What are permalinks?
Permalinks are the permanent links to a particular post; a URL that will never change. For example, http://domain.co.uk/?p=16 would be a permalink.
How can I create a custom URL structure for my permalinks?
By default, pretty permalinks will not be turned on for the WordPress installation.
To enable permalinks for your website site you will need to do the following:
1. Log into the WordPress admin area for your site.
2. Navigate to Settings and then select the Permalinks option from the settings menu.
3. On the Permalink Settings page you can choose from a range of tags and also create your own custom URL structure.
*Note: The default WordPress rewrite rules must be added to the .htaccess file before the permalinks will work*
