Schema Generator

About this Schema Generator

Generate valid JSON-LD structured data for Organization, LocalBusiness, Article, FAQ, Product, WebSite and HowTo. It is one of the SEO and Webmaster on ToolUstad, and like every tool here it runs entirely in your browser: nothing you type, paste or open is uploaded to a server, and there is no sign-up or usage limit.

What is schema markup?

Schema markup is structured data written in the Schema.org vocabulary that labels what things on a page are: this is a business, this is a product with a price, these are questions and answers. Google uses it to power rich results such as star ratings, FAQ accordions, prices and breadcrumbs in search results. JSON-LD, the format this generator writes, is the format Google recommends, because it sits in one script block and does not touch your visible HTML.

Schema types this generator builds

When and why to add structured data

• E-commerce: Product schema with offers and review data is how prices and stars reach the results.
• Local businesses: LocalBusiness schema confirms your address, opening hours and phone to Google.
• Content sites: Article and FAQPage schema clarify authorship, dates and answers.
• Any site: BreadcrumbList makes your result show a clean path instead of a long URL.

Best practices

• Only mark up content that is visible to visitors on the same page: hidden data risks a manual action.
• Validate the output in Google's Rich Results Test before and after publishing.
• Keep data accurate: update prices, ratings and hours in the schema when they change on the page.
• Use the most specific type available, for example Dentist instead of generic LocalBusiness.

Common mistakes to avoid

• Adding FAQ schema to pages with no visible questions and answers.
• Marking up reviews you wrote yourself or copied from another site.
• Invalid JSON from a missing comma, which makes Google ignore the whole block.
• Marking every page as an Article regardless of what the page actually is.

Who is the schema generator for?

SEO specialists, developers, e-commerce managers and local business owners who want rich results without memorising the Schema.org specification. Hand writing JSON-LD is slow and one syntax slip invalidates it, while the generator asks for the fields in plain language and outputs valid, ready to paste code. Agencies can use it to produce client-ready markup without opening an editor or checking the Schema.org docs by hand.

How to test and maintain your markup

Adding the script is step one; keeping the rich result is the ongoing job. Run every new template through Google's Rich Results Test, then check the enhancement reports in Search Console a week after launch, because Google reports schema errors per page type there at scale. The most common production failure is drift: the page price changes but the Product schema does not, or opening hours change in one place only. Treat the JSON-LD as part of the content, reviewed whenever the visible page is edited, and your markup will keep passing long after the launch day screenshot.
