Minification is a key practice for Web Performance Optimization (WPO). By reducing the file sizes of your core CSS and JS assets, your web server has less data to transmit to the user's browser. This directly translates to faster page load speeds, reduced bandwidth consumption, and a better user experience, especially for users on mobile devices or slow networks. It is also an important factor that can positively influence your website's SEO (Search Engine Optimization) score.
