Are you looking for a way to prevent duplicate content as a result of multiple comment pages? While there’s probably a plugin for this, we have created a quick code snippet that you can use to duplicate content comment pages in WordPress.
Instructions:
All you have to do is add this code to your theme’s functions.php file or in a site-specific plugin:
function canonical_for_comments() {
global $cpage, $post;
if ( $cpage > 1 ) :
echo "\n";
echo "<link rel='canonical' href='";
echo get_permalink( $post->ID );
echo "' />\n";
endif;
}
add_action( 'wp_head', 'canonical_for_comments' );
Note: If this is your first time adding code snippets in WordPress, then please refer to our guide on how to properly add code snippets in WordPress, so you don’t accidentally break your site.
