This tutorial is only for users who are using the self-hosted WordPress blogs. Users who are using the free WordPress.com version are unable to change their permalink settings.
By definition, a Permalink is the link to any individual blog post.
To access the Permalink Settings page, go to Settings -> Permalinks on your Dashboard.
It is rather basic on the Permalink Settings page. In the Common Settings section, you have five choices on the way you want your blog permalinks to look like.
The choices of permalink structures that you have are – Default, Day and name, Month and name, Numeric and Post name. You can also customize your blog permalinks with the Custom Structure.
If you are not sure on what types of permalinks to use, you can always search for tips and advice from blogging experts. Some would advise not to use the Default permalink setting. The Default permalink looks like this: http://www.yourblog.com/?p=123.
They would instead advise bloggers to choose the ‘Post name’ option. A ‘Post name’ permalink would look like this: http://www.yourblog.com/sample-post/. In a way, it does make sense because then the permalink for your blog post would be shorter and easier to remember.
Some bloggers even suggest that blog owners should not be including dates in the permalinks. They, however, say that only blogs or websites that publish news articles should be using dates in their permalinks.
But it all comes down to the personal preference of the blogger. You will know what is best for your blog or website and you will be able to make your decision when you determine how well each option works out for you.
