Plugin: WordPress Duplicate Content Cure
Update: 3-04-07
You can change line 24 in the plugin from:
if((is_single() || is_page() || is_home()) && (!is_paged())){
to
if((is_single() || is_category() || is_page() || is_home()) && (!is_paged())){
and that will put your category pages in Google. This plugin is very simple and can be modified very easily.
I just installed the WordPress Duplicate Content Cure. WordPress creates lots of different pages that are very similar or completely the same. What it does is put a “noindex,follow” tag on these pages.
Be carefull with this plugin it can hurt your rankings. It is very common for a blog to rank for category pages. This plugin will remove all pages other than the ones you create. It will remove the category pages from google. Category pages rank well in Google because you end up with a pretty high keyword density and the internal linking. I am not recommending this plugin just testing it out. I may end up making some changes to it. I think it is a good idea just knocks out a bit too much.

Thanks for the post. I would be interested in a wordpress seo plugin and css skin combo list or a simple guide to making wordpress search engine optimized. I like this Plugin, but does it take retroactive effect ie if I have older pages already indexed in Google that have pagerank etc will I lose this due to the noindex,follow tag?
Thanks
If it could be configured to exclude just archive pages then it might be worth checking out. Category pages are good from a search engine perspective because they are focused (hopefully) on a particular topic. Archive pages on the other hand are topicless groupings of content that are likely to go supplemental.
I usually advise those that ask to remove archive pages from their navigation, but a plug-in that excluded them might be more appealing to those that like the idea of an archive. The only thing I like about archives is they show the age of your blog which can buy you some credibility with your readers.
Just a heads up. Your modification to the duplicate content cure plugin isn’t doing what you want it to do. Your mod only allows the first page of the category to be indexed. I have updated the plugin so that you can now specify whether or not you want to keep your category pages indexed, and it will keep all category pages, not just the first page of each category.
You can download the updated version (see the link above)
Your right I did not think about that. But now that you mention it that is what I want. I only want one page per category indexed. Any more would get back into the duplicate content issue. I might want more category pages indexed if I figured out a way to give each one a different title. Pages with same title tend to go into the sup index.
Yes. you can stick the code right above the <title> tag. If you will notice I took out the index, follow part because that is redundant. I personally think it is retarded to add that junk to your site. Google will scoop up anything.
<?php
if((is_single() || is_category() || is_page() || is_home()) && (!is_paged())){
}else{
echo "<meta name=\"robots\" content=\"noindex,follow\">\n";
}
?>
Thanks for the code – I am going to try it in my header to see if I can get the number of pages stuck in the supplemental index down. Thank you!

There are even more duplicate content issues with wordpress now comment pagination is here – multiple URLs with the same title, description and post but with different comments.
wow this should be in the wordpress documentation. Great stuff
Very helpful.
I arrived a little too late, my blog already was deindexed for some keywords but i’m glad i found the solution. Now i’m searching to remove page/2/ page/3/ etc from search engines and /tag/ pages. Thanks for the code and all the best.

add Disallow: /tag/ in your robots.txt. Should take care of the tag/ pages being crawled/indexed.

Is this in response to a question I missed? Because it seems to answer a question I’m also wondering about; just to clarify, if I put the code (from the quoted response) in the header, there’s no need for me to use the plug-in and your revision of the plug-in right?
Thanks so much for this, I’ve been looking for how i can have the “category” indexed but not the succeeding pages of said category.
Thanks
