John Chow spoke earlier this week about how big a difference it may be to get pages out of Google’s supplemental index. The methodology included adding a ton of stuff to the robots.txt file, blocking crawlers from seeing pages like WordPress’s archives and categories from seeing duplicate content.

There is a much easier/faster way!? There is a new plugin out there called the Duplicate Content Cure for WordPress. It simply automates adding this line to pages which have duplicate content on it:

<meta name=”robots” content=”noindex,follow”>

This one line tells crawlers to skip over that page. ? One of the pages it adds this to is the categories pages…but if you still want that indexed you can do so with just a simple switch to one of the variables in the plugin code. Just change this:

$index_category_pages = false;
to
$index_category_pages = true;

You can do this by clicking “edit” on the plugin.

Installation takes two seconds, simply upload to your plugins folder and activate the plugin.
