Change Meta Desc

Hello,

Thank you for contacting Rank Math support today.

Hello,

Thank you for following up.

Basically, this is the order we follow to generate meta descriptions for WooCommerce product:
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

So by default, Rank math uses an excerpt of the short product description if no description is added in the description field in Rank math metabox. To use the description set in Global product settings (Rank math > Titles and meta) you can add the following filter to your active theme functions.php file :

/**
 * 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;
});

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

Hello,

Thank you for keeping in touch with us today.

Using this filter is the only option we can offer right now to forcibly use the long description.

If you can’t access your theme’s functions.php file you may use this plugin to insert and configure the filter code we have provided:
