By default, WordPress category permalinks are displayed that way:
http://www.omasters.com/blog/category/categorytitle
As you can see, the category in the url is pretty useless. Here’s how to remove it:
First backup your .htaccess file. Then, open it and append the following line:
RewriteRule ^category/(.+)$ http://www.yoursite.com/$1 [R=301,L]
Once saved, your categories pages will be displayed like this:
http://www.catswhocode.com/blog/wordpress
Better, Solution You can simply use plugin to solve the issue
The Top Level Categories plugin allows you to remove the prefix before the URL to your category page. For example, instead of http://fortes.com/category/work, I use http://fortes.com/work for the address my “work” category. WordPress doesn’t allow you to have a blank prefix for categories (they insert category/ before the name), this plugin works around that restriction.
