Metadata helps the web browser define the web page. It organizes information as well as make the website look the way it does. Even though it's not visible to the typical viewer, it's important because without it, the website would be very messy. Metadata tags such as viewpoint allows the webpage to show up to size on a tablet. Otherwise it would look really small on a tablet compared to a computer. Others, like description and author reveals information about the website and its creator. Style obviously glamours up the website and makes it look pleasing to the eye.
