Free Schema Markup Generator (JSON-LD)
Generate valid JSON-LD schema markup for FAQ, HowTo, Article, Product, Organization, and BreadcrumbList. Boost rich-result eligibility in Google Search and citation rate in AI Overviews. Free, browser-only, no signup.
Schema Type
For pages with a list of question + answer pairs (FAQ accordions). Add 3-15 items.
Fill in the required fields above to generate JSON-LD.Quick Answer
A schema markup generator produces valid JSON-LD code that you embed in your site's <head> to tell search engines and AI assistants what your page is about. The U2L generator builds Schema.org-compliant FAQ, HowTo, Article, Product, Organization, and BreadcrumbList markup from a simple form. Output validates green in Google's Rich Results Test.
Quick Facts
- Schema markup is the foundation of rich SERP results: FAQ accordions, HowTo step previews, star ratings, product carousels, breadcrumbs in URL displays.
- JSON-LD is Google's recommended format (vs Microdata or RDFa). Goes in a <script type='application/ld+json'> tag in the page <head>.
- All major AI search engines (ChatGPT, Perplexity, Claude, Gemini, Bing Chat) parse Schema.org markup when synthesizing answers. Pages with structured data get cited 3-5x more often.
- Schema.org defines 800+ types. The 'big six' that drive most SEO/GEO value: FAQPage, HowTo, Article, Product, Organization, BreadcrumbList.
- Google Rich Results Test (search.google.com/test/rich-results) is the official validator. Schema.org Validator (validator.schema.org) catches more edge cases.
- Markup must reflect actual page content. Inventing FAQs that aren't on the page violates Google's structured data guidelines and can earn manual penalties.
- JSON-LD adds zero visible content; everything is in the script tag. No CSS, no design changes, just metadata for search engines and AI agents.
How to generate schema markup
Three steps. Pick the type, fill the form, paste the output.
- 1
Pick a schema type
FAQ for Q&A pages, HowTo for tutorials, Article for blog posts, Product for e-commerce listings, Organization for your business profile, BreadcrumbList for navigation. Choose the one that matches your page's primary content.
- 2
Fill in the fields
Each schema type has its own required and optional fields. The tool guides you through what's needed: FAQs need question/answer pairs; HowTo needs steps with names and text; Article needs headline, author, publish date, image. Add as many entries as your page has.
- 3
Copy the JSON-LD and paste into your page
Tap Copy. Paste into your page's <head>, wrapped in a <script type='application/ld+json'>...</script> tag. Validate with Google's Rich Results Test before publishing. Re-validate after major page changes to keep schema in sync with content.
What is a Schema Markup Generator?
Schema Markup Generator is a tool that produces valid JSON-LD code for Schema.org structured data. Pick a schema type (FAQ, HowTo, Article, Product, Organization, BreadcrumbList), fill in the fields, and copy the generated JSON-LD into your page's <head>. The output validates against Google's Rich Results Test and is read by every major search engine and AI assistant for rich-result rendering and answer synthesis.
Schema.org is a vocabulary co-created by Google, Bing, Yahoo, and Yandex in 2011 to standardize how web pages describe their content to search engines. The vocabulary defines hundreds of types (Article, Product, Recipe, Event, Person, Organization, FAQPage, HowTo, etc.) and properties for each (headline, author, datePublished, price, image, etc.). Pages that mark up their content with Schema.org tags become eligible for rich results: FAQ accordions in Google search, HowTo step previews, recipe cards with cooking time, product carousels with star ratings.
JSON-LD is the format Google recommends. It's a JSON-formatted structured data block that lives in a <script type='application/ld+json'> tag in the page's <head>, separate from the visible HTML. Google switched its recommendation from Microdata (inline attribute markup) to JSON-LD around 2015 because JSON-LD is easier to maintain (one block, not scattered attributes) and easier for crawlers to parse reliably.
Beyond traditional SEO, structured data has become essential for AI-first search. ChatGPT, Perplexity, Claude, Gemini, and Bing Chat all parse Schema.org markup when generating answers. Pages with comprehensive structured data get cited materially more often in AI-generated responses, because the markup tells the AI exactly what type of content the page contains and which fields are which. This is the 'GEO' (Generative Engine Optimization) play: structured data is the bridge from your content to AI assistant citations.
How does a Schema Markup Generator work?
When you fill the form and click Copy, the tool builds a JSON object conforming to the Schema.org spec for the selected type. The @context field is set to https://schema.org. The @type field is set to the chosen schema (FAQPage, HowTo, etc.). Required and optional fields are populated based on your input. The output is JSON, ready to wrap in a <script> tag.
Each schema type has different required and optional fields. FAQPage requires mainEntity (an array of Question objects, each with a name and an acceptedAnswer with a text). HowTo requires step (an array of HowToStep objects with name and text). Article requires headline, datePublished, and author. Product requires name and offers (with price and priceCurrency). Organization requires name; url and logo are recommended. BreadcrumbList requires itemListElement (array of ListItem with position, name, and item URL).
The tool validates fields client-side as you type. Required fields are highlighted; missing fields generate a warning before output. The generated JSON validates against Google's Rich Results Test and the official Schema.org validator. Edge cases (special characters in names, datetime format normalization, URL absolutization) are handled automatically.
You paste the JSON-LD into the <head> of your page, wrapped in <script type='application/ld+json'>...</script>. The script tag has type='application/ld+json' (not text/javascript) so the browser doesn't try to execute it. Search engines and AI crawlers parse the JSON content directly. The page's visible HTML is unchanged; structured data lives only in the script tag.
Use Cases
How marketers, businesses, and developers use schema markup generator.
FAQ pages on product or service sites
Add FAQPage schema to your pricing, support, and product pages. Google often renders the FAQ as an accordion directly in search results, increasing CTR and reducing the 'I have a question' support load.
