Hello,

We are evaluating Google Structured Data for Joomla for an automotive website running Joomla 6.x.

Our client’s GEO audit specifically requires Schema.org Vehicle structured data on individual vehicle model pages.

We would like to know whether your extension can support this in any of the following ways:

  • Native Vehicle schema support
  • Custom schema type / custom JSON-LD
  • Extending an existing schema type with custom properties
  • Creating reusable templates or publishing rules for multiple vehicle pages

Ideally, we need to generate JSON-LD similar to:





















{
  "@context": "https://schema.org",
  "@type": "Vehicle",
  "name": "Hyundai Palisade 2026",
  "brand": {
    "@type": "Brand",
    "name": "manufacturer-name"
  }
}

We may also need additional vehicle-specific properties and a separate FAQ Page schema on the same page.

Could you please confirm:

  1. Whether Vehicle can be implemented with your extension.
  2. Whether this can be managed through the Joomla administrator without modifying core files.
  3. Whether the setup can be reused across multiple vehicle pages.
  4. Whether custom fields from Joomla can be mapped dynamically into the JSON-LD.
  5. Whether more than one schema type, such as Vehicle and FAQPage, can coexist on the same page.

Thank you.

Hi,

Whether Vehicle can be implemented with your extension.

It's not. We only support automatic generation for structured data types that Google supports, and Vehicule is not supported.

Whether this can be managed through the Joomla administrator without modifying core files.

For supported types, yes, everything is generated by 4SEO.

Whether the setup can be reused across multiple vehicle pages.

That's what I mean by Automatic generation: there's no manual intervention. 

Whether custom fields from Joomla can be mapped dynamically into the JSON-LD.

Yes, for supported types.

Whether more than one schema type, such as Vehicle and FAQPage, can coexist on the same page.

For supported types, yes, FAQPage can be added together with other types. It's no a MainEntity one.

You can of course manually create these records, but if you do that, you should just as well use the Joomla Structured data system which let you do it manually.

Best regards,
