Documentation
Schema Markup Generator documentation
Generate copy-ready JSON-LD for common page, article, and product schema types.
Overview
Use it when the format needs to change, not the meaning
Use Schema Markup Generator when you want a predictable JSON-LD starting point before validation.
Content QA
Check the fields you need for articles and product pages.
Validator handoff
Send the generated output straight into the validator for a final pass.
Supported inputs
Bring clean source text and keep the direction straight
- Accepts WebPage, Article, and Product schema types.
- Common fields cover titles, descriptions, URLs, images, authors, publishers, brands, and offers.
- Copy the JSON-LD output and review it in the schema validator when you need an extra check.
Walk through it
Follow the same sequence you see in the tool
Workflow
Generate schema markup
Use this flow when you need a clean JSON-LD starter block.
- Pick the schema type that matches the page or product.
- Fill in the shared fields and any type-specific details.
- Copy the JSON-LD or script wrapper into the destination page.
Workflow
Validate the result
Use this flow when you want a second pass before shipping markup.
- Generate the JSON-LD from the tool.
- Open the structured data validator with the copied output.
- Fix any schema warnings before you publish the page.
What you get
Check the result before you copy it into the next step
Normalized JSON-LD
A clean, pretty-printed JSON-LD document appears for copying.
Script wrapper
The output is wrapped in an embeddable application/ld+json script tag.
Type-specific hints
Advisory checks point out missing rich data for the selected schema type.
Avoid these mistakes
Small input problems create the biggest conversion errors
Using the wrong schema type
Match the selected type to the page content before copying the result.
Skipping offer data
Add price and availability fields when the page is really a product.
Not validating the copy
Run the structured data validator when the markup needs a final review.
Glossary
Decode the terms before you act on them
This section translates the most technical labels on the page into plain language so you can interpret the output without opening another tab.
JSON-LD
JSON-LD is the structured-data format this generator produces so the markup can be embedded on a page in a predictable way.
WebPage
WebPage is a general schema type for describing a normal page when a more specific content type does not fit.
Article
Article is a schema type for editorial content such as posts, guides, and news items.
Product
Product is a schema type for a purchasable item and usually works best when price, availability, and brand details are also present.
Offer
An offer is the structured-data block that describes how a product is sold, including fields like price, currency, and availability.
