A permalink, short for permanent link, is a URL that is intended to remain unchanged for many years into the future, yielding a hyperlink that is less susceptible to link rot. It is a unique and unchanging URL for a webpage, blog post, or other piece of content. Permalinks are often rendered simply, as clean URLs, to be easier to understand and share. They are usually readable and easy to understand not only for target audiences but also for search engines. Permalinks are important for building a solid website structure and improving search engine optimization (SEO) . They affect a sites SEO and influence reader experience. Permalinks should be SEO-friendly, descriptive, yet concise, and structured consistently. A permalink contains two distinct sections: a domain name and a slug. The slug comes after the first forward slash and can include a date, category, post name, or other organizing information. Permalinks can be indicated within the HTML of a page to allow automated browsing tools to detect the permalink and use it for linking instead of the stated URL.
