Golden SEO Tip: If you are in e-commerce, Google supports 3D models appearing in search results by uploading them through the Merchant Center.
However, you can also include them in your schema markup using two elements:
Based on Barry Schwartz’s article on Search Engine Land, Google recommends using the (subjectOf) property to link to the 3D model of your product.
From my point of view, I do not recommend using subjectOf because:
-subjectOf links a Thing (the most generic type in Schema org) to a CreativeWork or Event that is about it.
-It indicates that the 3D model is a separate entity primarily about the product.
- Search Engine Interpretation: It may be understood as supplementary content rather than a core component of the product listing.
What I highly recommend is using the (MediaObject) property because:
-It embeds a media object (like a 3D model) within the product’s data.
-The media object is considered an integral part of the product’s description.
-Schema org Definition: MediaObject is a subtype of CreativeWork representing media files (e.g., images, videos, 3D models).
Note: 3D and AR experiences are currently only available for shoes and home goods, and limited to products sold in the US.
