Definition

Deep Dive
Site speed is a measurement of how quickly the content on a website page loads and becomes interactive for the user. It encompasses various metrics, including the time it takes for the first byte of data to arrive, the rendering of the main content (Largest Contentful Paint - LCP), and the stability of the layout (Cumulative Layout Shift - CLS). A fast site speed is paramount for a positive user experience, reducing bounce rates, improving engagement, and ensuring visitors can quickly access the information or products they seek.
