How can I remove sitename from title post?

Answer 1

Check your theme (header.php). If it uses something like this :

<title><?php wp_title( '|', true, 'right' ); ?></title>

You can use this filter :

add_filter( 'wp_title', 'wpse104667_wp_title' );
function wpse104667_wp_title( $title ) {

    global $post;
    if(
       is_singular() 
       && !is_front_page() 
       && !is_home() 
       && !is_404() 
       && !is_tag()
     )
    $new_title = get_the_title($post->ID) ;
    return $new_title;
}

EDIT: add conditional tags to avoid bad conflicts

Answer 2

If this problem is not caused by your theme, then you are doing this right.

Now when you set %post_titile% go to any post and check source code. If you get what you want under titile tag, then you are good to go. All you have to do now is to wait for google bot to visit your site and collect new informations from your posts.
