As the website’s administrator, the webmaster is in charge of virtually all aspects of how their site functions. Their primary duties include maintaining a website’s content and ensuring that the design displays properly across all platforms. They also troubleshoot problems and ensure that the server is adequately handling web traffic. Webmasters may also code new functions for the site and migrate files between their internal server and an online production server. Most webmasters handle the management duties for more than one online property at a time.
