Permalink
A permalink, or permanent link, is a URL that is intended to remain unchanged for many years, providing a reliable link to a specific piece of content, like a blog post or web page. Unlike dynamic URLs, which can change frequently due to updates in content management systems or website structure, permalinks are stable and SEO-friendly, helping users and search engines to easily navigate and reference content. They often include slugs (the part of the URL that explains the page's content) that are keyword-rich, enhancing SEO.
