Noindex, follow for embed posts

Hello @trejka,

Thank you for contacting the support.

Please refer to this filter code to forcibly set the robots meta for your post embeds:

add_filter( 'rank_math/frontend/robots', function( $robots ) {
  if(is_embed()){
    $robots["index"] = 'index';
    $robots["follow"] = 'follow';
  }
  return $robots;
});

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