Minification refers to the process of removing unnecessary or redundant data without affecting how the resource is processed by the browser – e.g. code comments and formatting, removing unused code, using shorter variable and function names, and so on
To Enable Minify we are using Autoptimize :
This plugin is supposed to compress and move files such as styles and scripts from the header to the footer. It will also minify the HTML, making it as lightweight as possible.
2. Optimize Images
Optimizing your images will help your WordPress site load faster.
Download and activate WP Smush.it This plugin will optimize every image you upload and you can use the Bulk Smush.it feature to smush all of your uploaded images.
Alternatives to WP Smush.it include EWWW Image Optimizer, CW Image Optimizer, Imsanity andHammy. Many WordPress users prefer using these plugins as they do not rely on an external server to process your images.
3. Server / Hosting
Sometimes slow speed can be a result of your hosting service. Some hosting services used shared hosting which can have an effect on speed. This is a very broad topic but the general idea is that some hosts are better than others. We run our own website using a Cloud plan from Siteground, a leading company provides managed WordPress hosting.
