Schema Markup Generator

The Schema Markup Generator creates JSON-LD structured data for any schema.org type, ready to paste into your HTML. Structured data helps Google understand your content and enables rich results in search: recipe cards with cooking times and ratings, article cards with publication dates and images, product snippets with prices and availability, FAQ accordions directly in search results, event cards with dates and locations. Without structured data, your pages show as plain blue links; with it, they stand out.

Pick a schema type (Article, Product, Recipe, FAQ, Event, Organization, LocalBusiness, BreadcrumbList, and more), fill in the fields via the form, and the tool outputs valid JSON-LD you drop into a <script type=\"application/ld+json\"> tag. Validation ensures required fields are present and data types match schema.org specs. Preview shows how the rich result might appear in Google. All generation runs client-side so proprietary business data stays in your browser.

Schema.org is a collaborative project (Google, Microsoft, Yahoo, Yandex) defining vocabulary for structured data on the web. Over 800 types covering articles, events, products, places, people, and more.

JSON-LD is the preferred format. Recommended by Google over microdata or RDFa. Looks like:

<script type=\"application/ld+json\">
{
\"@context\": \"https://schema.org\",
\"@type\": \"Article\",
\"headline\": \"Title\",
\"author\": { \"@type\": \"Person\", \"name\": \"Ana Kowalski\" },
\"datePublished\": \"2024-05-05T12:00:00Z\"
}
</script>

@context: always https://schema.org
@type: the schema type (Article, Product, Recipe, etc.)
Remaining properties: fields defined by that type

Common types and their key fields:

Article: headline, image, datePublished, dateModified, author, publisher.

Product: name, image, description, brand, offers (with price, priceCurrency, availability), aggregateRating.

Recipe: name, image, description, author, cookTime (ISO 8601 duration), recipeIngredient, recipeInstructions, nutrition.

FAQPage: mainEntity array of Question objects, each with name (question) and acceptedAnswer.

Event: name, startDate, endDate, location (Place), offers.

LocalBusiness: name, address (PostalAddress), telephone, openingHoursSpecification, geo (GeoCoordinates).

BreadcrumbList: itemListElement array of ListItem objects with position, name, item (URL).

Organization/Person: similar fields for brand/individual identification.

Rich results requirements vary by type. Recipes need specific fields for the recipe card; without them, you get no rich result even with valid JSON-LD. Google\u2019s Rich Results Test validates against these specific requirements.

ISO 8601 dates and durations: structured data uses ISO 8601. Duration format is PT1H30M (1 hour 30 minutes), PT20M (20 minutes), etc.

Nested types: many fields expect other schema types. A Product\u2019s offers field is an Offer type, which has price, priceCurrency, availability, etc.

Validation: JSON syntax + schema.org type compliance + Google rich result requirements. This tool handles the first two; Google\u2019s Rich Results Test covers the third.

Compared to writing JSON-LD by hand, this tool structures the input via forms and validates as you go. Hand-writing JSON-LD works but is error-prone for complex schemas.

Compared to Google\u2019s Structured Data Markup Helper (discontinued), this tool is a modern replacement with more schema types and JSON-LD output.

Compared to specialized schema plugins (Yoast, Rank Math), this tool is framework-agnostic. Plugins integrate with WordPress; this tool works for any stack.
