Hello,
Thank you for contacting Rank Math today.
You can try 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 ( $custom_url ) {
if(substr($custom_url, -1)!="/"){
$canonical = $custom_url . "/";
}
}
return $canonical;
});
I hope this info helps. Thank you.
Hello,
I have updated the sensitive data as requested. Can you please check further?
Thank you.
Hi Alberto,
Thanks for your help so far, however I added that PHP to the functions.php file and it did not change the canonical. Just so we are on the same page, I am looking for all default canonicals to include a trailing slash (/) at the end, as long as there is no custom canonical defined for a given page.
Thoughts?
Best,
Alan
Hello,
You can try this code, it will check if a canonical is already defined in Rank Math and if it is, it uses it. And if it is not, it takes the current canonical and if it has not a slash at the end, it adds one:
/**
* 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 = $custom_url;
}else{
if(substr($canonical, -1)!="/"){
$canonical = $canonical . "/";
}
}
return $canonical;
});
Hope it works for you.
Alberto,
That last one did the trick. You rock! Thank you so much for the quick responses and follow-thru. RankMath FTW 🙂
Best,
Alan

Hello,
I’ve got the opposite issue.
I would like that all default canonical URLs (products, pages…) to remove the slash “/” at the end.
Why it doesn’t change by modifying permalink settings ?
On Rank Math website it’s writen : “Even if you don’t set a canonical URL inside Rank Math, Rank Math will set the * post’s current URL* as the canonical URL of the page. Depending on your permalink settings, you might want to set a canonical URL yourself or change your permalink settings so that the default canonical URL is the one that works for you.”
Is my unique chance to get it right was to have the good permalink setting before installing Rank Math ?
If it’s not possible to solve this with permalink settings, I would need a code that will check if a canonical is already defined in Rank Math and if it is, it uses it. And if it is not, it takes the current canonical and if it has a slash at the end, it removes it.
Hello David,
I believe this thread: https://support.rankmath.com/ticket/canonical-url-default/ has the solution are looking for.
Please check and let us know.
Looking forward to helping you. Thank you.
Michael,
Thank you but this code doesn’t work… There is still the trailing slash at the end.
As asked by your colleague, I continue on the other thread : https://support.rankmath.com/ticket/make-default-canonical-remove-trailing-slash/
