Schema Markup Generator

Generate valid JSON-LD structured data for six common schema types.

What this tool does

The Schema Markup Generator creates JSON-LD structured data for six schema types: Article, FAQ, HowTo, Person, Organization, and LocalBusiness. You fill in the relevant fields, and it produces validated JSON-LD you can copy into your page.

Structured data helps search engines understand your content and can unlock rich results — FAQ accordions, how-to carousels, and knowledge panels. Hand-writing JSON-LD is error-prone; this tool only emits the supported fields for each type.

It includes basic validation: required fields are checked, dates are validated, and invalid input is flagged before you copy anything. It never invents fields or values.

How to use it

  1. Pick a schema type from the selector.
  2. Fill in the fields for that type.
  3. Review the generated JSON-LD preview and validation messages.
  4. Copy the JSON-LD and paste it into the <head> of your page.

How it works

  • Each schema type maps to a fixed set of supported properties. Article includes headline, author, publisher, datePublished, and url; FAQ includes a mainEntity array of questions and answers; HowTo includes an ordered step list.
  • Fields left blank are omitted from the output rather than emitted as empty values.
  • Validation flags missing required fields, invalid URLs, and dates that do not use YYYY-MM-DD.

Example

A FAQ with two question/answer pairs produces a FAQPage JSON-LD object with a mainEntity array of two Question objects — ready for a rich result.

Common questions

Will this get me rich results?
Valid markup is necessary but not sufficient. Google decides whether to show rich results based on quality and guidelines. Correct JSON-LD is the first step.
Where should JSON-LD go?
Typically in the <head> of the page as a <script type="application/ld+json"> block, though body placement also works.
Does it support every schema type?
No. It supports six common types and only their documented fields. Unsupported fields are deliberately not generated.
