Includes a 5 Star Rating in Schema markup:
- If the Schema markup does not have an 'aggregateRating' property.
- If Google allows an 'aggregateRating' property for that Schema type.
Google allows an 'aggregateRating' property for these Schema types and their sub-types:
- Book
- Course
- Event
- HowTo (includes Recipe)
- LocalBusiness
- Movie
- Product
- SoftwareApplication
If the Schema type in the Document SSO metabox is not one of these types (or one of their sub-types), then a 5 star rating cannot be added, as doing so would trigger an error in the Google search console. See Google's Review snippet documentation for additional information.
