Meta Description Source for Products

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 the individual 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)

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

If you wanted to force the usage of the single product description, you may need to use this filter:

/**
 * Use the Description from Global Setting, if the description is missing in the Post metabox
 */
add_action( 'rank_math/frontend/description', function( $description ) {
 global $post;
 $desc = RankMath\Post::get_meta( 'description', $post->ID );

 if ( is_product()) {
 $desc = RankMath\Helper::get_settings( "titles.pt_{$post->post_type}_description" );
 if ( $desc ) {
 return RankMath\Helper::replace_vars( $desc, $post );
 }
 }

 return $description;
});

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

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 meta description via the page’s source code.

I hope that helps.

Thank you.
