Speed optimization involves enhancing a website's performance to ensure it loads quickly and efficiently, improving user experience and search engine rankings. This process includes various techniques, such as minimizing file sizes, optimizing images, leveraging browser caching, and reducing server response times. Additionally, using content delivery networks (CDNs), optimizing code (HTML, CSS, JavaScript), and eliminating unnecessary plugins can contribute to faster loading times. Speed optimization is essential for reducing bounce rates, increasing engagement, and ultimately boosting conversions, as users expect quick access to content and services online.
