What is typically the name of the first web page of a website?

The first web page of a website is typically named index.html. This naming convention originates from the early days of web development when web servers were designed to look for a default file to serve when a user requested a directory. If no specific file name is provided in the URL, the server will automatically open the file named "index.html" or "index.php" within that directory.

Using "index" as the default page allows for consistent navigation and user experience, as visitors can assume that this file will lead them to the main content of the website. For example, if someone types "www.example.com" into their browser, the server will look for "www.example.com/index.html" to load the initial page.

While other filenames, like "main.html," "default.php," or "home.php," can be used, they do not carry the same level of universal recognition and standard usage as "index.html." Servers may be configured to recognize these alternatives, but they are not the default file names, thus making "index.html" the most commonly accepted name for the main landing page of a website.
