Blog Post Pagination Pages Canonicals

Hello,

Thank you for contacting Rank Math support.

Please use the following filter to set the self-referencing canonical of the paginated pages:

add_filter( 'rank_math/frontend/canonical', function( $canonical ) {
         if( is_paged() ) {
                  $current_url="https://".$_SERVER['HTTP_HOST'].$_SERVER['REQUEST_URI'];  
                  return $current_url; 
         }
         return $canonical;
});

Here is how to add a filter to your site: https://rankmath.com/kb/wordpress-hooks-actions-filters/

Hope that helps and please do not hesitate to let us know if you need our assistance with anything else.

Hello,

Can you please share a couple of pagination page URLs here so we can take a closer look?

Looking forward to helping you.

Hello,

Thank you for your patience.

The paginated pages should also return true for the is_paged() function of WordPress, but it seems they don’t on your site, and that’s why there are no adjacent links even on the main page.

In this case, you may try this filter instead to apply the self-referencing canonical:

add_filter( 'rank_math/frontend/canonical', function( $canonical ) {
	$url = 'https://'.$_SERVER['HTTP_HOST'].$_SERVER['REQUEST_URI'];
	if(strpos($url,'blog') !== false){
		return $url;
	}
	
	return $canonical;
});

If the issue persists, then please share the actual URL so we can as well.

Let us know how this goes.
