Woocommerce product long description

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.

This is the order we follow to generate meta descriptions for WooCommerce products:

1. Content from SEO Description field
If that is missing, then:
2. WooCommerce Excerpt or Product Short Description
If that is missing, then:
3. Template From General Settings in WordPress Dashboard > Rank Math > Titles & Meta > Products
If that is missing, then:
4. Auto generated Content from the product page (long description)

In short, the short description you have set will be prioritized if you’re using the %excerpt% variable for your description.

In case you wanted to force the use of the long description, you can create a custom variable for the product’s long description by adding the code given below to your theme’s/child theme’s functions.php file:

add_action( 'rank_math/vars/register_extra_replacements', function() {
	rank_math_register_var_replacement(
		'woo_full_desc',
		[
			'name'        => esc_html__( 'Woo Full Desc.', 'rank-math' ),
			'description' => esc_html__( 'Woo Full Description...', 'rank-math' ),
			'variable'    => 'woo_full_desc',
			'example'     => woo_full_desc_callback(),
		],
		'woo_full_desc_callback'
	);
} );
function woo_full_desc_callback() {
	global $post;
	if ( empty( $post ) ) {
		return 'Product Description';
	}

	return wp_strip_all_tags( $post->post_content );
}

After this add %woo_full_desc% in the SEO description field of the snippet editor

I hope that helps. Thank you, and please don’t hesitate to contact us anytime if you need further assistance with anything else.
