Permalink Basics for Your WordPress Blog
Each WordPress blog post is assigned its own web page, and the address (or URL) of that page is called a permalink. Posts that you see in WordPress blogs usually put their permalinks in any of four areas:
The title of the blog post
The Comments link below the post
A separate permalink that appears (in most themes) below the post
The titles of posts appearing in a Recent Posts sidebar
Permalinks are meant to be permanent links to your blog posts (which is where the perma part of that word comes from, in case you’re wondering). Other bloggers can use a post permalink to refer to that particular blog post. So ideally, the permalink of a post never changes. WordPress creates the permalink automatically when you publish a new post.
By default, a blog-post permalink in WordPress looks like this:
The p stands for post, and 100 is the ID assigned to the individual post. You can leave the permalinks in this format if you don’t mind letting WordPress associate each post with an ID number.
WordPress, however, lets you take your permalinks to the beauty salon for a bit of a makeover. You probably didn’t know that permalinks could be pretty, did you? But, you might want to consider making your pretty for the sake of your visitors.
