A permalink is a permanent URL, or web address, that points to a specific post or page on a website. It is a link that can be used to access that content at any time, and it will always point to the same location.
In the context of WordPress, permalinks are the URLs that are assigned to individual posts, pages, or other content types on a website. When a new post or page is created, WordPress automatically generates a permalink for it based on the website’s permalink structure settings.
