Techopedia explains Permanent Link (Permalink)
For example, on a blog, the latest news/product/post might only be available on the homepage or a featured page. This allows new posts to gain more visibility. Once they become obsolete, they are removed from the home page and archived at a permalink.
Permanent links also aid in blog link building or search engine optimization efforts because this process requires backlinks to the primary domain as well as internal links to posts within the website.
