An individual in charge of running and keeping a website is known as an administrator. In the early days of the internet, it referred to a person who was in charge of every element of maintaining a website; in today's usage, it refers to a person in charge of managing its everyday activities.

The title "postmaster," which refers to the person in charge of overseeing an email system, is where the word "webmaster" originated. To keep the website live, an administrator works with the website provider to manage the web server. Both contributing material and creating the website's code—in both the front-end language of HTML and the back-end language of PHP or Perl—are their responsibilities. A website's main point of contact for users is the administrator, who also receives guest comments and handles any problems that arise.

The phrase is less frequently used now than it was in the early days of the Internet, when it was not only feasible but also typical for one person to manage every element of maintaining a website. A contemporary website needs more complicated technology, which calls for a diverse set of abilities. Delegating duties to multiple team members with more specialized responsibilities and job descriptions has become more commonplace.
