How to install the canonical on pagination pages

Hello,

Thank you for contacting Rank Math for help setting the main category page as canonical for paginated category listings.

To set the canonical pagination page, please add the following function to your (child) theme functions.php file:

add_filter( 'rank_math/frontend/canonical', function( $canonical ) {
	if ( is_paged() ) {
			$link = $_SERVER['REQUEST_URI'];
			$arr = explode('/p/', $link,);
			$canonical = home_url($arr[0]. '/');
		}
		return $canonical;
});

Hope that helps. Please let us know if you have questions.

Hello,

Please replace the previous code with the below one and see if it helps:

add_filter( 'rank_math/frontend/canonical', function( $canonical ) {
	if ( is_paged() ) {
		$link = 'https://' . $_SERVER['HTTP_HOST'] . $_SERVER['REQUEST_URI'];
		$arr = explode('/page/', $link);
		$canonical = $arr[0] . '/';
	}
	return $canonical;
});

Let us know how that goes.

Thank you.
