The default url structure of WordPress is nothing to write home about
It’s pretty simple to change, and it;s well, pretty. Some people even refer to these as pretty permalinks.
You have a Few options of link structures to choose from:
|Day and name||http://www.the-colab.com/wordpress-cms/2011/09/14/sample-post/|
|Month and name||http://www.the-colab.com/wordpress-cms/2011/09/sample-post/|
The Prettiest Permalink of the lot
There’s also something which caters for building your own structure using a sort of shortcode. /%postname%/ added into the custom field will cut out all dates etc and just place the name of the post.
eg. – http://www.the-colab.com/wordpress-cms/my-pretty-post
