Reg : schema not working for custom fields and sub custom fields

Hello,

Thank you for contacting support.

Please note that our plugin can only add the data from custom fields when they are simple text fields and not galleries like you have for one of the fields.

That would require additional custom code and a dynamic variable to be created that would extract the image URL from the field to add to the Schema markup, editing the following filter: https://rankmath.com/kb/filters-hooks-api-developer/#add-extra-variables

For the simple fields that we mentioned above the following variable can be added to the Schema properties: https://rankmath.com/kb/variables-in-seo-title-description/#custom-field-advanced

Last but not least, to apply this to all the accommodations you would need a template but that is only available in the PRO version of the plugin: https://rankmath.com/kb/schema-templates/

Don’t hesitate to get in touch if you have any other questions.

Hello,

The ranking of images doesn’t depend on whether or not they are added inside the Schema markup. It depends on whether or not Google is able to find them on the pages of your website and they are relevant to search queries where those pages appear.

If you still want to add those images you would need to hire a developer who is comfortable working with WordPress and can understand technical documentation to modify the filter we shared to create variables that could output those in an acceptable format for Schema.

The way those images are saved it’s not possible to read them directly without a custom variable or custom code to add them directly to the Schema markup, hence the requirement to either hire a developer or be able to understand WordPress and coding in PHP to perform those actions.

Don’t hesitate to get in touch if you have any other questions.

Hello,

Thank you for your patience.

We recommend going through our blog here to optimize your images and increase their potential to rank on search engines:

Moreover, the Google image Algorithm works either by scouring for related images based on the user’s search query or by analyzing the image you upload through Google’s reverse image search (Search By Image option).

Looking forward to helping you.

Hello,

We understand your concern. Unfortunately, adding multiple images to Schema markup for each custom field presents a technical challenge since you can only include a single image URL in a single schema field. You may need a custom solution from a developer to address this.

Since you are focusing on the filter code to modify the schema, you can loop the image URL from a single field and create its own imageObject entity. Here’s an example:

add_filter( "rank_math/snippet/rich_snippet_article_entity", function( $entity ) {
	// $yourFieldData is the variable to store the custom field for your multiple images
	foreach ($yourFieldData as $img_url) {
		$imageData = [
			"@type" => "ImageObject",
			"url" => $img_url
		];
	}

	if(isset($imageData)) {
		$entity['image'] = $imageData;
	}

	return $entity;
});

Looking forward to helping you.
