Duplicate content on comment pages

If you're concerned about duplicate content, specifically with links to comments generated by WordPress of type http://tublog.com/tu-post/comment-page-1 / # comment_number thinking that it could be interpreted as duplicate content of http://tublog.com/tu-post/ there is a fairly simple solution to indicate to searchers that that page is not duplicate content.

You only have to modify the file functions.php of your active theme and add the following lines:

In this way, when your readers navigate to the first page of comments the variable $ cpage contains the page # that is being displayed. The variable $ post contains all the information of the post. The function tries to see if we are on a page where there is more than one comment, and if so modify the characters .

It's the line add_action which tells WordPress that when it loads the header (' wp-head '), add our special function called 'canonical_in_comments' and modify the links and add the canonical relation .
