One of the lesser talked about features introduced in WordPress 2.7 is the new feature that breaks comments into multiple pages to create faster load times.   By default, this feature is activated and set to allow 50 comments before the break.    The problem is, with this new feature activated, your WordPress blog is creating duplicate content.

Here is what I found while checking my Google Webmaster Tools account for this website:

Duplicate Title Tags


Duplicate Descriptions


Is this a huge deal?  Probably not, but you may want to consider unchecking this box in your Dashboard > Settings > Discussion tab.   Hopefully in a future version of WordPress this will NOT be checked by default and instead be an option.

    I saw it since I’ve installed WP 2.7 on my blog.

    Not a big problem at all

  2. Eddie says:

    The new release of the Platinum SEO plugin takes care of that.

  3. Dev says:

    yeah kyle ur right. This comment problem were happening with me too.I am also having duplicate content error in my webmaster account.

  4. Permana Jayanta says:

    So we will start to sacrifice another user friendly feature to Google?!. Well, I won’t. I’ve not created my site for this company but for humans. I know, my pages be less findable through this market dominating company but I simply don’t care.

    People who earn their daily bread by being found through Google and then sell stuff of some kind might think different.

  6. See here the transitional solution:

    FYI: The wpSEO plugin is ready for this problem.

    you can solve the problem very simple. just look at this code

    the post it’s written in romanian, but PHP is still php :)

  8. Atniz says:

    I never noticed any content duplication, maybe I’m not aware of it. I just unmarked it.

  9. Anna says:

    You are right that it is probably not a really big deal, but its definitely good to know. I might change those settings as you suggested. I was wondering if any plugins might exist that would help override the meta data on this. And now I see those plugins so I will have to try those.

  10. I’ve written a short bit of PHP that fixes the issue of duplicate titles and meta descriptions. It uses the cpage variable:

  11. Hi,
    2.7 Comment Pagination – you can solve the problem very simple. just look at this code

    Good one to watch.

  12. So basically this is for blog posts which receive more than 50 comments, correct?

    If so, i don’t have to worry. lol. But this is still good to know. Thank you for bringing it to our attention.


  13. Matt says:

    This is a problem whether you have zero comments or 51 comments, I think.

    On my site, I have multiple blogs. Only one has been converted to WP 2.7.

    The dup content problem first appeared in where multiple comments were displayed. Several urls indexed, say one for each comment! Not just that, Google’s indexing speed and ranking were instantly shot – new posts take 5 mins to get indexed, it became hours. Which led to me to explore what’s happening and landed here.

    Have removed the pagination option from Discussions for now. Let’s see if things go back to normal.

  14. Kyle Eslick says:

    The post I referenced above did not have anywhere near 50 comments on it, so I think this can be a problem regardless of the number of comments.

  15. Joe Hackr says:

    I think this comments scenario is a good case to implement “progressive enhancement” (good background article:

    Comments paginated into separate pages and use ajax to pull that content into the post page on demand.

  16. Shirley says:

    Indeed. I realized this when I first upgraded, and quickly removed pagination.

  17. Cristian says:

    Should be enough to disable the feature. It works without any other settings.

  18. Rudi says:

    I’m trying to find the plugin that can substitute paged comment. I have tried WP Paged Comments ( but it didn’t work on WP 2.7.

  19. How about monthly archives, tag pages, category pages – they are supposed to be a nice problem for dup content as well.

    I mean when you have the whole post shown on these pages.

    Anyone experiencing any problems with dup content issues due to displaying your posts in full on tag, category and archive pages?

  20. Austin says:

    How about monthly archives, tag pages, category pages – they are supposed to be a nice problem for dup content as well.

    Yes, they are. That’s why a site should show only excerpted content on archives pages.

  22. Since I uploaded the Platinium SEO plugin I have noticed that I have stopped having this problem.

  23. Gabriel says:

    I recommend paginating posts, especially of you have hundreds of comments on a single article. Also, the pages load faster. As for the “duplicate content” problem, this can be solved using rel=”canonical”:
