Schema Markup Generator
Generate valid JSON-LD structured data for your pages in seconds. Fill in a
simple form and get clean, Google-ready markup for Organization, Article, FAQ,
Review and LocalBusiness schema — ready to paste straight into your page's
<head>.
Runs entirely in your browser. Your data never leaves your device.
Organization
Describes a company or brand. Add this once, sitewide (often on the homepage), inside <head>. Powers the brand knowledge panel and logo in search.
Article
For blog posts and news articles. Place in <head> of the article page. Required by Google: headline, image, datePublished.
FAQ
A list of questions and answers. Google retired FAQ rich results in May 2026, but FAQ schema still helps AI assistants and search engines understand your Q&A. Place it in <head> of the page where the same Q&As are visible to users, and add at least one question with an answer.
Review
A single review of an item (product, business, book, etc.). Required by Google: the item being reviewed, a rating, and the author. Review stars show for products and other eligible items, not for a business reviewing itself.
LocalBusiness
For a physical business location. Place in <head> of your contact or location page. Required by Google: name and address.
JSON-LD output
Ready
Paste the highlighted <script> block into your page's <head>.
Multiple selected types are combined into a single @graph array automatically.
About this schema markup generator
Structured data is how you tell search engines and AI assistants what your content actually means: not just the words on the page, but the entities behind them, like your business, your articles, your reviews and your frequently asked questions. Tools like ChatGPT, Claude and Perplexity read this JSON-LD to understand and cite your pages accurately, and Google can use it to show richer search results.
This free tool builds that JSON-LD for you. There is no signup and nothing to install. Everything runs locally in your browser, so the information you type never touches a server. Pick a schema type, fill in the form, and copy the generated code into your page.
Common schema types, briefly
Organization describes your brand and feeds the knowledge panel. Article marks up blog posts and news. FAQ gives AI assistants and search engines clean, machine-readable Q&A about your page. Review adds star ratings to eligible results. LocalBusiness helps a physical location appear with its address, hours and map.
Frequently asked questions
What is JSON-LD structured data?
JSON-LD (JavaScript Object Notation for Linked Data) is Google's recommended format for structured data. It is a small block of code you add to a page that describes its content to search engines, helping them understand entities like your business, articles, reviews and FAQs.
Where do I place the schema markup code?
Paste the generated <script type="application/ld+json"> block inside the <head> of your page. It also works in the <body>. A single block can describe multiple entities at once using an @graph array, which is exactly what this tool produces when you select more than one type.
Why does structured data matter for SEO?
Structured data gives AI assistants like ChatGPT, Claude and Perplexity machine-readable facts about your page, so they can understand and cite it accurately. In Google Search it also makes pages eligible for rich results like review stars, article cards and business knowledge panels. It does not guarantee those results, but it is a prerequisite for them.
Is this generator really free and private?
Yes. It is completely free with no signup. The tool is a single HTML file that runs entirely in your browser, so the data you enter never leaves your device. Your last entries are remembered locally so you can pick up where you left off.
How do I validate my markup?
Use the “Test in Google Rich Results” button. It copies your generated code and opens Google's Rich Results Test, where you can paste the snippet and confirm it is valid and eligible for rich results.
