🏷️ Schema Markup Generator (JSON-LD)
By ToolNimba SEO Team · Updated 2026-06-19
Paste this block into the <head> (or anywhere in the body) of the page it describes.
This schema markup generator builds valid JSON-LD structured data for the five types most pages need: FAQPage, Article, Product, LocalBusiness, and Organization. Pick a type, fill in the relevant fields, and copy a ready-to-paste <script type="application/ld+json"> block. Structured data helps search engines understand your page and can unlock rich results such as FAQ accordions, star ratings, and business info panels. Everything runs in your browser, so nothing you type is ever sent to a server.
What is the Schema Markup Generator?
Schema markup is a shared vocabulary, defined at schema.org, that lets you label the meaning of content on a page. Instead of leaving a search engine to guess that "$79.99" is a price or that a block of text is an author bio, you state it explicitly. Google, Bing, and others read this machine-readable layer to populate rich results: the expandable questions under a result, the price and availability on a product, the rating stars, or the knowledge panel for a brand. The markup does not change what a human visitor sees, it sits quietly in the page source.
There are three syntaxes for adding schema (JSON-LD, Microdata, and RDFa), but Google explicitly recommends JSON-LD, and it is what this tool produces. JSON-LD keeps all the structured data in a single script block rather than scattering attributes through your HTML, so it is easy to add, edit, and remove without touching your visible markup. You drop the generated <script type="application/ld+json"> block into the <head> or anywhere in the <body>, and it applies to that page.
The golden rule is that structured data must describe content that is genuinely present and visible on the page. Marking up FAQs that do not appear to users, inflating a product with a fake review rating, or describing a business that the page is not actually about all violate Google guidelines and can trigger a manual action. Used honestly, schema is one of the lowest-risk, highest-leverage technical SEO wins available, and this generator removes the fiddly job of getting the JSON syntax exactly right.
When to use it
- Adding FAQPage markup to a help or product page so the questions can show as an expandable rich result.
- Marking up a blog post or news story with Article schema (headline, author, dates) for better understanding and eligibility for rich features.
- Giving an e-commerce product page Product and Offer markup with price, currency, and availability.
- Helping a local shop, restaurant, or office appear correctly with name, address, phone, and hours via LocalBusiness schema.
- Defining a brand once with Organization schema (logo, social profiles) to support the knowledge panel and sameAs links.
How to use the Schema Markup Generator
- Choose the schema type that matches the page you are marking up (FAQPage, Article, Product, LocalBusiness, or Organization).
- Fill in the fields shown for that type. Optional fields can be left blank and are simply dropped from the output.
- For FAQPage, add one row per question and answer, and remove the seeded examples.
- Read the generated JSON-LD in the output box, which updates as you type.
- Click Copy, then paste the whole <script type="application/ld+json"> block into your page and validate it with Google’s Rich Results Test.
Formula & method
Worked examples
You want FAQPage markup for a support page with two questions.
- Select FAQPage as the type.
- In the first row, enter the question "Do you offer refunds?" and the answer "Yes, within 30 days of purchase."
- Add a second row for "How long is shipping?" with its answer.
- The tool wraps each pair as a Question with an acceptedAnswer of type Answer inside a mainEntity array.
Result: A FAQPage object whose mainEntity is an array of two Question objects, each with an acceptedAnswer, ready to paste into the page that shows those FAQs.
You are marking up a product priced at 79.99 USD that is in stock.
- Select Product and enter the name "Wireless Headphones".
- Enter price 79.99 and currency USD, and leave availability on In stock.
- The tool builds an offers object of @type Offer with price "79.99", priceCurrency "USD", and availability "https://schema.org/InStock".
Result: A Product object with a nested Offer, where availability uses the full schema.org URL that Google expects.
Schema types in this tool and the rich results they can support
| Schema type | Best for | Possible rich result |
|---|---|---|
| FAQPage | Help, support, product FAQ pages | Expandable questions in search |
| Article | Blog posts, news, guides | Article rich result, Top stories eligibility |
| Product | E-commerce product pages | Price, availability, merchant listings |
| LocalBusiness | Shops, restaurants, offices | Business info and knowledge panel |
| Organization | Company / brand home pages | Knowledge panel, logo, sameAs links |
Common Offer availability values (schema.org URLs)
| Status | Value emitted |
|---|---|
| In stock | https://schema.org/InStock |
| Out of stock | https://schema.org/OutOfStock |
| Pre-order | https://schema.org/PreOrder |
| Back-order | https://schema.org/BackOrder |
Common mistakes to avoid
- Marking up content that is not on the page. Structured data must describe what users actually see. FAQ schema for questions that are not visible, or a rating with no reviews, violates Google’s guidelines and can lead to a manual action that removes all your rich results.
- Using the wrong availability or currency format. Offer availability must be a full schema.org URL such as https://schema.org/InStock, and priceCurrency must be a 3-letter ISO code like USD or EUR. This tool fills both in the correct format for you.
- Forgetting to validate after pasting. Always run the page through Google’s Rich Results Test or the Schema Markup Validator after adding the block. A typo in the surrounding HTML, or a missing required field, can stop the markup from being parsed.
- Adding the same type twice with conflicting data. Two competing Organization or Product blocks on one page can confuse parsers. Keep one authoritative block per type, and make sure its values match the visible page exactly.
- Pasting the JSON without the script wrapper. JSON-LD must live inside a <script type="application/ld+json"> tag. The Copy button includes the wrapper, so paste the entire block, not just the curly-brace object.

Frequently asked questions
What is a schema markup generator?
It is a tool that builds valid JSON-LD structured data for you from a few form fields. You pick a schema type such as FAQPage or Product, fill in the details, and the generator outputs a ready-to-paste <script type="application/ld+json"> block, so you do not have to write the JSON by hand or risk a syntax error.
Where do I put the generated JSON-LD code?
Paste the entire <script type="application/ld+json"> block into the HTML of the page it describes. It can go in the <head> or anywhere in the <body>; both work. Add it only to the specific page whose content it represents, not site-wide, unless the markup (like Organization) genuinely applies to every page.
Does adding schema markup guarantee rich results in Google?
No. Valid structured data makes a page eligible for rich results, but Google decides whether to show them based on quality, relevance, and its own guidelines. Schema improves your chances and helps search engines understand your content, but it is not a switch that forces an enhanced listing.
Is JSON-LD better than Microdata or RDFa?
For most sites, yes. Google explicitly recommends JSON-LD because it keeps all the structured data in one script block instead of weaving attributes through your visible HTML. That makes it far easier to add, update, and remove without breaking your page layout, which is why this tool generates JSON-LD.
Is this tool private, and does my data get uploaded?
Everything runs entirely in your browser using plain JavaScript. Nothing you type into the fields is sent to any server, logged, or stored. You can disconnect from the internet and the generator still works, which makes it safe to use with business addresses, phone numbers, and other details.
How do I check that my markup is correct?
Copy the generated block, paste it into Google’s Rich Results Test or the Schema Markup Validator at validator.schema.org, and run the check. Those tools report missing required fields and warnings, so validate every block before and after it goes live to confirm it is parsed correctly.
