Web Performance Optimization (WPO) refers to the techniques and strategies used to improve the speed and efficiency of a website. A faster website enhances user experience, leading to higher engagement and satisfaction. Key aspects of WPO include minimizing file sizes, optimizing images, and reducing server response times, all of which contribute to quicker loading times. Another important element of WPO is the use of tools like Google PageSpeed Insights and GTmetrix to analyze website performance. These tools provide valuable insights and recommendations, helping developers identify areas for improvement. By implementing WPO practices, businesses can boost their online presence and retain more visitors.