HowTo articles and tutorials
Recipe sites, DIY blogs, and SaaS knowledge bases all benefit from HowTo schema. Google can render step-by-step previews directly in search; AI assistants cite HowTo content more often when they recognize it as procedural.
Blog posts and editorial content
Article schema with headline, author, datePublished, and image makes blog posts eligible for the 'Top Stories' carousel and AMP-style article previews. Critical for news sites and content brands.
E-commerce product pages
Product schema with offers, price, currency, availability, and review aggregation drives star-rating display in search and 'in stock' badges. Often a 30-50% CTR lift on product searches.
Local business and service pages
LocalBusiness or Organization schema with address, telephone, openingHours, and geo coordinates feeds Google's local pack and Maps results. Combined with reviews, drives the visible business profile.
Documentation and developer tools
API docs, SDK guides, and tutorial pages benefit from HowTo + TechArticle schema. Helps GitHub Copilot, Cursor, and ChatGPT cite your docs accurately when answering developer questions.
Recipe and cooking sites
Recipe schema is one of the original rich-result formats. Cooking time, ingredient list, nutrition info, and image populate Google's recipe carousel - a major traffic source for food publishers.
Event and ticketing pages
Event schema with startDate, location, and offers drives event-specific rich results: date pickers, ticket-purchase buttons, and 'add to calendar' integrations across Google products.
Job postings
JobPosting schema is Google's required format for the Google Jobs vertical. Without it, your job posts won't appear in 'jobs near me' searches.
Course and education content
Course schema for online courses, Lesson schema for individual lessons. Drives Google's education carousel and helps AI assistants accurately summarize curricula when users ask.

Schema Markup Generator vs Merkle Schema Markup Generator
Merkle's free schema generator is the best-known free option, popular in SEO circles. Covers most common types and produces valid output. UI is functional but dated; only six schema types supported.
U2L's generator covers the same big six (FAQ, HowTo, Article, Product, Organization, BreadcrumbList) with a cleaner UI, runs entirely in your browser (no server upload of your data), and is part of a wider link-management toolkit (you can wrap any URLs in your schema in u2l.ai short links for click tracking).
Schema Markup Generator vs Yoast SEO (WordPress plugin)
Yoast auto-generates schema for WordPress sites based on your content. Free for basic setup; Yoast Premium adds advanced types and better validation. The trade-off: only useful inside WordPress.
U2L's generator works for any site (Astro, Next.js, custom HTML, Shopify, Webflow, Squarespace). For WordPress sites, Yoast is fine. For everything else, a standalone generator like U2L's gives you the JSON-LD output you can paste into any framework.
Best Practices
Match markup to actual page content
The schema must reflect what's visible on the page. Inventing FAQs that aren't shown to users, fake reviews, or non-existent products violates Google's structured data guidelines and can earn manual penalties.
Validate before publishing
Always run the generated JSON-LD through Google's Rich Results Test (search.google.com/test/rich-results) before deploying. Catches typos, missing required fields, and format issues that would prevent rich result eligibility.
Place JSON-LD in <head>, not <body>
Convention is to put structured data in the <head>. Some platforms (and crawlers) handle <body> placement, but <head> is universally supported and faster to parse.
Use one JSON-LD block per logical entity
Don't combine FAQ and Article into one block. Two separate <script> tags in the head, one per type, is cleaner and easier to debug. Crawlers handle multiple blocks fine.
Update schema when content changes
If you update an FAQ answer or add a new product variant, update the JSON-LD too. Stale schema is worse than no schema; Google penalizes mismatches between markup and visible content.
Use absolute URLs for image, sameAs, and item fields
https://yoursite.com/og.png, not /og.png. Relative URLs work in some platforms and break in others. Always use absolute URLs in JSON-LD.
Set datePublished and dateModified for Article
Both fields signal recency to Google and AI engines. Article without dates ranks lower for time-sensitive queries. Update dateModified whenever you make a substantive content change.
Use FAQPage schema for FAQ accordions, not for general Q&A
FAQPage is for FAQs visible on the page (a list of questions and answers about a single topic). Don't use it for general support docs, knowledge bases, or comment sections - those need different schema types (Article, HowTo, etc.).
Cite the schema type that best matches the page
Multiple types could fit a page. Pick the most specific one. A blog post is Article; a how-to article is HowTo; a recipe is Recipe. Specific schema gets richer results than generic ones.
Common Mistakes to Avoid
Marking up content not visible to users
Adding 50 FAQ entries in JSON-LD when the page only shows 5 is a violation. Google's policy requires markup to match visible content. Penalty: manual action and possible structured-data demotion.
Inventing reviews or ratings
Adding aggregateRating or Review schema without underlying real reviews is a high-risk policy violation. Penalty: manual action, demotion, and possible deindexing.
Using the wrong schema type
A blog post with HowTo schema doesn't get HowTo rich results because Google checks that the markup matches the content. Pick the type that genuinely fits; don't shoehorn for richer results.
Forgetting required fields
Each type has required fields (Article needs headline, datePublished, author). Missing required fields makes the schema invalid; Google's Rich Results Test will flag it.
Using unsupported field values
datePublished must be ISO 8601 (e.g. 2026-05-01); 'May 1, 2026' is invalid. Image URLs must be absolute. Currency codes must be ISO 4217 (USD, INR, EUR). Validate before publishing.
Putting schema in <body> instead of <head>
Works in some crawlers but breaks in others. Always put JSON-LD in <head>. Most CMS templates have a 'add to head' option.
Stale schema after content changes
Updating an FAQ answer in the visible HTML but not in the JSON-LD creates a mismatch. Schedule schema audits with major content changes.
