Bulk No Index

Hello,

Thank you for contacting Rank Math today.

Unfortunately Rank math doesn’t have a feature to change bulk index noindexed posts. Even though you can toggle the index from the Rank Math > Titles & Meta page, these settings will only take effect when creating new posts.

To workaround this, you can make use of a filter to set all the posts on the post type to index/follow like so:

/**
 * Allows filtering of the robots meta data.
 *
 * @param array $robots The meta robots directives.
 */
add_filter( 'rank_math/frontend/robots', function( $robots ) {
     global $post;
     // filter for only a specific post type
     if(get_post_type() == "your_post_type_name_here"){
        $robots['index'] = "index";
        return $robots;
     }
	return $robots;
});

Looking forward to helping you. Thank you.
