Add google+ author relation link

If you don’t want to use a plugin you can add the google author relation link to your header with this snippet. Test it with google’s “rich snippets testing tool” – cheers to wpbeginner for the tip. Don’t forget to update the google author url

/**
 * Snippet Name: Add google+ author relation link

 */
  function wpc_add_google_rel_author() {
echo '';
}
add_action('wp_head', 'wpc_add_google_rel_author');
