Learning website speed optimization starts with understanding how websites load and the factors that affect performance, such as image size, code efficiency, server response time, and caching. Begin by studying basic web technologies like HTML, CSS, and JavaScript, then explore optimization techniques such as image compression, minification, lazy loading, and using Content Delivery Networks (CDNs). Practice by analyzing websites with tools like Google PageSpeed Insights and improving their performance step by step. Consistently experimenting, testing, and staying updated with new performance practices will help you master website speed optimization.
