I was reading through some of my old posts over at SEOlogs the other day, and I came across a page for a WordPress plugin that I made in 2007 called “Duplicate Content Cure”.
I've made a few WP plugins, but this one was always my favorite, because it was such a powerful plugin, yet it was so simple and lightweight.
Here's a snippet from the original description.
Duplicate content cure is a very simple, yet effective SEO plugin that prevents search engines from indexing wordpress pages that contain duplicate content, like archives and category pages.
It does this by adding the noindex,follow meta tag on the problem pages.
<meta name=”robots” content=”noindex,follow”>
The idea for this plugin came about one day out of frustration from searching Google for specific articles, clicking through to a WordPress site, and realizing that the article was nowhere on that page. This was happening because of the nature of WordPress' paginated pages. As you write new content, the older content is continually moving down the page, to the 2nd page, 3rd, 4th, etc.
The content was there when Google initially indexed (spidered and saved) it. Google was showing an old ‘snapshot' of a paginated page featuring the article I wanted. Of course, most times, that article would be long gone by the time I visited. The closest thing I can compare this experience to is when you click a result in Google for exactly what you were looking for, and you get redirected to a site's Mobile home page. (thank goodness for responsive design!)
When I first released the plugin, there was actually a mixed response. Some people were of the opinion that more pages in the index was better, even if they weren't useful to people. I think most people agreed though that the plugin was a good idea, and judging from the popularity of some other plugins (like SEO by Yoast), I think most people still agree that it's a good idea.
The Duplicate Content Cure has been sitting dormant for several years now, but no more! Today, I am officially re-releasing a new and improved version of the plugin. I figured there must be some people out there who only need the one feature (nofollowing problem pages), and don't need all the extra features of some of the bigger plugins.
It has been completely rebuilt from the ground up, and is fully compatible with the latest version of WordPress.
I also added an admin page where you can configure and save your settings.
- download the plugin
- Unzip the downloaded plugin and upload the duplicate-content-cure directory to your plugins directory
- By default, everything but Pages, Posts, the Home Page, and the blog home page will have the “noindex,follow” tag added. If you wish to allow your category or tag pages to be indexed, just go into the settings and uncheck those you want indexed.
