Last updated Jan 19, 2026 by [Harlan Wilton](https://github.com/harlan-zw) in [docs: sync](https://github.com/unjs/unhead/commit/d2f86454774aa60706628b46a850653e1e4d56d9).

- [How do I add a custom Schema.org node?](#how-do-i-add-a-custom-schemaorg-node)
- [Which nodes are officially supported?](#which-nodes-are-officially-supported)

**Quick Answer:** Schema.org nodes are created with `define*` functions like `defineArticle()`, `defineProduct()`, etc. Each function validates input and outputs valid JSON-LD.

Official nodes are ones that have a direct impact on Google Rich Results.

## [How do I add a custom Schema.org node?](#how-do-i-add-a-custom-schemaorg-node)

If you need a node that isn't officially supported, provide it as a plain object following the [Schema.org specification](https://schema.org/docs/full.html).

For TypeScript support, use [schema-dts](https://github.com/google/schema-dts).

Untyped

schema-dts

```
import { useSchemaOrg } from '@unhead/schema-org/typescript'

useSchemaOrg([
  {
    '@type': 'DefinedTerm',
    'name': 'Nuxt Schema.org',
    'description': 'Nuxt Schema.org is a Nuxt module for adding Schema.org to your Nuxt app.',
    'inDefinedTermSet': {
      '@type': 'DefinedTermSet',
      'name': 'Nuxt Modules',
    },
  }
])
```

```
import type { DefinedTerm } from 'schema-dts'
import { useSchemaOrg } from '@unhead/schema-org/typescript'

const NuxtSchemaOrgDefinedTerm: DefinedTerm = {
  '@type': 'DefinedTerm',
  'name': 'Nuxt Schema.org',
  'description': 'Nuxt Schema.org is a Nuxt module for adding Schema.org to your Nuxt app.',
  'inDefinedTermSet': {
    '@type': 'DefinedTermSet',
    'name': 'Nuxt Modules',
  },
}

useSchemaOrg([NuxtSchemaOrgDefinedTerm])
```

## [Which nodes are officially supported?](#which-nodes-are-officially-supported)

Officially supported nodes are those that enable Google Rich Results. Each has a dedicated `define*` function with validation and auto-completion.
