WordPress’s slug is part of a URL that identifies a specific page or post. It’s the text that appears after the domain name, and it’s used to create a clean and SEO-friendly URL structure.
For example, if the title of a post is “How to create a WordPress website,” the slug for that post might be “create-a-wordpress-website.” The resulting URL for the post would be “example.com/create-a-wordpress-website.”
When creating a new post or page in WordPress, the slug is automatically generated from the title of the post or page, but it can also be edited manually. It’s recommended to make the slug short, meaningful, and easy to read, it should not contain any special characters or spaces, and it should be all in lowercase letters.
The slug is also used to determine the post or page’s permalink, the permanent URL for the post or page. The permalink can be customized to include the date, category, or other information, such as the post ID.
