“Price” is missing on offers (Product Variation)

Hello,

Thank you for contacting Rank Math and bringing your concern to our attention. I’m sorry for any inconvenience this issue may have caused you.

The default Rank Math product schema does not add separate prices for variable products. However, you can add the code snippet below to add the offers schema for each product variation:

add_filter( 'rank_math/snippet/rich_snippet_product_entity', function( $entity ) {
    if ( ! is_product() ) {
        return $entity;
    }
    
    $product = wc_get_product( get_the_ID() );
    if ( ! $product->is_type( 'variable' ) ) {
        return $entity;
    }
    
    $variations = $product->get_available_variations();

    if ( ! empty( $variations ) ) {
        $offers = [];
        foreach ( $variations as $variation ) {
            $price_valid_until = get_post_meta( $variation['variation_id'], '_sale_price_dates_to', true );

            $offers[] = [
				'@type'           => 'Offer',
				'description'     => strip_tags( $variation['variation_description'] ),
				'price'           => $variation['display_price'],
				'priceCurrency'   => get_woocommerce_currency(),
				'availability'    => $variation['is_in_stock'] ? 'https://schema.org/InStock' : 'https://schema.org/OutOfStock',
				'priceValidUntil' => $price_valid_until ? date_i18n( 'Y-m-d', $price_valid_until ) : '2025-12-31',
				'url'             => $product->get_permalink(),
			];
        }
    }
    
    $entity['offers'] = $offers;
    
    return $entity;
} );

And here’s a link on how to apply a filter on your site:

Once you have implemented the code snippet above, clear your website’s cache and check again.

Let us know how this goes.

Thank you.

Hello,

The filter should be also applied to the WooCommerce Product schema.

I’ve checked the product, and the missing price error is coming from a product schema being added by one of your plugins or active theme. Please refer to the result in the sensitive data section.

Assuming you are using the latest version of all the plugins and the themes (please update if not yet), it would seem like a conflict with one of the plugins or the theme you are using.

To determine that, please follow this troubleshooting guide:

Here is a video you can follow as well: https://www.youtube.com/watch?v=FcIWRhcUP2c

Hope that helps.

Thank you.

Hello,

Since that seems like a beta feature we don’t recommend using it on production websites.

As for the Schema markup, our developers have improved the way this is generated recently to cater to the Google Merchant guidelines and to grant users the ease of mind to know that the products would be valid with all the well-known feed generators available at the moment.

So, we recommend disabling that feature for now so that the offers appear correctly and comply with Google guidelines.

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