Launch AI GeneratorWhat is PropertyValueSpecification Schema?
A Property value specification.
Google uses PropertyValueSpecification structured data to understand the content and context of your pages. When correctly implemented, this schema can unlock rich results in Google Search — enhancing your listing with additional information that dramatically improves visibility and click-through rates.
Why Add PropertyValueSpecification Structured Data?
Appear in Rich Results
Structured data helps Google show enhanced results for your pages in search — including stars, prices, FAQs, and more.
Boost Click-Through Rate
Rich snippets can increase CTR by up to 30% compared to plain search results — more clicks with the same ranking.
Feed AI Search Engines
AI answer engines like Perplexity and Google SGE use structured data to verify and cite facts from your content.

Properties You Can Include
PropertyValueSpecification schema supports the following schema.org properties. Required fields are the minimum Google needs to consider your markup valid; recommended fields unlock richer search result appearances.
| Property | Description | Expected Type | Status |
|---|---|---|---|
| additionalType | An additional type for the item, typically used for adding more specific types from external vocabularies in microdata syntax. This is a relationship between something and a class that the thing is in. Typically the value is a URI-identified RDF class, and in this case corresponds to the use of rdf:type in RDF. Text values can be used sparingly, for cases where useful information can be added without their being an appropriate schema to reference. In the case of text values, the class label should follow the schema.org style guide. | Text, URL | Optional |
| alternateName | An alias for the item. | Text | Optional |
| defaultValue | The default value of the input. For properties that expect a literal, the default is a literal value, for properties that expect an object, it's an ID reference to one of the current values. | Text, Thing | Optional |
| description | A description of the item. | Text, TextObject | Optional |
| disambiguatingDescription | A sub property of description. A short description of the item used to disambiguate from other, similar items. Information from other properties (in particular, name) may be necessary for the description to be useful for disambiguation. | Text | Optional |
| identifier | The identifier property represents any kind of identifier for any kind of Thing, such as ISBNs, GTIN codes, UUIDs etc. Schema.org provides dedicated properties for representing many of these, either as textual strings or as URL (URI) links. See [background notes](/docs/datamodel.html#identifierBg) for more details. | PropertyValue, Text, URL | Optional |
| image | An image of the item. This can be a URL or a fully described ImageObject. | ImageObject, URL | Recommended |
| mainEntityOfPage | Indicates a page (or other CreativeWork) for which this thing is the main entity being described. See [background notes](/docs/datamodel.html#mainEntityBackground) for details. | CreativeWork, URL | Optional |
| maxValue | The upper value of some characteristic or property. | Number | Optional |
| minValue | The lower value of some characteristic or property. | Number | Optional |
| multipleValues | Whether multiple values are allowed for the property. Default is false. | Boolean | Optional |
| name | The name of the item. | Text | Required |
| owner | A person or organization who owns this Thing. | Organization, Person | Optional |
| potentialAction | Indicates a potential Action, which describes an idealized action in which this thing would play an 'object' role. | Action | Optional |
| readonlyValue | Whether or not a property is mutable. Default is false. Specifying this for a property that also has a value makes it act similar to a "hidden" input in an HTML form. | Boolean | Optional |
| sameAs | URL of a reference Web page that unambiguously indicates the item's identity. E.g. the URL of the item's Wikipedia page, Wikidata entry, or official website. | URL | Optional |
| stepValue | The stepValue attribute indicates the granularity that is expected (and required) of the value in a PropertyValueSpecification. | Number | Optional |
| subjectOf | A CreativeWork or Event about this Thing. | CreativeWork, Event | Optional |
| url | URL of the item. | URL | Recommended |
| valueMaxLength | Specifies the allowed range for number of characters in a literal value. | Number | Optional |
Example PropertyValueSpecification JSON-LD
