The key indicator of web site availability is speed. More specifically, the speed at which a page can appear in a visitor's browser window. There are many factors that affect the speed, including the speed of the web server, the Internet Connection of visitors, and the size of files that must be downloaded by the browser. Although you cannot control the server and connection speed, you can control the file size on the web page of the website.
To make websites faster, Web builders compress and op
