Schema Markup Generator FAQ
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.
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.
Two rules keep structured data trustworthy. It must describe the page it is on, not some other page. And it must match what visitors can see: marking up a price, rating or answer that is not visible is treated as deception. Keep the markup in step with the page when prices, dates or details change, and test it after every template change.
