What Is the Schema Markup Generator and How Does It Work?

Generate JSON-LD schema markup for articles, products, local businesses, organizations, people, events, FAQ pages, breadcrumbs and websites, with checks for missing properties.

Telling machines what a page means

People read a page and understand at once that it shows a product with a price, or an event on a date. Software has to guess from the text.

Structured data removes the guesswork: it states the facts in a fixed vocabulary, so that search engines, voice assistants and other tools can use them with confidence.

The vocabulary is schema.org, maintained jointly by the major search engines. It defines types, such as Article, Product and Event, and properties for each, such as headline, price and startDate.

JSON-LD is a way of writing those statements as a small block of JSON placed in the page. Unlike older formats it does not have to be woven into the visible HTML.

Search engines use the data in two ways. It helps them understand what a page is about, and for certain types it makes the page eligible for richer search results: a price and availability under a product, a date under an event, a breadcrumb trail instead of a raw URL.

Each feature has required properties, which is why this generator points out what is missing.

How to Use the Schema Markup Generator: Step-by-Step Guide

Open the Schema Markup Generator and follow these steps:

  1. Step 1: Choose the schema type that matches the page.
  2. Step 2: Fill in the fields; optional ones can stay empty.
  3. Step 3: Check the notes under the result for missing or malformed values.
  4. Step 4: Copy the block into the page’s HTML and test it with a validator.

That is all – no installation, no account and no watermark.

Frequently Asked Questions About the Schema Markup Generator

What is schema markup?

It is a standard vocabulary (schema.org) for describing the content of a page in a form machines can read: this is a product, its price is this, it is in stock. Search engines use it to understand pages and sometimes to show enhanced results.

Why JSON-LD?

It is the format Google recommends. The data sits in one script block, separate from the visible HTML, which makes it easy to add and maintain.

Where do I put the code?

Anywhere in the HTML of the page it describes, usually in the head. Many content systems and plugins offer a field for custom structured data.

Does schema markup guarantee rich results?

No. It makes a page eligible.

Search engines decide whether to show an enhanced result, and they require the marked-up information to be visible on the page and accurate.

Can I mark up ratings?

Only genuine ratings from customers that are shown on the page. Invented or self-awarded ratings violate search engine guidelines and can lead to a manual action.

How do I test the result?

Use Google’s Rich Results Test for features Google supports, and the Schema Markup Validator at validator.schema.org for general correctness.
