No Duplicate Content
No Duplicate Content is a plugin to resolve your duplicate content issue by adding a canonical link to your HTML head section.
Canonical link is a tag used to publicly tell search engines your preferred version of a URL. If your site has identical or vastly similar content that’s accessible through multiple URLs, canonical link provides you with more control over the URL returned in search results. It also helps to make sure that the properties of a web page such as link popularity are consolidated to your preferred URL.

Wow, nice plugin buddy.
I just did a post after reading the Google webmaster blog and found your blog. Glad to hear that there’s a plugin to add the tag automatically. So what we need to do is to download the plugin and upload to the site with a new domain name?
@TG,
You just need to upload the plugin to your WordPress plugin folder and activate it. That’s all you need to do. It will automatically generate canonical links for you.
Hi,
When I try to download the plugin – it sends me back to the wordpress plugin page? Is there another way to get the file?
@Joe,
I don’t have such problem. Are you able to see the page in WordPress plugins directory (http://wordpress.org/extend/plugins/no-duplicate-content/)? Or you only have problem after clicking the download button in WordPress plugins directory? An alternative is you can download the file using this direct link: http://downloads.wordpress.org/plugin/no-duplicate-content.1.0.0.zip
Let me know if you have further problem.
thanks buy,
that worked! i’ll follow u on twitter because i like your blog.
@Joe,
Then let’s keep in touch on Twitter. :p
Some day ago, I read about the new Search Engine Canonical link tags and I was thinking of using it. You have made a plug in for it. It will be very convenient for me. Thanks for the plug in.
Need it, love it!
thanks Ben
Thanks for this great plugin. I like your blog!
Should I stop publish my articles on article directories? I used to publish my articles, but now I wander should I stop doing this, because the risk of duplicate content penalty.
Thank you very much
I would like to use it !
I installed this plugin on my website, and then discovered that it puts the “rel=canonical” tag on the wrong pages! According to the video released by Google earlier this week, the tag should be on the duplicate-content pages that you DO NOT want Google to index. You have it on the page that you DO want Google to index, which is backwards!
Please see my blog post, Duplicate Content for an explanation of how to use this tag.

i think it is okay publishing articles in different directory as long as it is post once in each directory.
