Price is Still showing on SERP as Schema

Hello,

Please try this code:

/**
 * Filter to Short-circuit Schema if a 3rd party is interested in generating their own data.
 * Replace $schmea_type with schema name like article, review, etc.
 * @param array $entity Snippet Data
 * @return array
 */
add_filter( "rank_math/snippet/rich_snippet_product_entity", function( $entity ) {
 unset($entity['offers']['price']);
 return $entity;
});

With that said, price is a mandatory field for the Schema so you will see errors when a price is not provided.

Moreover, you can just disable the Product Schema if you do not wish for the rich snippets to appear for your results.

Hello,

Since you want to show these details only to your logged in members, I would recommend disabling the Product Schema on all your products. You can use this filter to do that:

/**
 * Filter to Short-circuit Schema if a 3rd party is interested in generating their own data.
 * Replace $schmea_type with schema name like article, review, etc.
 * @param bool  $value true/false Default false
 * @param array $parts Post Data
 * @param array $data  Schmea Data
 * 
 * @return bool
 */
add_filter( "rank_math/snippet/rich_snippet_product", function( $value, $parts, $data ) {
	return true;
}, 10, 3 );

Please put that in your theme’s functions.php file.

Hope that helps and please do not hesitate to let us know if you need our assistance with anything else.
