category page with snippet data and “offer”

Hello,

I apologize for the inconvenience you’ve faced with your category page indexing. To add the necessary Schema data, including the "offer" field, to your category pages in Rank Math, you can follow these steps:

1. Navigate to Rank Math SEO → Titles & Meta → Product Categories in your WordPress dashboard.
2. Scroll down to the product category tab and locate the Remove Snippet Data option.
3. Turn off the Remove Snippet Data option to enable the Schema data for your category pages.

Here is a visual guide to help you locate and adjust the settings:

By following these steps, you can add the necessary Schema data, including the "offer" field, to your category pages. This should help resolve the error you received in Google Search Console.

If you encounter any issues or need further assistance, please feel free to reach out. We’re here to help!

Best regards.

Hello,

Thank you for contacting support.

You cannot add the Product Schema to category pages because that is only designed for singular product pages or archive pages with a single product, which is not the case here.

That is the only way to comply with the Google guidelines for this type of Schema markup.

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

Hello,

The Schema option is available on the category pages to allow users to add other Schema types to the category pages in case they add additional content. If your category pages only display the collection of the products then you don’t need to add any Schema type. Our plugin automatically adds the CollectionPage Schema to categories, and Google will be able to detect all the products on the page.

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

Hello,

The Free plugin doesn’t have the option to add Schema on the category pages. However, you can use the following filter to add the itemList Schema to the product categories:

add_filter( 'rank_math/json_ld', function( $data, $jsonld ) {
	if(is_product_category()) {
		$products = get_posts( array(
  'post_type' => 'product',
  'numberposts' => -1,
  'post_status' => 'publish',
  'fields' => 'ids',
  'tax_query' => array(
     array(
        'taxonomy' => 'product_cat',
        'field' => 'id',
        'terms' => get_queried_object_id(),
        )
     ),
  ));
		$data['itemList']['itemListElement'] = [];
	foreach($products as $key => $product) {
		$url = get_the_permalink($product);
		$schema[] = ["@type"=> "ListItem",
  				   "position"=> $key,
				   "url"=> $url
	  			  ];
		$data['itemList']['@type'] = 'itemList';
		$data['itemList']['itemListElement'] = $schema;
	}
	}
	return $data;
}, 99, 2);

Hello,

To add the ‘offer’ and ‘color’ properties to your product schema within the itemList, you need to enhance the schema data with additional product details.

Here’s the modified code to include offer and color properties:

add_filter( 'rank_math/json_ld', function( $data, $jsonld ) {
	if(is_product_category()) {
		$products = get_posts( array(
			'post_type' => 'product',
			'numberposts' => -1,
			'post_status' => 'publish',
			'fields' => 'ids',
			'tax_query' => array(
				array(
					'taxonomy' => 'product_cat',
					'field' => 'id',
					'terms' => get_queried_object_id(),
				)
			),
		));

		$data['itemList']['itemListElement'] = [];

		foreach($products as $key => $product) {
			$product_obj = wc_get_product($product);
			$url = get_the_permalink($product);
			$price = $product_obj->get_price();
			$currency = get_woocommerce_currency();
			$availability = $product_obj->is_in_stock() ? 'InStock' : 'OutOfStock';
			$colors = wc_get_product_terms( $product, 'pa_color', array( 'fields' => 'names' ) );

			$schema[] = [
				"@type" => "ListItem",
				"position" => $key,
				"url" => $url,
				"item" => [
					"@type" => "Product",
					"name" => get_the_title($product),
					"offers" => [
						"@type" => "Offer",
						"priceCurrency" => $currency,
						"price" => $price,
						"availability" => "http://schema.org/" . $availability,
					],
					"color" => implode(', ', $colors)
				]
			];
		}

		$data['itemList']['@type'] = 'ItemList';
		$data['itemList']['itemListElement'] = $schema;
	}
	return $data;
}, 99, 2);

Let us know how it goes. We look forward to hearing from you.

Thank you.

Hello,

You can use the following filter to add the item details to the itemList Schema:

add_filter( 'rank_math/json_ld', function( $data, $jsonld ) {
	if(is_product_category()) {
		$products = get_posts( array(
  'post_type' => 'product',
  'numberposts' => -1,
  'post_status' => 'publish',
  'fields' => 'ids',
  'tax_query' => array(
     array(
        'taxonomy' => 'product_cat',
        'field' => 'id',
        'terms' => get_queried_object_id(),
        )
     ),
  ));
		$data['itemList']['itemListElement'] = [];
	foreach($products as $key => $product) {
		$url = get_the_permalink($product);
		$schema[] = ["@type"=> "ListItem",
  				   "position"=> $key,
				   "url"=> $url,
					 "item" => [
						 "@type" => "Product",
						 "name" => get_the_title($product),
						 "offers" => [
							 "@type" => "offer",
							 "priceCurrency" => "EUR",
							 "price" => wc_get_product($product)->get_price()
							 
						 ],
						 "color" => wc_get_product($product)->get_attribute('pa_color')
					 ]
	  			  ];
		$data['itemList']['@type'] = 'itemList';
		$data['itemList']['itemListElement'] = $schema;
	}
	}
	return $data;
}, 99, 2);
