Free Schema Markup Generator
This free schema markup generator builds valid JSON-LD structured data — FAQ, HowTo, Local Business, or Article — ready to paste straight into your site's <head>. No signup, nothing leaves your browser.
<!-- Your schema markup will appear here -->
Paste this inside your page's <head>, or anywhere in <body> — search engines read it either way.
What Is Schema Markup?
Schema markup (also called structured data) is a standardized code format — usually JSON-LD — that tells search engines exactly what your content means, not just what it says. A page of plain text says "we're open 9 to 5"; schema markup says this is a LocalBusiness, and its openingHours is 09:00-17:00 in a format Google can parse with certainty.
Google, Bing, and increasingly AI answer engines use this data to build rich results: star ratings under a search listing, FAQ dropdowns directly in the SERP, step-by-step How-To carousels, and business info panels — all without a person having to read your page first.
Which Schema Type Should You Use?
| Type | Best for | Possible rich result |
|---|---|---|
| FAQPage | Any page with a genuine Q&A section | Expandable FAQ dropdown in search results |
| HowTo | Step-by-step instructions | Numbered step carousel |
| LocalBusiness | A physical business location | Knowledge panel details, map integration |
| Article | Blog posts and news articles | Author/date display, Top Stories eligibility |
Common Mistakes to Avoid
- Marking up content that isn't visible on the page — Google's guidelines require structured data to reflect what a visitor can actually see and read
- Using FAQPage markup on marketing copy dressed up as questions — it should be genuine, distinct questions with real answers, not disguised ad copy
- Forgetting to update dates and prices — stale structured data (like an old price) can get a listing flagged or ignored
- Stacking multiple conflicting schema types on one page — only mark up what the page is actually about
How to Add This to Your Site
- Choose a schema type above and fill in the real details for your page
- Copy the generated code or download it as an HTML snippet
- Paste it into your page's
<head>(or anywhere in<body>) - Test it with Google's Rich Results Test before publishing
- Update the markup whenever the underlying page content changes
Free Schema Markup Generator FAQs
Do I need to know how to code to use this?
No. Fill in the plain-language form fields and the tool writes the correct JSON-LD syntax for you. Pasting the result onto your site is the only technical step, and it's the same as adding any other snippet of HTML.
Will adding schema markup guarantee rich results in Google?
No. Structured data makes your page eligible for rich results — it doesn't guarantee them. Google still decides whether and how to display them based on overall page quality and relevance.
Does this tool store or send my data anywhere?
No. Everything is generated in your browser with JavaScript — nothing is uploaded, logged, or stored on any server, including ours.
Can I add more than one schema type to the same page?
Yes, technically — a page can carry multiple <script type="application/ld+json"> blocks. Just make sure each one accurately describes real, visible content on that specific page.
Where exactly should I paste the generated code?
Anywhere in your page's HTML — the <head> is the most common convention, but search engines read JSON-LD from anywhere in the document.
How do I check my schema markup is valid?
Paste your page URL or the code directly into Google's Rich Results Test — it flags syntax errors and shows which rich results your page qualifies for.
