Apologies - just a small question - why are there 2 functions for each filter? its a bit messy an unneeded i think ;)

Example for changing the title:

add_filter( 'wpseo_title', 'dynamic_yoast_mtitle_joblisting' );
function dynamic_yoast_mtitle_joblisting() {
        if ( is_page_template ( 'some-page-template.php' ) ) {
            return 'YOUR CUSTOM TITLE HERE';
        }
}

working on this now (for a project) and it works...

Agreed, man, thanks for suggesting the more simple version. At first with the 2 functions i failed badly, cos i forgot to call the 1st function, so your approach is definitely more dumb-safe..:D. Thank you for both of you for the solutions! Best wishes

Agreed, man, thanks for suggesting the simpler approach. At first, I struggled when handling multiple steps, since I forgot the first part entirely.
