What does a website tester do?

As a website tester, your job is to test and evaluate the performance of a site on the internet. In this role, you pretend to be a normal user, consider the design and usability of the site on your computer, and provide feedback on the site's performance. Quality assurance (QA) is a critical part of proper web development, and you may work on the same site through several iterations of its design and performance. Jobs that focus entirely on testing websites exist, but many companies also wrap this into a programming or design position. As such, you should search for other jobs if you want to develop sites alongside testing them.
