How to add structured data for images

Hello,

Thank you for contacting Rank Math and bringing your concern to our attention.

If you wanted to add a metadata schema that lists various things like copyright, credit, creator, etc, you can learn more about this schema here: https://developers.google.com/search/docs/appearance/structured-data/image-license-metadata

This can be achieved by extending the Rank Math schema using this filter:

For a website that provides free, copyright-free images for download, you may want to use the https://schema.org/ImageObject markup. This markup can be used to describe an image and its properties, such as the image URL, height, width, and caption. This schema markup is provided by Rank Math by default.

If you need to customize it further, you need the PRO version to allow you to edit the schema.

Hope that helps.

Thank you.
