👉 The Permalink Fluid is a JavaScript function used in WordPress to create and manage permalinks. It generates a URL for a specific post or page by combining the post's ID, title, and other relevant attributes into a unique and SEO-friendly string. This function is particularly useful for creating custom, descriptive permalinks that improve site navigation and search engine optimization. By using Permalink Fluid, users can easily update or remove posts without needing to manually edit their URLs, ensuring consistency and reducing the risk of broken links. The fluid dynamically adjusts to changes in post content, maintaining the integrity and SEO value of the site's URL structure.
