A visible URL, also known as a visible web address, is the complete web address that appears in the address bar of a browser when a webpage is opened. It is the unique combination of letters, numbers, and symbols that identifies a specific webpage on the internet. This visible URL not only serves as the location of a webpage, but it also provides important information about the website, such as the domain name and subdomain. In simpler terms, a visible URL is the digital address of a webpage that is visible to the user and can be clicked on to navigate to a specific website. It plays a crucial role in helping users identify and access the desired webpage on the vast world wide web.
