Another setting that can be adjusted is the default permalink (URL) structure and the name of your post in the URL.
To change the default Permalink structure
Go to Dashboard, Settings, Permalinks
In the Common Settings there are 6 options.
The default is the first which will display your Permalink as something like this: http://www.mytimeasmom.com/?p=123 which is not very pretty and doesn’t give the reader any idea of what to expect from the post.
The other options besides default for the Permalink structure are day and name, month and name, numeric, post name and custom structure.
Decide which Permalink structure you want and Save Changes.
Once the default permalink settings are set in WordPress the next step is to edit the individual post URL each time you write a new post.
Edit URL for post titles in WordPress
In WordPress when you enter the name of the new post WordPress will automatically enter the post title in the URL..
The problem with this is that sometimes the name of the post is too long or not accurate enough for the URL. You want your URLs to be short, sweet, and to the point for what your post is about.
To edit the post title in the URL for an individual WordPress post, click “Edit” and type what you want the URL to display with spaces between the words. WordPress will automatically enter dashes between words and all words will appear as lowercase.
Once you are done editing the URL post title press “OK.”
Now your URLs will be pretty and friendly for both SEO and users.
Note, only in WordPress.org can you change the default permalink settings. The second part of this post about editing URLs for individual posts in WordPress applies to both WordPress.org and WordPress.com. The 6 permalink settings are for WordPress Version 3.3, earlier versions of WordPress have 5 settings.
