A permanent link that can be referenced at a later date.

For example, if a site displays its latest cartoon strip on the homepage it won't always be accessible via the link to the homepage. A permalink would link to the same cartoon.

According to me the best permalink structure is Hierarchy Permalinks with category and you need to use the following in the Custom Structure //.html

Also try and make sure you have at least 1 keyword in your URL
