What methods should you use to decrease the loading time of a website?

We should follow the following instructions to decrease the loading time of a website:

Optimize images: You can optimize images and decrease the file size without affecting the quality of that image. You can use the external picture tools to resize your images such as the Photoshop, picresize.com and more. Furthermore, use fewer images (avoid them unless necessary).
Use browser caching: Caching involves temporary storages of web pages that helps reduce bandwidth and improve performance. When a visitor visits your site, the cached version is presented that saves the server’s time and loads pages faster. So, use browser caching to make the process easier and faster for your repeat visitors.
Use content delivery network: It allows you to distribute your site across several servers in different geographical areas. When visitors request to visit your site, they will get the data from the server closest to them. The closer a server, the more quickly it loads.
Avoid self-hosted videos: Video files are usually large, so if you upload them to your web pages it can increase their loading time. You can use other video services like Youtube, Vimeo, etc.
Use CSS sprites to reduce HTTP request: It allows you to combine some images within a single image file by implementing CSS positioning of background. It helps you to save your server bandwidth and thus loading time of the webpage decreases gradually.
