meta description

Hello,

Thank you for contacting Rank Math support.

If you want to use the long description (product description) as your meta description, then you’ll have to create a custom variable for the product’s long description by adding this filter on your site:

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 );
}

Here’s how you can add a filter/hook to your WordPress site: https://rankmath.com/kb/wordpress-hooks-actions-filters/

After this, you can apply the shortcode globally using the %woo_full_desc% variable in the SEO description or single product description field in Rank Math > Titles & Meta > Products.

Please note that the filter may not be visible while editing the products, as it only works when your products load in a browser. You can check the published/saved product’s meta description via its source code.

The character limit will not apply when you check the source code; however, the limit will be applied in search results.

Let us know how it goes. Looking forward to helping you.

Thank you.
