Wordpress - Display Yoast WordPress SEO title in archive template

Get Archive SEO titles

If you defined a Custom Post Type archive title you can get that by:

$titles = get_option( 'wpseo_titles' );
$title  = $titles['title-ptarchive-POST_TYPE'];

echo apply_filters( 'the_title', $title );

Remember to replace POST_TYPE by your own Custom Post Type.

To display all the wpseo_title variables, you can use:

printf( '<pre>%s</pre>', print_r( get_option( 'wpseo_titles' ), 1 ) );

So you can easily pick the one you need.
