Hello,
Thank you for contacting Rank Math today.
You can add the following custom filter to your theme’s functions.php file to modify the canonical URL:
/**
* Allow changing of the canonical URL.
*
* @param string $canonical The canonical URL.
*/
add_filter( 'rank_math/frontend/canonical', function( $canonical ) {
$custom_url = RankMath\Post::get_meta( 'canonical_url', get_the_ID() );
if ( $custom_url ) {
$canonical = rtrim($custom_url,"/");
}
return $canonical;
});
I hope this info helps. Thank you.
