valid JSON-LD on your page, they gain a much richer understanding of your content. A product page isn't just "a page with text and images" — it becomes a Product with a specific name, brand, price, availability status, and customer ratings. This understanding directly translates to richer, more informative search result listings.

How Structured Data Helps with Rich Results

Rich results are the enhanced search listings that stand out from standard blue links. They include features like:

Product snippets showing price, availability, and star ratings directly in search results
FAQ dropdowns that expand to show answers right on the results page
Recipe cards with cooking time, calories, and ratings
Event listings with dates, venues, and ticket information
How-to steps displayed as an expandable guide
Job postings that appear in Google's dedicated jobs search
Local business panels with hours, phone, address, and reviews

Pages with rich results typically see significantly higher click-through rates compared to standard listings because they occupy more visual space and provide immediate value to searchers. Adding structured data is one of the few SEO techniques where the technical effort directly translates to measurable improvements in search visibility.

How to Use This Generator

Choose a schema type from the dropdown. Not sure which one? Read the description below each type — it explains when to use it and what Google features it unlocks.
Or start with a template. Click the "Templates" button to load pre-filled data for common scenarios like restaurants, e-commerce products, blog posts, or events. Templates give you a head start and show you exactly what kind of information to enter.
Fill in the form fields. Fields marked with a red asterisk (*) are required for the markup to be valid. Fields tagged "REC" are recommended by Google and improve your chances of getting rich results. All other fields are optional but can provide additional context.
Watch the JSON-LD output update in real-time on the right panel. The validation panel tells you whether your markup is complete and which rich result types you qualify for.
Copy the code and paste it into your website. The generated output includes the full <script type="application/ld+json"> wrapper — paste it directly into your page's <head> section.
Test it. Click "Test in Google Rich Results" to validate your markup with Google's official testing tool and confirm everything looks correct.

Adding the Generated Code to Your Website

Plain HTML

Copy the generated script tag and paste it into your page's <head> section, ideally before the closing </head> tag. That's it — the JSON-LD block is self-contained and doesn't interact with your page's visible content.

WordPress

You have several options: Use a structured data plugin like Yoast SEO, Rank Math, or Schema Pro that handles this automatically. For manual control, add the script tag to your theme's header.php file or use the "Additional Scripts" option available in most themes. Some page builders also offer custom code blocks where you can paste the JSON-LD.

Shopify

Edit your theme's theme.liquid file and paste the JSON-LD script inside the <head> section. Many Shopify themes already include basic Product schema, so check for existing structured data first to avoid conflicts. For product-specific markup, you may want to edit the product.liquid template instead.

Next.js, Astro, and Other Frameworks

Add the JSON-LD as a script tag in your page's head component. Most modern frameworks provide a Head component or equivalent where you can inject the script. Make sure to set the type attribute to application/ld+json and pass the JSON as the script content.

Tips for Better Structured Data

Only mark up visible content. Google requires that structured data reflects content that users can actually see on the page. Don't add markup for content that doesn't exist on the page.
Use specific types. A Restaurant is better than a generic LocalBusiness. A BlogPosting is better than a generic Article. More specific types give Google more context.
Keep it accurate. Misleading structured data (fake reviews, incorrect prices) violates Google's guidelines and can result in a manual penalty.
Test after deployment. Always use Google's Rich Results Test after adding markup to your live site to confirm it's being read correctly.
Monitor in Search Console. Google Search Console has an "Enhancements" section that reports structured data errors and shows which rich results your pages are earning.

Frequently Asked Questions

What is JSON-LD and how is it different from other structured data formats?

JSON-LD (JavaScript Object Notation for Linked Data) is a method of encoding structured data using JSON. Unlike Microdata, which embeds data within HTML tags, or RDFa, which uses HTML attributes, JSON-LD is added as a standalone script block in your page's head section. This makes it easier to implement and maintain because it doesn't require changes to your page's HTML structure. Google recommends JSON-LD as the preferred format for structured data markup.

Will adding structured data guarantee rich results in Google?

No. Adding valid structured data makes your page eligible for rich results, but Google doesn't guarantee they'll appear. Google's algorithms decide which rich results to display based on relevance, page quality, and other ranking factors. However, valid structured data significantly increases your chances of earning rich results and improves how Google understands your content.

How many schema types can I add to a single page?

You can add multiple JSON-LD schema blocks to a single page. For example, a blog post might include an Article schema plus an Organization schema for the publisher and a BreadcrumbList schema for navigation. Each schema type should be in its own script tag. Just make sure every schema accurately describes content that's actually visible on the page.

Do I need structured data on every page of my website?

You don't need structured data on every page, but you should add it to pages where it's relevant. At minimum, add Organization or LocalBusiness schema to your homepage, Article schema to blog posts, and Product schema to product pages. Focus on pages that could benefit from rich results in search — these are the pages where structured data has the most impact on visibility and click-through rates.

Is the generated JSON-LD code saved or sent to any server?

No. This tool runs 100% in your browser using client-side JavaScript. The structured data you create never leaves your computer. Nothing is sent to our servers or any third party. You can verify this by checking your browser's network tab — you'll see no outgoing requests containing your data. Your work is saved in the URL hash so you can bookmark or share it.

How do I add JSON-LD markup to my WordPress site?

There are several ways to add JSON-LD to WordPress: (1) Use a plugin like Yoast SEO or Rank Math that generates structured data automatically. (2) Add the script tag manually to your theme's header.php file inside the head section. (3) Use a custom HTML block or code injection tool in your page editor. (4) Use a dedicated structured data plugin like Schema Pro. For manual implementation, paste the generated script tag just before the closing head tag.
