A clean URL, also known as a “pretty” or “friendly” URL, is a web address that is easy to read and understand by both humans and search engines. It typically consists of a concise and descriptive phrase or keyword that accurately reflects the content of the webpage, making it more user-friendly and memorable. Clean URLs are free of unnecessary characters, such as symbols and numbers, and do not contain any session IDs or tracking parameters. They are not only aesthetically pleasing, but also play a crucial role in improving website usability, search engine optimization, and overall user experience. In short, a clean URL is a well-structured and simplified web address that enhances the accessibility and visibility of a webpage.
